^ cool. thanks Weez. Inverse square law, eh? gonna search that now.

yeah, after I thought about it a while I started thinking about some of the very same things you just mentioned. maybe wrap the lights around the outside of them, like on a circular fence not actually touching them, for a little added umpf down lower. but, I'm thinking now maybe you need them somewhat proportional and reflected to get the correct wavelength. :stoned:

but you are right, a little R&D may needed at this juncture. :jointsmile:
