Do Compact Fluorescent Lamps (CFLs) Light bulbs flicker?
The first compact fluorescent light bulbs flickered when they were turned on because it took a few seconds for the ballast to produce enough electricity to excite the gas inside the bulb. Thanks to the refined technology in new compact fluorescent light bulbs, there is now no significant flicker (less than 1 second). However, these bulbs do require a short warm-up period before they reach full brightness, which is why they may appear dim when first turned on. Compact fluorescent bulbs are best used in fixtures that are left on for longer periods of time, rather than in fixtures that are turned off and on frequently. Do CFLs light bulbs contain more mercury than incandescents ? All CFLs and fluorescent tubes contain a small amount of mercury, which is key in producing the light. It’s not ideal but incandescents are probably responsible for more mercury emissions than CFLs; burning coal for electricity emits mercury, and incandescents use much, much more energy. CFLs can be safely recycl
