Lighint, reflectors: painting tubes
I just bought some URI aquasuns and these have 'built-in' reflectors.
The top half of the tubes seem to be 'shaded' vs reflected. This got me thinking, and I was wondering what would happen if the top 1/2 of a tube was painted? Say in a silver, or a white colour. Would this not be a good thing? Anybody have a light meter (a lux meter) and an old tube that they would be willing to experiment on? 4pts...

What kind of paint were you thinking of using because the bulbs would get quite hot.

I thought those bulbs had internal reflectors (shiny bit on the inside), not external ones? The idea is to send all the light downward not block some of it from going upwards. Why not just slap a chunk of aluminum foil behind the bulb?

That's exactly what i am talking about.
Don't think it'll work? I know that white paint is recommended as a reflector. I know the best solution is a set of real reflectors. I can really do it as my layout is like this --------*****4''NO***** ******4''NO****-------- *****72''VHO********* *****72''VHO********* --------*****4''NO***** ******4''NO****-------- *** being the tubes and between the 72" is the hood hinge.
