CREE LED Light Bars

Posted on: May 9, 2018, by :

These light bars come well-packed in sturdy boxes, and feel solid despite being significantly lighter than most other brands at the same size. The mounting brackets seem a little flimsy for the bigger sizes, but the latest Rigidhorse light bars also get high marks for durability. Some drivers have reported logging thousands of cross-country miles through rain, ice, and drifting sand without any light bar issues whatsoever.

A total of 40, 3-watt high-intensity CREE LED lights

The 7D weighs 10.4 pounds with dimensions of 44.1 x 6.1 x 5.8, while the 5D weighs 12.1 pounds and was an inch or two smaller on every dimension. Both promise a 50,000 hour lifespan, anticorrosive material, and a shockproof, waterproof, dustproof design. Both series feature an aluminum housing, aluminum brackets, and a polycarbonate lens.

Another category of off-road vehicles that can benefit from extra lighting are construction vehicles like backhoes or excavators. These circumstances almost guarantee uneven surfaces with lots of shadows.

The Autofeel 8D Light Bar is the latest in a long line of Autofeel light bars intended to be affordable, easily mounted on most vehicles, and provide superior illumination even in adverse circumstances. The current generation of 8D Light Bars are built around a quad-row system of LEDs, i.e. four independent rows set one after the other. Combined with a curved reflection system, this enables an intense amount of light (up to 86400 lumens) to be beamed from the roof of the vehicle. This is much brighter than any headlight, even the more powerful high-beam units, and is sufficient illumination for any campsite or worksite that needs to be set up after dark. It is also more than enough light to drive away nuisance animals and even be seen by distant motorists or aircraft, increasing its search-and-rescue assistance potential.

The Autofeel 7D 32 Inch Curved LED Light Bar features ultra bright, tri-row, CREE LED bulbs, polycarbonate lenses, shock and impact resistance, IP67 waterproofing, and professional grade stainless steel hardware. Its perfect for any automotive or marine application and installation is a breeze. The polycarbonate lenses pinpoint light while the reflector creates a wide beam. You get the best of both worlds with excellent overall illumination and impressive accuracy. The Autofeel can really take a beating. Its both shock and impact resistant, making it ideal for extreme motorsports. This light bar is so strong that driving a truck over it will barely leave a scratch. These next generation 7D CREE bulbs are up to 50% brighter than the competition and offer a full 1-year manufacturers warranty. The LEDs provide a bright, white light thats more natural looking that traditional bulbs. This LED light bar will truly light up your night. The mounting brackets, nuts, bolts, and washers are all made from 100% stainless steel. You wont have to worry about your mounting brackets rusting off or nuts that rust into place. With everything being made out of stainless steel or high-grade plastic, you wont actually have to worry about rust at all.

However, incandescent bulbs are far less efficient than LEDs, so a lot of that energy is wasted as heat. The more efficient the light source, the more lumens you get per watt. An LED provides brighter light while using less energy, but even among LED products, this efficiency can vary.

The flood beam produces a wider cone of light at 60 to 90 degrees. This provides some visibility to either side, important for safety when your driving down a trail, or providing the ability to illuminate a wider area such as a camp or worksite.

For the 42 LED light bar, the 7D puts out up to 64,800 lumens of brightness, while the 5D produced 40,000LM. At 648 watts and 400 watts respectively, they are both still putting out the same near-100 percent efficiency. The 7D uses 3-watt LEDs where the 5D uses fewer 5-watt chips. Both series are engineered to provide the same 30/60 spot flood combo angles.

One of your best option for increasing driving visibility is adding a Cree LED light bar. Whether its a car, truck, boat, or off-road vehicle, these devices create a wide field of bright illumination that provide extra safety when youre out in the dark. This website explains how truck light bars operate, examines how they stack up against other lighting methods, describes various ways they can be used, and shows you how to distinguish the good ones from the poorly manufactured ones. It also presents LED light bar reviews. With the knowledge offered here, youll be able to effectively pair the best LED light bar with your needs.

You may want to get thread repair kit for the aluminum mounting bolts, however, as they can strip out when over-tightened, which often happens with the larger light bar sizes, or when trying to install to odd-shaped contours on some vehicles. Thats a small investment considering that the Kansmart tri-row lights deliver more light and can endure rougher conditions than even some much more expensive light bars.

When you first light up a 7D lens, the illumination is crisp and clean across the light spread without visible spotting, and only minimal yellowing at the very edges of the flood lights. All the Cree chips seem to have a consistent color and brightness. Down-road illumination is far better than any stock headlights and at a wider field of vision.

LED light bars dont have to be limited to vehicles. They can also serve as stand-alone warning beacons at construction sites, factories, and similar locations. These are the situations where light bars equipped with strobe capacity make the most sense.

The Rigidhorse 42 inch curved LED light bar offers uncompromising quality with unparalleled performance. This LED light bar is easy to install and is virtually indestructible. It includes everything you need to get started right out of the box. The housing is made from durable, high-quality aluminum. The stainless steel brackets will resist rust and corrosion.

This light bar is dustproof, quakeproof, waterproof, and even explosion resistant. Its truly built to last a lifetime no matter what you throw at it. The lens and reflector combination offers the best of both worlds. You get a wide beam of light to cover a large area, as well as focused beams of light like you may expect from a traditional spotlight. The curved design enables you to see the sides of the road much easier at night. This light bar will easily outshine your headlights and provide you with an unparalleled view for driving.

LEDs are always more efficient than conventional lighting. LED stands for light emitting diode, which is a special compound that emits light when an electric current passes through it. Because there is little heat involved and the LED itself is a solid, stable material, LEDs are more efficient and last much longer.

When youre ready to install a light bar on your car or truck, you want to get the most impact from your new product. Numerous manufacturers offer light bars, but that doesnt mean that these products are all the same. When it comes to performance, the type of LEDs used the the light bar make a huge difference. Cree LEDs are some of the most popular for a good reason! The latest Cree LEDS in the 5D series have more power and output than ever. These LEDs are built to withstand the test of time, and they offer up to 50,000 hours of incredible illumination.

Reputable companies normally offer a wide assortment of light bars that are built with durable housing and include corrosion-proof mounting parts. An extra-large heat dissipation feature usually made of aluminum is a necessity. At the very least, both the housing and the wiring of the unit should have an IP rank of 65. An IP68 mark is preferred, and IP69K is ideal but rare. The light bar must have quality drivers that hold light output steady at any voltage within the operating ranges of either 9-30 DC volts or 10-70 DC volts. The better light bars use Cree LEDs that include specially-designed reflectors and lenses for the highest efficiency levels of 150 lumens per watt. Theyre also estimated to operate up to 100,000 hours. Finally, if the device isnt backed by a solid warranty, its best to look elsewhere.

This is the standard rating for defining the resistance of a light bar product to solid and liquid particles. IP stands for International Protection Code. The first number refers to the particle size thats blocked, and six is considered dust-free. A water-resistant level of seven is the second highest available, which means the product has been tested to be leak-free when submerged at a depth of one meter for at least 30 minutes. Thats more than enough for the wet conditions you find off-roading or even driving in rainstorms.

Cree is a leading LED manufacturer thats been providing innovative products since 1987. Crees engineers are constantly looking for new ways to get more efficiency from the LED chips that provide the light source for their bulbs. Apart from great design, one of Crees advantages is in the materials they use. Cree lights are manufactured using high quality InGaN (indium gallium nitride) materials, along with special substrates uniquely made for their products.

The LED lights in these arrays can be arranged in everything from a square pattern of four lights to a circular formation to the recognizable elongated bar thats either straight or curved. These arrays can span just a few inches to over 4 feet in width with one or two rows of lights. LED light bars can operate as either spotlights or floodlights. Spotlights project beams between 10 and 30 degrees while floodlights span from 40 to 120 degrees. The positioning of reflectors, lenses, and the shape of the bar determine which of these two patterns is produced. Its possible to have both types created by a single unit by either having separate divisions of a single row perform one or the other of these two functions or by using two unique rows.

The Rigidhorse light bars are well-made even in comparison to some expensive brands, and the oblong spot pattern at the center is noticeably brighter. The wiring harness for the larger light sizes comes with a 40 A relay, but they rarely seem to draw that much amperage. You may not even need the longish wiring harness; in some larger vehicles you can wire it easily into the dash with an inexpensive switch. The wiring harness comes with a push-button switch which may not be as easy to find in the dark, but it does make connecting the light bar easier. However, one known problem is that you have to make certain that the gaskets holding the connection pins in place remain tight.

The Tri-row series looks and feels solid enough, with a black-painted aluminum housing, and sliding aluminum mounting brackets that make mounting to different makes of vehicle much simpler. Each light bar comes with a 3-meter wiring harness and three brackets, but nothing else. Its easy to install but cant accept side mounts. The Kansmart products have the usual polycarbonate lenses and IP67 moisture-resistant rating. They will run off any 12 V to 30 V power source for a 30,000 hour lifetime of use.

IP68 means resistance at depths over one meter for a longer period.

What tells me the power of the light: watts or lumens?

To give you some idea, a traditional incandescent bulb of 60 watts provides about 800 lumens of light, for an efficiency rating of only 13 percent. Most common LEDs have an 80 percent efficiency, for instance 2900 lumens of light at 36 watts. However, a Cree light bar may provide 7,200 lumens of light at 72 watts, for a perfect efficiency of 100 percent.

8 degree spot and 90 degree flood combo pattern

There are times when an LED light bar can come in handy on the road. Youll need to determine what your states laws say about this, though. While a small light bar might be permitted, there are legal limits on how much brightness a vehicle on the road can produce due to safety concerns involving blinding oncoming drivers.

LED light bars are meant to supply ample illumination beyond what standard headlights can achieve in circumstances where visibility is impaired due to darkness, bad weather, or obscured terrain. Of course, as the following examples show, theyre adaptable to a variety of uses.

Take your off-road vehicle to the next level and enjoy an illuminated driving experience at any time with the Rough Country 20-inch X5 Series LED Light Bar.

Rough Country products are designed for toughness and durability, and this product is no exception. The light bar withstands everything from heavy force to water immersion easily, so customers can enjoy years of illumination from their investment.

Cree LEDs are so efficient that they outshine most other LED lighting products while drawing less power. Cree is the first choice in vehicle-mounted light bars for motorists, boaters, and off-roaders who need a good field of bright light, without excessive drain on the battery. While Cree distributes their lights to many manufacturers, here aretop light barsin different sizes.

This product has an average installation time of 2-3 hours, and it is designed only for off-road usage. Other exciting features include:

Rigidhorses new 5D series light bars are claiming 85 percent efficiency compared to the 60 percent of previous products. The 5D 42 light bar, for instance, produces 40,000 lumens at 400 watts of input, and the other new models have comparable high-efficiency. However, thats not a significant improvement over the 4D series. The main difference seems to be that the new Rigidhorse light bars will be using 5-watt Cree chips instead of 3-watt Philips LEDs and producing more light with fewer LEDs. For only a slight jump in price, Rigidhorse is now including a wiring harness as part of the package.

Coupled with a portable power source, LED light bars, flood lights in particular, are a boon for both indoor and outdoor needs. They can supply more than enough lighting for backyard events, and smaller ones can accommodate interior spots where the wiring doesnt reach. With an independent electricity source, theyre also useful when the public grid has been knocked out.

HPS lighting is recognized as the bluish street lights that have existed for decades. Theyre highly efficient and last up to 10,000 hours, but their color is a bit on the harsh side. They also require a ballast to activate them. Low-pressure sodium lights are an alternative that generates 50-100% more light per watt and can last up to 18,000 hours, but its light is confined to an amber hue that distorts the colors of illuminated objects.

In a combo beam, spot and flood LEDs are arranged within the light bar to provide both types of light. This gives the advantages of each bright light to see clearly whats up ahead and flood lights for a wider field of vision.

At the heart of these devices are LED bulbs. Like other diodes, LEDs allow current to flow in just one direction. but they generate light in the process. For a better understanding, an advance degree in solid state physics is helpful. Keep in mind that LED bulbs are limited in their size. Beyond a certain mass, the heat retention quickly eats into the lights efficiency. LED light bars consist of individual bulbs arranged in one or more strips of varying length. They are designed to remain lit even if one or more bulbs cease working.

The Autofeel 8D Light Bar is encased in a thick aluminum casing designed to withstand the rough treatment it is likely to encounter during offroad or extreme weather conditions. The aluminum has both the benefit of being light and of being rustproof since aluminum does not oxidize. The mounting brackets are made of stainless steel to ensure that they also are not subject to rust. Large heat sinks on the back of the unit keep it from overheating even in hot tropical conditions, while military-grade rubber barriers between components ensure that it is waterproof even when submerged. While not able to withstand the impact damage of a rollover, the thick metal casing is designed to stand up to the sort of nicks and dings that come with branches, items sliding around while being strapped to the roof, and other common impacts that would destroy lesser models.

Plenty of companies offer smaller bars, but you dont have to settle for less! Although this light bar is powerful, it is also designed for usability. The products noise-reducing design minimizes annoying vibration sounds. All Rough Country light bars in the X5 LED series also feature IP67 waterproof housing made of top quality aluminum for protection against the elements.

Autofeels triple-row 7D is the newest generation over the former 5D. While the 5D projector lens was bright and reliable Autofeel claimed it was two times brighter than the old 4D designs a quick comparison reveals some 7D benefits.

Watts is the measure of the electrical energy flowing through a device; specifically the strength of the current input from the power source. Lumens is a measurement of the intensity of the light thats produced. In general, the more watts that go into a light, the more lumens you get coming out. With traditional incandescent lights, a 100-watt bulb is much brighter than a 60-watt bulb because its designed to use more energy.

Red LED light bars can greatly boost visibility of vehicles from behind when used to augment standard tail lights. Standard lights often burn out without notice. Theyre also not easily seen in daylight. Since they last much longer, LEDs should prove to be more reliable while also being easier to spot.

There are several ways to create light for vehicles and other settings. Heres a list of the most popular methods.

Think of a spot beam as a spot light. It creates a focused light straight ahead with a cone-shaped beam angled at about 10 to 20 degrees, depending on the design of the light bar.

With the new tri-row design, Kansmart has made a radical departure from the traditional 30/60 degree spot/flood angles on the older version to a 10/20-180 degree spot/flood pattern. That provides for a much brighter spot illumination and adjustable flood lighting that vary in intensity from the 20-degree range to a dimmer, but much broader field of view at 180 degrees. This also helps reduce eye fatigue. Thats an option that could provide some panoramic views when you need them.

The die-cast aluminum construction feels solid, and the hex mounting screws stay tight even after some rough off-roading. It even comes with two different sets of brackets for mounting easily to a wider range of vehicles. Although installation isnt difficult, it would still be comforting if it came with a decent user manual to provide some guidance.

What does a statement like Lifetime of 50,000 hours mean?

This is an improved version of the incandescent bulb thats much smaller. Its filled with iodine or bromine, collectively called halogens, that, at very high temperatures, redeposit vaporized tungsten on the filament so it lasts longer.

Cree LEDs deliver superior light and performance to comparable LEDs from other manufacturers. Cree is also known for its commitment to eco-friendly practices.

The Rigidhorse brand sells exclusively on Amazon, but their light bars more than live up to the competition. Slickly designed heat-sink fins and a one-way pressure release valve contribute to the upper-end 50,000 hour lifetime. These lights have a visually appealing, metallic-finish aluminum housing, die-cast mounting brackets, and unbreakable polycarbonate lenses. Rigidhorse light bars also have the IP67 waterproof rating, and a 30/60 degree spot/flood combo. The new 5D reflector lenses provide visible improvement in the light distribution over the wider angles, while the spot provides very bright illumination for more than 100 yards ahead.

Rough Country x5 The Best 20 Inch CREE LED Light Bar

A high initial cost is the only real drawback of LEDs, but over time, they pay for themselves through their very long lifespans and energy savings. They dont need a ballast, and theres no excess heat. They also dont require a warm-up period. By adding chemicals to their composition, they can produce light anywhere along the spectrum.

Autofeel 7D The Best 32 Inch CREE LED Light Bar

LED light bars with high water resistance ratings make excellent additions for any size boat. Fog is a common problem off-shore that these fixtures can deal with effectively. Small light bars can supply interior illumination in the various sections of larger craft.

Moisture Breather technology to reduce annoying moisture build-up behind each lens

What is the difference between spot, flood and combo beam?

No matter which 7D model you opt for, youll find the Autofeel products provide excellent performance and value.

There are multiple Autofeel 8D Light Bars designed to meet the needs of almost any user. From those who only want superior illumination to those who need to take near-sunlight levels of illumination into the wilderness, there is an 8D light bar will fit almost any vehicle. The mounting brackets require no drilling to install and can, with additional windshield brackets, be mounted on the windshield line instead of the roof. Connection into the vehicles electrical system is easily done with basic tools and the Autofeel 8D, thanks to its LED setup, draws minimal power from the cars electrical system. Therefore the Autofeel 8D Light Bar offers a superior lighting solution for any vehicle that needs more than just headlights.

Off-roading is what LED light bars are most closely associated with. They have huge advantages in this venue. Because they come in assorted sizes, theres a light bar to fit anything from a small ATV to a massive 4WD pickup. Since the lights are solid pieces, they wont get shaken apart on rough trails. Theres also little power consumption, so theyre perfect for ATVs that cant afford the weight of more batteries. If overnight camping awaits at the end of an off-road adventure, they provide superb illumination when getting things established, and their low electricity usage means you can shut off the engine.

The LEDs also have an incredible range of color options that run from infrared to the visible spectrum from red to violet to ultraviolet on the high end. Within the visible light range, higher frequencies that move towards the violet end provide better illumination, but the trade-off is they cause greater eye strain. The ideal color matches typical daylight with a color temperature of 5,500K. a light bar relies on a driver to keep current constant inside the voltage range its rated for. Some light bars offer pulse width modulation or PWM drivers that conserve power by pulsing the light at hundreds of cycles per second. At this speed, the light appears continuous. LED light bars also have dust and water resistance capacity designated by an international protection or IP code. The first number goes from 0 to 6 and specifies dust resistance. The second one goes from 0 to 8 and specifies water resistance with a 9K rating for high-temperature, high-pressure water exposure.

Cree LEDS provide a great value for your purchasing dollars since they can last up to 23 years! In addition, these lights use significantly less energy than traditional incandescents or CFLs. These lights do not use any mercury or other toxic materials, so they are also better for the environment. When you choose a Cree LED light bar, youll enjoy exceptional performance, impressive output and reduced energy consumption.

The longer you keep an LED illuminated at one use, the hotter it gets and the more its useful life is diminished. Light bars have to be very well-designed to even get an L70 rating of 50,000 hours. TM-21 is the new IES standard by which claimed L70 ratings become calculated ratings with sufficient LM-80 testing.

In short, the triple-row 7D design provides much more light and relatively lower power demands, but still has all the best features of the 5D series. And it only costs a little more.

That is the estimate of the useful lifespan of an LED light bar. L70 is the industry standard established by the Illuminating Engineering Society (IES). It expresses how many hours you can get from a light before it drops to 70 percent of its original output. The L-rating in new products comes from LM-80 testing, which measures light output at three different temperatures to test lights under different environments.

Autofeel 7D The Best 52 Inch CREE LED Light Bar

Light bars come in three beam patterns: spot, flood, or combo.

Rigidhorse The Best 42 Inch CREE LED Light Bar

The new Kansmart is brighter than the old version, but thats relative to size. You dont want a small light bar on a big truck. But where the Kansmart seems to really shine is in the quality of the build. The seals, gaskets, and mounting brackets are tight enough so you wont see vibration or any condensation inside the lens in even the wettest conditions.

While you might not be able to employ an LED light bar on a moving vehicle, theres rarely restrictions against having one available to make the vehicle noticeable when its stationary. A detachable one is also helpful for putting plenty of light on the auto for emergency repairs like tire changes.

What to look for when buying a LED light bar

Are Cree LEDs really more efficient?

This is most familiar as the old-fashioned incandescent light bulb. Their well-deserved reputation includes lots of excess heat, low efficiency, and short lifespans of around 2,000 hours. These bulbs are noted for developing a haze inside the glass as the tungsten filament is vaporized.

Rough Countrys 20-inch X5 Series LED Light Bar provides some of the most powerful illumination currently on the market. The bars 10,800 Lumen 120 Watt output is bright enough to light even the darkest evenings. Much of the impressive brightness comes from the products unique X-pattern design. This gives customers an extra half-row of Cree LEDs compared to similar dual-row bars from other manufacturers. In fact, the 20-inch X5 Series LED light bar offers more LED lights per square inch than any other light bar. This makes off-roading more safe and enjoyable at any time of night.

HID lights are also known as xenon lights. These are the headlights used in luxury sports cars. To confuse things, the xenon gas is used to get the reaction started, but metal halides produce most of the light once they kick in after a few minutes. Theyre not quite as efficient as HPS lights, but their light roughly matches the spectrum of sunlight. Like HPS lights, they require a ballast.

Autofeel 7D series uses the brand new triple row Cree lenses and delivers unparalleled light performance. The light bars have excellent build quality, smooth edges, and respectable heft, in an all-aluminum case. The LED chips give out 6000K bright white light without the bluish color of LED headlights. The light is thrown higher, wider, and farther down the road than the headlight high beams, and without any hot spots. The 7D technology lenses and reflectors deliver 93% lighting efficiency where old products deliver only 30-60% efficiency. The polycarbonate cover material is well sealed so that condensation does not occur inside the unit. Furthermore, the improved aluminum alloy heat sink increases heat dissipation so that the lifespan is lengthened to over 50,000 hours of operation. The light bars come with heavy duty wiring and a direct plug and play relay and light control switch. Although there are no instructions included, installation is simple with the included harness; simply connect power to vehicle power, ground to vehicle ground and attach the switch. An anti-theft wrench assures that the light bar cannot be easily dismounted.
