Why Do CFL Flicker?
Compact Fluorescent Light, also known as Compact Fluorescent Lamp is discovered as an energy saving light. It replaced incandescent lamps and compared to any general service of the old model of incandescent lamps, CFLs have longer life and use lesser power.
Most of the time, once you turn on a compact fluorescent lamp, it flickers. The real reason behind this is, it takes a while for the ballast to produce electricity to ignite the gas inside the bulb. Old products of CFLs have this particular issue. But nowadays, they have already invented and produced another kind of CFL which never flickers once turned on.
However, these bulbs may still require short period of time to warm up before it reaches the full brightness. Going back, sometimes, there are instances in which the CFL just continues to flicker and never get to stability. But if you try to turn it off and turn it on again, the bulb will be in its full power. This is because the flow of current inside the wires are not enough to make the bulb lit. You need to restart or refresh the whole system again to achieve the right brightness.
Electricity is a great factor why CFLs flicker. CFLs are designed to have a certain amount of electricity first to make it work. The electricity triggers the gases inside the bulb to ignite and excite. Compact fluorescent lamps can be best used as fixtures left for long period of time than fixtures that are frequently.
Flickering results to fluctuations of the temperature and light output. The CFLs normally do that to supply the right frequency of electricity. Each tube of electrode produces different light output on each cycle. Resulting to different rates of flickering and it may also appear dimmer as what it is supposed to be. In a matter of seconds, full cycle of brightness can be achieved.
