Why do fluorescent bulbs burn out quickly?

Answer 1

Hi are you getting the right voltage bulbs to low will blow fast a malfuntioing transformer will also aloow to high a voltage to the bulbs or if you live in an area that's prone to voltage spikes

Answer 2

ANSWER:One of the byproducts of Mercury vapor and argon gas is luminescence or light. The bulb is full of gas and when you turn on the switch, the starter will fire an electrical charge on both ends of the bulb exciting the gas inside and a small amount of mercury emits vapor and the gas molecules collide and excite more molecules nearby until the entire contents are excited. This makes the bulb get brighter until it reaches its maximum brightness. The white phosphorous coating inside the bulb increases illumination. If It didnt have this powder coating, It would be a black light. In cooler temperatures, you can see the pulses of the light as it goes from one end to the other in waves. Tha average bulb reaches full brightness in about 15-20 seconds on average.

Answer 3

They don't. Fluorescent bulbs work by exciting the gas inside the tube, which in turn causes light to be emitted. Very little power used to achieve this, and very little heat is produced as a by product, in contrast to incandescent bulbs, which produce light by heating a filament until it is hot enough to glow.

It is a known factor that light diminishes with age of the lamps. most of the trouble is the starting circuit that fail to start the hi voltage needed to vaporize the gas.

Answer 4

Be cause people use bare hands to install them rather then a clean soft cloth and the oils in the skin cause hot spots as the oils burn and cause bulb failure

Answer 5

Too much heat is usually the culprit. However, in rare cases it could be a faulty power source.
