In previous years, I used a fluorescent fixture (with T5 bulbs) as a grow light for my seedlings. This year, I’ve tried an LED grow light — partly just for the sake of comparison.
I wish I could say I’ve seen a difference, but so far, there hasn’t been one. I can assume there is an improvement as far as energy efficiency. However, since the scope of my gardening has increased, the old T5 unit is still in use. Thankfully, a pair of fluorescent bulbs would hardly be capable of exciting the electric meter to where the house might be turned into some sort of residential equivalent of Airwolf.
All in all, the LED light works fine, I’m just not so sure that a modest increase in efficiency is worth having to endure the harshness it brings.
