That is what I was looking for, but my next question is, is the manufacturer for the Lumanarc, Lumenbrite, Lumenmax line of reflectors gone?
The closest I can find is one seller in the UK, along with a Chinese knock off going under the same name.  Or the Hamilton brand of clones.  It appears I may be too late to jump on the tried and true method of lighting.
Also if I have read the intertubes correctly, as long as I use a single ended bulb I don't need a UV shield, just a splash shield.  Since this will be centered over my clam bed, and I'm going with Dersa and Squamosa clams splashing is a possibility
