LEDs

A factor in the cost of LEDs is the controller. LEDs shouldn't be brightened and dimmed using a simple control like a rheostat. For max efficiency, LEDs should be full on or full off. So LEDs are controlled via pulse width modulation. Wide "on" pulses make the LED brighter, narrow "on" pulses make the LED dimmer (given the integration time of the eye). For longevity, LEDs are not driven at 100% duty cycle.

TLDR, LEDs are strobe lights!

we've switched about half our bulbs from compact fluorescent to LED, they look good. I recently bought a husky brand LED work light, it's bright without getting hot and the bulb should last decades longer than the halogens in my other lights but a fall from 4 feet and the bulb quit working. H0me Desp0t did replace it for free

Its like you have to keep a file on each bulb with receipts and locations to secure the warranty.
