Which reflector would you recommend for a SE 400W bulb? Are the ones on most sites (BRS, Premium Aquatics, etc) all the same or is one better than the other?It is actually the reflector material that makes a HUGE difference. Good reflectors use high quality dimpled aluminum that is actually made in Germany. And the geiseman has such material in it.
The reflector material is soo important that commercial green houses typically throw the reflective material out and replace it every year instead of trying to get it clean.
Why ATI t5 reflectors put out soo much light... the reflector material. Anyways... nice fixture man!
