    I can’t say enough good things about these lights! I always grew microgreens under AgroBrite T5 fluorescent grow lights (6400K) because I could never find an LED that was as bright. I tried many brands of LED’s and my plants didn’t like them. The quality just wasn’t there. I finally came across HTG Supply and found these lights. What I was immediately drawn to was the fact that I could replace all my fluorescent tubes with these and not change the fixtures. That was a huge plus and saved money. So I ordered some and quickly noticed that these LED’s were brighter and better than the fluorescent bulbs. They’re amazing. My microgreens look as good as ever, we save energy, lower the heat output, and I’m thrilled with their performance. These will last much longer than fluorescent tubes. I look forward to replacing all of my lights with these. Since I have a business, I really needed a solution that would hold up for all the use they get every day and still give me great results. Problem solved! I’ll never use another light now.
