I believe these have the same reflector that comes with the SLS's Tek and New Wave fixtures. It's a single piece of alumium that contoured around the bulbs so you get many of the benefits of the individual reflectors.
I take that back. Based on the dimensions, it appears that the Sunblaze does not have the contoured reflectors. Check into the New Wave. I have one so I know for a fact that they come with the same reflector as the Tek fixtures.
