Do leds handle fluctuating/high voltages well?
In our area, the electric company runs the power in the main lines high, and the power levels fluctuate. The result? Incandescent light bulbs burn out very quickly, and fluorescent light bulbs do not last anywhere near their alleged lifetimes. They do last longer than the incandescents.
The wiring in the entire house has been checked, and certified in good shape by licensed electricians. They believe the problems with the light bulbs and other appliances are due to the power levels in the main power lines in the community. One suggestion is to use incandescent light bulbs rated for 130 volts. These do indeed last longer than 120 volt light bulbs, but they eat power compared to fluorescents and leds.
So how would leds fare in this situation? Or how should I ask this question of led salespersons or manufacturers to find an answer to this question?
