Re: [APD] AHSUPPLY's Reflectors

Hi and thx everyone for their responses about the Ahsupply.After a short study on the subject, here's what I've come to understand
so far. The curved surface only works if the focal point is used as a
point of origin. It should give back a more or less a uniform light
distribution from it. The focal point is fairly obvious and easily
calculated with y=sqr(x)/4p, p being the focal point. It's a good idea
if it does in fact give back the %65 gain over rectangular reflectors as
stated at ahsupply. I for one cannot see why it wouldn't. However, as
you step your light source out of the focal point, you start to loose
the benefit and hinder it with bounce back. So, trying to cram in more
bulbs into a parabolic reflector would effectively jam it up and put it
back on par with a rectangular reflector. I would even be willing to
bet on the smaller the source, and the more accurately placed, the more
efficient the parabolic effect. On the other hand, the limit to
effeciency gained by placement would have to be defined by the diameter
of the curve and size of the litght source.
But... Has anyone tried their reflectors with lights other than the ones
supplied with AH Supply say t8,t5's t12's?
Do you think it'll work since the cost is pretty good considering a 36" ish
reflector from Ahsupply is $20 USD + shipping, I really can't find any other
reflectors for about that price.
But is this reflector for one tube or can I use it for 2 or more t5 tubes?
Of course, when everything is said and done, just play with it and see
what you get. *grin*
