Left you a rep comment in the other thread.

The last decent commercial light that I saw, was made by Lumigrow.
Can't pimp it, because I haven't used it.
But reviews and side by sides are very good.
And they are still around!

If I was in the market, and had any cash, it's the one I'd try.
I do endorse the science of it

Aloha.
