This is my first proper grow light. The price was well below other suppliers. The delivery was a few days later than expected however it wasn't an issue. The light at full strength was a bit too high for my GG auto. I lightly burned some upper leaves. It took some time to adjust and get set to the correct height. Operator error not the light. The plant is now responding very well. All in all I'm very pleased with the product and the entire process from order to delivery. Thank you!

This is a really great light for a number of reasons. Build quality and packaging are great. The light quality and output is exceptional and perfect for a standard 2x4 size but honestly can cover 3-5 or expanded with a second light to cover 4x4 well.I could not go back to a non-dimmable light after this - you can start it dimmed and increase as the plants need for light increases without messing with the distance/height. Driver does get hot when set to 75%+, but it is movable outside your tent if neccesary.Additionally its worth noting that the driver ELGC-300-H-AB is oversized (or well suited) for 300w compared to say the XLG-240-H-AB (240w) that comes with the comparable SpiderFarmer SF4000 450W.

I've heard great things about this light and I'm looking forward to seeing the results myself.
Amazing! It works perfectly hitting every area as it says with perfect light. Super easy to instal and it looks so clean. I'll definitely be purchasing a couple more. Also the shipping was super fast!
Never purchase this item again
This model has the Less efficient lm301d diodes and no longer has uv diodes.. I wish I had I known this before I bought it.. maybe this should be called the sp3000e so there's no confusion
