I have an sf4000 and an sf2000. I love both of the lights they are great for personal at home grows. Easy on the electric bill and still produce big fat frosty buds. I have many lights from many brands but spider farmer is the only one I have bought more than one of. Best bang for your buck I believe!

I ABSOLUTELY LOVE THIS LIGHT!!! For about a year I used the sf1000 and loved it so much I upgraded to this BEAST OF A LIGHT. The trichome production and canopy penetration are absolutely insane. This light is a must have. Highly recommend for new or novice growers. You won’t be disappointed.

Hello,
I have two of these sf4000 as well as a sf2000. The sf4000 is amazing. I went from hps lights that drove up the electric bill and added unnecessary heat problems to these. They are so much better. These sf4000 lights have been an amazing replacement for my 600watt hps lights. I hope to get another in the future because I especially like the daisy chaining ability they have. That you for your great products. I will continue to use your wonderful products. Thank you
