Game-Changing Full-Spectrum LED!

The Spectrum King is a real game-changer. We've tested numerous LED systems and, up to now, none of them have ever quite measured up. However, when we got our hands on a Spectrum King, it was enough to make us stand up and take notice. Turn this thing on and it's immediately obvious that you're dealing with something that's at least on a par with the best HPS systems in the industry. It's BRIGHT - incredibly bright! Initial tests have yielded exceptional PAR readings that maintain a good level of intensity even around the outer edges.

If you want your plants bathing in intense full-spectrum light, while saving money on electricity and dealing with heat issues, then you've just found the grow light you've been looking for!

This listing for is the wide angled 120° version of the Spectrum King 400+.
