There you will find an extensive cross-reference guide. Note the cost per kilowatt hour is available from your utility. Never disassemble or modify the lamp. Use only on 120V 60Hz circuits. Install and remove lamp from fixture by grasping plastic base.
Photo cells contain a silicon chip that converts radiant energy into electrical current.
Most photo-cells today do this in a manner that is incompatible with the electronic circuitry in electronic compact fluorescent bulbs, resulting in a shortened lamp life. Timers are devices that allow a trickle voltage to cycle through the built-in transformer when the lamp is off. This causes the lamp to try and start itself when there is not the proper supply voltage present. Short lamp life is the result. In both cases our compact fluorescent bulbs are labeled as unsuitable for such use because the user would not realize the average rated life from this bulb when used in this manner.
