I have tried many times each day since the day I got the product to register it with no luck. Is this so it has no warranty? That’s convenient for the company.

Ok so here I am switching to LED lighting and moving into a tent. I was using a 1000wt hps. for flower. I was skeptical,watched a few videos and took a chance. I picked the sf4000 for a 4×4 tent. Amazingly heat wasn't a problem. I decided to do a test run with one plant in a 20 gallon pot filt about 70% of the way with my soil mix I always use. Let me tell u my results with a plant half the height was crazy good. I totally recommend this light and my electric bill loved it. I became a believer. I'm actually thinking of getting the 450 to do a 5×5 tent.

I was skeptical to switch over from high pressure sodium lights in flower but this light made me a believer! I put one plant in a 29 gallon pot and let it do it's thing. The results where as if I was the utube guy giving classes on growing. My electric bill was hell of a lot lower and my yield on a plant half as tall was crazy good. Can't loose with this light and made in America!

I now have 3 of these lights. Sonofarm is an outstanding company, great service and great quality.

i needed another grow light and researched them all and found that the sonofarm was the best quality and price. this sf 4000 is very bright and well built, pretty too.i already have a mars hydro but this light is better quality and less money so you cannot beat sonofarm if you need a really good growlight and shipping was very fast , recieved it the third day after ordering/i am well pleased with sonofarm,and they are americans with great customer service,unlike the chinese people. thank you sonofarm
