I just checked it out, looks good but any company saying that you can replace a 1000w hps with 400 watts is full of it. But for the price you could buy 2 and do real well in 4x4 or 5x5. Leds have come along way and we are just getting to the 10000 dollar for 4x4 range, most 4x4 lights are 1500 and up. Meizu or something like that have some good quality lights or so I've read. Meizu I think. I would try to stick to NA made lights. There are lots of led companies closer to home, better for warrantees. Hope this helps in yourr light purchase as it is an investment that should last 10 plus years

I ordered one. I figure it has to be better then the blurples I have already. So if it will grow me better buds then the lights i have now then it's money well spent.

They used to make cheap blurple lights...... Hard time believing those efficiency#s with a crappy glue? based conformal coating. Also 100% osram chips(uv excluded) at that price and draw isn't happening, even with lower bins.

Weakest link will be the generic drivers imo, hope it has a stateside warranty

Here from the future on a hopefully not dead post so I'm hoping you'll respond to how has the light held up over the last two years and did it show an improvement in your yield compared to your old lights.
