I’ve been using the purple color LEDs for about 5 years. The whole time thinkin I was getting the most bang for my buck....wrong! Quantum lighting is the way to go. Been running it for 3 weeks and can already tell a considerable difference. Super bright, adjustable, and very little heat. Like the title of this review states, I wish I would have purchased a long time ago. So stop just looking at them in your watch list and dreaming, just buy the damn thing, you’ll be more than satisfied! If not, you’ll be left behind by all of those who do.

This light arrived with out hangers and only half the board lit up.I was excited to see a “good light” for a cheap affordable price however it was to good to be true as the light came broken. They also wanted me to pay for a new driver and are doing everything they can to keep me from returning it.0/10 recommend

The very BEST money you can spend pondered purchasing other LED grow light but a buddy recommended the sf4000 so i took faith and so glad i did BIG yields also with the correct nutrients. P.S. Thank You Spider farmer for the dimmer knob addition, love it, its so easy to dim now for veg

I purchased the spider former 4000 to replace two 600 W high-pressure sodium’s my light bill was 500 and month and now it’s 360 my harvest I think will be better I have 30 days left and my colas are the same size as they used to be when I harvested with the two 600 W high-pressure sodium’s I feel this LED may not be lying when They advertised 2 1/2 g per watt consumption I think it’s a good product
