Had 2 viparspectra in a 4×4 tent. 1 driver burned out. Not much luck getting it fixed. So my local shop had one in. I tried it. WOW! Huge production. Thanks guys for an outstanding product.

I run 2 sf4000 in my 4 x8 tent and love the results. Always tight hard nugs and never any issues. Spider farmer lights have been worth every penny at an affordable price. Now if they could just come out with extension cables to mount the drivers outside the tent it would be the best light ever and 5 star as it creates quite a bit of heat having the drivers in there.

I love the build of this light! One of the best in the market! Great little 450w light! Performs as well as m
A single ended 1000w MH for veg so far. And can’t beat the price anywhere. Other named brabd lighting is overpriced. It’s all made in China anyway. Just order direct. And save hundreds of bucks.

Could not be happier with the professionalism and fast service of https://spiderfarmer.ca/. Originally ordered the the SF-4000 LED grow light from a 3rd party re-seller. Didnt get an order confirmation or tracking # for over a week. Cancelled the order, and bought directly from Spider Farmer. They had the light on my doorstep in 3 days. Solid packaging… Proper light.. Thank You Spider Farmer.!
