"Lumenarc" Reflectors...

[banditpowdercoat]

but how many can be built form a sheet????? I may be interested in enough for a 175W reflector. Want to try MH on my corner tank, but want to do it cheap for starters, see if I like it with the heat issue and such

I think from that sheet I was looking at you can build at least three, maybe even four. I would have to double check though.

Each one takes up 21.5" X 21.5" so you could make 2 reflectors per sheet!!

Just a thought but maybe try some fabrication shops. I know I *could* get some mirror-polished aluminium through work but last time I looked into it the cost was... prohibative. Granted that was for 16ga and over a year ago though. Maybe try for some 20ga or lighter? One thing to keep in mind, at some point the price actually goes UP with thinner material.

There is also mirror polish stainless steel but again... not cheap. I'll double check what the technical name for that finish is and post so you can at least take a look at it.

Yeah its looking like the really good stuff would make this project more expensive than buying the real thing. So I have to look at materials and see if there is a cheaper product that has a good reflection and hopefully is relatively thin. We'll see.

There is one material I had thought about that is relatively cheap... I just have no idea if it would be better, worse or no change at all. Aluminium Checker Plate, it comes polished, is readily available and you can get it pretty thin. I thought *maybe* the checkers would be something like a hammertone finish only better because they are polished. But they could also just scatter the light. I've never seen someone use it so if you want to be a guinea pig...

I purchased original lumanarcs about 3 years ago. One of the most difficult decisions I ever made as I already had light reflectors on my system (not a rich guy!). However, after buying these reflectors, well one of the best purchases/decisions I ever made in this hobby. These reflectors are work every penny!
