Thanks for sharing your experience with the plant light. Azo is primarily sensitive to light in the near band UV range. It's peak spectral response occurs at 350nm and drops from there to appr. 460 nm. Most of us use reflector floods which have virtually non existant UV outputs and the output from these lamps that is higher then blue is largely wasted. So your plant light is probably much more efficient. The lowest wattage that I have been able to utilize with a reflector flood is 150 watt (Pyrocat HD negatives) and more normally 300 watt (with ABC Pyro negatives).

I would appreciate it if you would share your experience in that regard when you have have had time to evaluate it.
