COB 520 watts Grow Light Full Spectrum with Convex Lens 3 Dimmers Version 13 Band Including UV IR for Garden Greenhouse Hydroponic Growing etc Indoor Plants Seeding Veg Bloom (520W)

There are many other lights available that are much higher quality and a better value. After approximately 1 year of use two sets of lights went out. Contacted the company and they sent some miscellaneous parts with no instructions. Attempted to repair the light, but after 3 hours I found it best to toss out the light to avoid starting a fire. Do not buy anything from this company. You'll save yourself an incredible amount of time and frustration. Trust me.
