It really doesn't take a genius to figure out that the light from the back of the bulb would be wasted without individual reflectors.IR's also helps the light penetrate better.
The Grimreaper(and maybe even Sanjay) has some PAR test and pictures of what each T5 bulb appears like.Overall,ATI had the best PAR followed closely by UV.Other bulb manufacturers had good PAR in certain bulbs,like the GE6500k bulbs.
