I have a PARFACTWORKS®️ LED Grow Light BM1000. And I a BM1500 and Zeus 700 and a Horus all from Parfactworks.. All are great lights and I would grow with them again. I have the Bm1500 Set up in my 3 by 3 tent and the Bm1000 would probably be more then enough light for a 2 by 2... It's A/C Driven with no Constant Current Driver. But the plants don't care and neither does my Umol meter. Save some money get lights that produce without breaking your bank.
