Compact fluorescent light bulbs contain mercury, which is a dangerous and hazardous material. But that’s not the only reason not to like them. Gomestic.com lists some of the other disadvantages of compact fluorescent light bulbs:
- CFLs evolve and newer models are getting better and better all the time. Still, they are not as versatile as incandescent lamps, and can’t be used for every household requirement. For example, CFLs usually take some time between being switched on and achieving full brightness. This time is even longer as the CFL approaches the end of its life. Cold temperatures make the situation even worse, with some CFLs not even starting in cold weather.
- Another downside for CFLs is that their lifespan is shortened considerably when they are switched on and off within short time frames. Think of the light that comes on automatically as you approach your garage, and then turns back off after a few minutes. CFLs are not a good option for this or other light activated motion sensors.
- CFLs are also not very suitable for dimming. If you require a dimmer controlled light source, CFLs are not a good option. Dimming shortens a CFL’s lifespan considerably, and the dimming range is disappointing. You’d really be better off sticking with a regular, incandescent light bulb for dimmed rooms.
- CFLs, unlike incandescent lamps, emit ultra violet and infra red light. The ultra violet light may damage paintings. The infra red, on the other hand, may interfere with remote-controlled devices such as your TV – since these will interpret the infra red light as a signal.
It’s outrageous that Uncle Sam is banning incandescent light bulbs and forcing Americans to use dangerous and inferior compact fluorescent light bulbs. So if you have a compact fluorescent light bulb that doesn’t work any more, send it to Washington. Let them know what you think about their meddling.
