Great answer about CFLs. May I ask one more question? It is commonly said that flicking a fluorescent bulb on and off lessens the bulb's life span. Mostly I read that a fluorescent should be left on for no less than 15 minutes. That makes them inappropriate for many places, like closets or stairways, where light is needed for a short time. (Well, that and their extended warmup time.) Is this true?


I was just wondering the same thing. I hate to throw out perfectly good bulbs, but I guess it will benefit me in the long run. I have noticed how much longer the CFLs last. I guess I will finish changing them out today! Thanks for the answer.

Error Nuker

Thank you for good advices and article.


Ha, lucky me, because I quit using lightbulbs! they are really annoying and besides, you have to change them over and over... I'd rather use LED lights!

Solar Panels

Better yet, replace your bulbs whether incandescent or fluorescent with solar panels.This is the most sustainable way to use free and renewable energy plus it does not use any gasoline or coal so it basically is harmless to the environment.


Interesting, but what I have wondered about this is should you keep either a fluorescent or regular light on as this uses less energy or turn them off only to turn them on again which uses more enegy?? Does this deoend on the type of lightbulb which is being used.
