Yes. By using the proper equipment neon/cold cathode lamps can be successfully dimmed. Lutron Nova? low voltage dimmers and GRAFIK Eye? controls are UL listed for neon/cold cathode loads. All Nova? low voltage dimmers require a neutral wire. For more details, contact the Lutron Hotline and request Application Note #25. Yes, dimming increases incandescent lamp life. Halogen lamps are incandescent lamps with a tungsten filament.

Yes. However, the lower the temperature, the lower the light output and the higher the required starting voltage. We recommend using lamp heaters in cold ambient conditions. See similar questions...

Yes, only if the fluorescent light is using a dimmable ballast. Any time a dimmable ballast is used, a compatible dimming switch needs to be installed. The ballast manufacturer can provide a list of compatible switches. See similar questions...

Please refer to our state disposal policies page. In most states, fluorescent and compact fluorescent light bulbs used at home can be disposed of in the same way as regular light bulbs. While all fluorescent bulbs contain a trace amount of mercury, the quantity is so minute that household disposal is not regulated by federal standards (established by the U.S. Environmental Protection Agency).

In the uppermost vertical section of your plenum both hot and cold cathode tubes suffer diminished effectivness based on cooler temperatures. We overcompensate with excessive UV-C wattage to get a maximum kill without ozone. Hot cathode is more effective than cold cathode when installed at the condenser coil. See similar questions...

Ballasts are used to regulate the current in the lamp. Current needs to be regulated in order to supply the right amount of power needed to make the arc, and thus the light, in a fluorescent lamp. Fortunately, the current is lower than that needed for a typical incandescent. This is the reason why the fluorescent lamps can provide the same light output for less energy than typical incandescents. See similar questions...

There is no danger in doing this, but you will get light only in the middle one of the three "on" positions. See similar questions...

Lamp manufacturers generally strive to minimize ultraviolet light (UV) radiation in all lamps used in general lighting applications. The amount of UV produced by standard fluorescent lamps, such as those in your office, home, or school, is not hazardous and does not pose a major health concern. In fact, a paper by the National Electrical Manufacturers Association (NEMA) explores this subject in more detail. See similar questions...

Always check the light package for exact recommendations, but generally, compact fluorescent lights can be used in the 20°F-140°F range. Many new products like ParaLite lamps will start at temperatures to -20°F, though the light output may be somewhat reduced at very low temperatures. When compact fluorescent lights operate at temperatures above 140°F, there may be reduced light output and premature ballast failure. See similar questions...

Regular incandescent lamps produce light by passing an electric current through a filament in a vacuum or gas filled bulb. They provide low initial cost, good color rendition and excellent optical control. Halogen lamps also use a filament; but since it is sealed in a pressurized capsule containing halogen gas , the lamp provides brighter, whiter light and improved energy efficiency.

When a 2.6mm diameter CCFL is operated at the specified drive current of 6mArms, the ends near the electrodes will be approximately 50° C above the ambient temperature. The body will be approximately 25° to 30° C above ambient. See similar questions...

Color temperature depends upon the phosphor used to manufacture the lamps. The most common industry lamp phosphors produce the following color temperatures. See similar questions...

The lamps are rated for 30,000 hours, but dimming the lamps shortens life. Color temperature remains relatively consistent for 10,000 hours. Astron recommends you change all lamps once every two years, at a total cost to user of about $450.00. See similar questions...

A - Yes, fluorescent lamps do flicker, but the newer technologies that utilize electronic ballasts operate at levels where the flicker is beyond human perception. The older magnetic ballasts operate on 60 cycles per second (60 Hz), and the lamps actually flicker on and off 120 times per second. Many people feel they can see them flicker, especially in presence of computer or TV displays. See similar questions...

Unfortunately color meters available to cinematographers are far from being scientifically accurate when reading fluorescents. They act as a great comparative tool to determine differences between two given light sources but are inadequate in providing definitive data. You will rarely find two color meters, even if they are the same make and model, that provide equal data. Results between meters may be similar but not identical. See similar questions...

Compact fluorescent lamps, also known as CFLs, are a type of fluorescent lighting; fluorescent lighting has been around since the 1940s. Tube-shaped “linear fluorescent” lamps have long been popular in business and commercial settings, as well as for household uses such as in garages, kitchens, and recreation rooms. Smaller, compact versions of fluorescent lamps, CFLs, first appeared in the 1980s. See similar questions...

The difference between cold cathodes and LEDs is this: LEDs are bright, and CC's are incredibly bright!! Mastermods.com used to sell light kits but have had incredible shipping problems and they are generally not reccomended. There are also some tutorials to make your own. Here is the best one (thanks Ben999_): Circular cold cathodes are becoming extremly popular...they are available at Xoxide.com or any major computer case modding site. See similar questions...
