Yes mine will squash a 400w HPS grams per watt all day long. There is a 3 year warranty.

I see, company owner, quite impressive.
Can I get measurements for the DH 300 Watt LED.
How would you compare that to something like this

Is there a warranty on your LED's. Can your 300w LED replace a 400w HPS.

I own the company. We use 2 Blue wavelengths, 2 Blue wavelengths, along with Orange. We are the only ones doing this and are having fantastic results. There are people on this forum using my lights. Tdooda has a 90w UFO grow going right now.
