Fluorescent light fixtures sold in hardware stores as of 2010 are a little different than the ones sold a decade ago. Today's fluorescent fixtures feature electronic starting ballasts, while older versions used an independent starter to kick-start the light. In these older fixtures, a non-working...

Ultraviolet rays produced by the excited atoms strike a phosphor coating on the interior surface of the bulb, causing it to emit visible light. Fluorescent lamps are much more efficient than incandescent lamps because the excited atoms give off little of their energy as heat. Compare incandescent ...
Note: Passing the continuity test doesn't guarantee a bulb is good. A bulb can show continuity but still have other problems that prevent it from working. Step 4 If you have an older fixture, the problem may lie with your starter. This is the small box that is placed on or near the...
intact. Electrically speaking, if there is continuity across the pins, the electrode should be working. However,even if the electrodes are intact the bulb may not light.This can occur if some or all of the gas has leaked from the bulb... a condition for which there is no sniff test!
A starter switch for a fluorescent lamp including a microswitch actuated by an electrically heated bi-metallic expansion element. A second bi-metallic element is provided to compensate for changes in ambient temperature, thus rendering the initial switch adjustments independent of surrounding temperature ...
4. Adopt the Taiwan Epistar LED Lamp which have high lumen and low light loss, light loss is less than 5% during 3000 hours. Application: Office, Supermarket, School, Hospital, Lobby, Hall, Square, Parking and so on. Install Instruction: Take down the "Starter and Electr...
The colour andspectral compositionofradiated lightwill depend upon the phosphors used. Lamps can be made with a ‘white’ appearance but with widely different efficacies or colour rendering properties.

The impending ban on incandescent light bulbs has found many vocal opponents, including those who says CFL or LED bulbs just can’t match the warm glow of an old-fashioned incandescent. We tested all three to find out if they’re right.
