Unless the reflectors are made for T5's your not going to get the realbenefits out of the lights no matter how nice it may look. The one lfs here sold a heap of T5 lights and el cheapo reflectors made for other type tubes, and w hile it looke fine, it ws anot anywhere near as efficieint as it should have been. One person bought proper reflectors, and after a lot of bashing and tantalizing the shops owner that its a heck of a note to sell high end lights and cut corners on reflectors, he finally sprung the $$ for propper reflectors, and needless to say its like an entire new light system allover again. There is a diference in usuing the right reflectors......and not just a material or reflector for another type light.
