Depends on what is being grown.

Are you selling LED lights? Please, no spam for me. I'm using forty year old shop lights for my seedlings. This year was the first year I replaced a ballast. I throw away LED Christmas lights that were four years old. HALF were burnt out. Yes, HALF! I'll put my Swedish Christmas Candle lights on my Christmas tree against any of your LED lights. We have replaced three bulbs on the 32 original lights in forty years. One hit the tile floor and broke. Bah Hum Bug!

I'm not sold on any new technology until the quality comes up. Everything says made in China and the price is cheap but the quality is not there.
