With some LED floodlights, the current is enough to give a faint glow. The Phosphorous used in the led is experiencing chemiluminescence, a cold chemical reaction that produces light. The Phosphor is normally used to be give leds their white color through photo luminescent reaction, reacting to photons of a different wavelength, but it can glow in the dark without that. My Led's are powered off the AC wall switch then thru a a .39 capacitor then bridge rectifier they will burn forever even when switched off and when it is completely dark you get enough light to see. The leakage of current can be due to the design of the solid state switch or due to the aging of the switch. Learn about 7 main symptoms you may have when you dim LED lights. It just bleeds off enough from the LED readout to allow the fixture to turn completely off. when lights are switched off there is still a faint glow from leds.
