Do LED grow lights degrade over time?
For LED grow lights, rated lamp life indicates the point at which the light emits 70% of its original lumen output. While HID bulbs burn out, LEDs simply degrade very slowly over several years. In other words, an LED lamp may still be operational without supplying the light quality your plants require.
Why do new fluorescent bulbs flicker?
The starter is responsible for the momentary delay in lighting when some fluorescent tubes are switched on.
