Plexiglass Reflectors for Flouro bulbs.

Im looking into making some portable Daylight Flourecent softbanks using common daylight bulbs from one of the big box DIY stores. I have two questions for any DIY-ers out here.

1. I found plexiglass Mirror panels available at my home center, they are super clean and come without flaws in the reflective surface. They are also very flexible. Rather than buying a highly polished chromed aluminum reflector for 10 or 20 bucks per light. I thought these might work. Has anyone used these or thought of using them for low/no heat lighting reflectors?

2. I have some Aluminum Ductwork tape used for high heat areas. Because it is pure aluminum, even the sticky side is quite reflective. I had thought of wrapping this around the backside of a flourecent bulb to create a self reflecting bulb. Am I wasting my time?

For what it is worth, I have used the aluminum tape in the past. It can be peened out easily to create a light diffusing reflector surface. in fact, you can simply use your favorite Manufacturers reflective surface (IE: a lowel tota light reflector surface) as a mold by sticking the tape onto some foam core, then take your manufacturers reflector material, land push it into the Auliminum-on-Foam Core surface you just made. A rubber hammer will work wonders for pounding the pattern into your foamcore/aluminum tape material without damaging your pre-manufactured reflector.

Whalla! instant peened diffused reflector. This concept is Similar to doing gravestone charcoal rubbings. Keep in mind, this application is for LOW HEAT light sources. Dont put a 1k tungsten bulb anywhere near this and please, do not try to re-sell these home made reflectors. The manufacturers put alot of time into the R&D end of these reflective patterns, some may even be patented!. Be respectful to them. There is a person on an assembly line or in a lab, that is behind the design of everyone of these patterns. They have to put dinner on thier plate everynight too.

Hope this was useful for someone.

When I made my original DIY 6x55 units I just used corrugated steel roofing for the reflector unit. Not perfect but not bad either. Later I determined the simplest solution was simply to use the plastic variety of corrugated roofing and coat it with 1mil reflective mylar plastic sheeting. it's far more smooth than any of the other solutions.
