Zoinks! Its Dr. Z, the lama of luminescence here to help you find a better way of lighting. Do you remember when you were a little kid how much fun it was to flick the lights off and on really fast? (in Mr Y’s case this has continued on to his adult life) Well I certainly remember the childhood joys of such activity (until I found a much better way of producing that effect.. strobe lights! ) But more to the point.. This age old pastime is putting the life of your compact fluorescents in jeopardy.

Compact fluorescents are best when they are on for a long time. These lamps can take up to 3 mins to warm up before the achieve full brightness. Now this probably will not be noticed by most users but the lamp does need some time to warm up for efficient operation.  Compact fluorescents are best suited to place where you need the lights on for long periods (10 mins and up). Switching them on and off frequently will greatly effect their life and will not allow you to reap the energy saving benefits that these bulbs allow for.  If you have an area where you are turning the light on and off alot you may want to stick with good old fashioned incandescents. If you are like Mr. Y and like flicking those lights on and off really fast just for the fun of it.. I suggest the strobe light it is much more useful for stimulating the alpha waves..

p.s. Strobes and strobe like effects (like flicking the switches)  can trigger seizures in photosensitive epilepsy. Thus, most strobe lights on sale to the public are factory-limited to about 10-12 flashes per second in their internal oscillators, although externally triggered strobe lights will often flash as frequently as possible. At a frequency of 10 Hz, 65% of affected people are still at risk. The British Health and Safety Executive recommend that a net flash rate for a bank of strobe lights does not exceed 5 flashes per second, at which only 5% of photosensitive epileptics are at risk. It also recommends that no strobing effect continue for more than 30 seconds due to the potential for discomfort and disorientation. (Wikipedia)
