You can save up to $55 a year by replacing an incandescent bulb with a dimmable LED and using it regularly at low levels. Beyond energy savings, dimmers add comfort and convenience. However, dimming technology has had a hard time keeping pace with advances in CFL and LED bulbs. Problems include:
Levitons SureSlide Universal Dimmer 6674(about $25 through our affiliation withamazon.com) This dimmer has an on/off preset function that remembers your preferred setting and is compatible with Decora wiring devices and wall-plates. It does require a neutral. Learn more at leviton.com.
Lights dropping out. CFL and LED bulbs will sometimes turn off before the slider reaches the bottom.
Timers for bath fans are important because excess humidity can cause everything from window condensation and mildew to moisture and rot inside walls. Timers connected to exhaust fans must be rated to run electric motors, which makes them more expensive than those running incandescent lamps. Some new wall switch timers have dual controls for turning off both lights and fans after a preset time. For the ultimate in smart bath fan timers, buy a humidity-sensing fan designed to automatically turn on and off as moisture levels at the ceiling rise and fall.
There are many types of illuminated switches made by many manufacturers. We show two types of toggle switches and a rocker switch here.
Occupancy vs. vacancy sensorWhats the difference?
It sounds like a joke: How do you find a light switch in the dark? Illuminate it, of course. These great little inventions use a tiny bit of electricity from the circuit theyre on to light a small LED or neon bulb. They install as easily as regular switches, but be aware that these switches work fine with some CFLs but not so great with others.
Levitons Universal Dimming Sensor(IPSD6-1LZ)is an occupancy sensor and dimmer in one unit. It has a 180-degree field of view for up to 900 sq. ft. of coverage and includes manual presets for delayed-off time settings (about $40 through our affiliation withamazon.com). Compatible with dimmable LED, CFL and incandescent bulbs. It does not require a neutral. Visitleviton.com.
Turn off the power and use a noncontact voltage detector to check that the circuit is off before you remove the cover plate.
Lutrons Maestro occupancy/vacancy sensor switchfunctions in both modes depending how its programmed. Its available in two modelsone for small rooms (MS-OPS2; about $20) and one for larger rooms (MS-OPS5; about $40).

Lights turn off unexpectedly. Dimmable CFL and LED bulbs can be affected by line voltage fluctuations and they can turn off (not just dim or flicker, like incandescents) when a hair dryer or vacuum cleaner is used.
Those with randomized settings can vary on and off times, which adds a heightened level of security by fooling burglars into thinking someone is home when youre away. The newest (and most expensive) astronomic timer switches are compatible with CFL and LED bulbs in addition to incandescent and halogen bulbs. Non-compatible timers can cause CFLs to flicker and shorten their life span.

The dimmer packaging will usually tell you if the dimmer requires a neutral wire.
Automated outdoor lighting is convenient, but the smartest timers are astronomic versions that turn lights off and on from a memory of 365 days of sunrise and sunset times based on your homes location. This feature is particularly useful if you live in a northern climate which has a wide range of daylight hours from summer to winter. Simply find the longitude and latitude of your home at enter it into the timer. The timer automatically calculates the sundown turn on time. Then choose either a set run-time or let the timer turn the lights off at sunup. Such timers include:

Buysmart light switchesfor convenience, safety and to save money. Some light up for easy switching at night, some switch on and off automatically, some are timed and others dim. In most situations you can easily install smart light switches yourself.
Reduced dimming range. Unlike incandescent bulbs, most CFL and LED bulbs will not dim to very low levels. Some dimmable LED bulbs can get close, but it depends on a specific bulbs circuitry.
Levitons Vizia VPT24-1PZ indoor/outdoor programmable timer(about $40 through our affiliation withamazon.com). This timer comes with three different color faceplates and a five-year warranty. It requires a neutral wire. Learn more atleviton.com.
Lights not turning on. After you dim a CFL or LED bulb, it sometimes wont turn on until you move the dimmer slider up. This pop-on effect can really be frustrating in a three-way situation where a light can be controlled from several switches, not just using the dimmer.
Residential occupancy and vacancy sensors have come of age. Most residential sensors use passive infrared (PIR) technology to detect heat and motion and turn lights on and off accordingly. They can cut lighting costs by 50 percent in rooms where lights are frequently left on when no one is in them. Wall-mount sensors install just like a light switch and are available as switches or dimmers. Most require a neutral wire, but there are a few models that dont. The smartest sensors are designed to screen out background interference and detect small movements and natural light. They also work with LED, CFL, incandescent, halogen and other bulb and load types.
If your switch is wired like this oneconnected to a wire wrapped with black tape and a black wireboth wires are hot and neither can serve as a neutral.
For a broad selection of illuminated toggle and rocker switches, . Youll find clear, white and red toggles and black, white, ivory and other colors of rocker switches. Prices range from $7 to $40 through our affiliation m. The Web site also carries a huge and reasonably priced selection of low-voltage lighting, switchplates and other items.
Many of the new, sophisticated smart switches require a neutral wire to run the circuitry inside the switchparticularly those compatible with LED and CFL bulbs. Before you buy a new switch, check the packaging. Most will specifically tell you if a neutral is required (Photo).
Anoccupancy sensorautomatically turns lights ON and OFF. Great for areas where lights are accidentally left on a lot, like in a kids room, or where your hands are full, like in a laundry area.

The good news is that dimmer switch technology is improving. The newest switches work well and can effectively dim mixed light sources on the same circuit. The bad news is these switches are pricey and they require pricey dimmable LED and CFL bulbs (they also work fine with incandescent and halogen bulbs). A list of compatible bulbs can be found on manufacturer Web sites. Some require a neutral and some do not, so check the packaging carefully.
