re: Remember when they told us LED bulbs would last 20 years?

Another dirty little secret is they lose their brilliance very fast...no matter how good a driver they have all LEDs degrade very fast...so that 100 watt lamp equivalent that is supposed to last 5 years and use the same amount of energy as a 30 watt lamp will only be 100 watt equivalent for a few hours...they start to degrade immediately. Depending on the quality of the LEDs and the driver they may lose up to half the light in 6-8 months...most sold in big box stores are designed to do so. All lamps do this, none at the speed that LEDs do it. It is noticeable from the time you turn them on...they will all be noticeably dimmer when they have been on a while. Once turned off and back on they will be slightly dimmer than they were when they were turned on last time.
