Eggcrate question

[Troy F]

Here is what Dana Riddle had to say on the subject:

Troy,

Eggcrate was designed for use in luminaires, usually fluorescent lamps in elevators and the like. The holes in *some* eggcrate are beveled and this will actually focus light with point light sources such as MH lamps (though it will not for fluorescent lamps). I'll have to look through my notes, but I believe if the "thin" side of the eggcrate is installed upwards, you'll see focusing occur. I haven't tested eggcrate under MH/fluorescent combinations, so I can't really comment about the overall effect. It certainly won't increase the amount of total radiation, and I suspect there would be an overall, though relatively insignificant, loss of light. But if you want to focus a MH lamp into a deep aquarium, there may be some benefit.

Maybe we should run a couple of tests Darren. It could be interesting. If Dana is right then I just have to overcome its tendency to sag.
