The Diamond reflector is a reflector specially built to concentrate the lamp's light.
With a standard reflector you usually get "heat spots" and spots that don't get enough light under the reflector.
This reflector concentrates the light evenly on a surface of 100cm x 100cm.
The bulb in the kit will work with all kinds of ballasts but it is optimized for use with the "superlumen" 10% boost.
The ballast included is an electronic one with four settings, 250/275/400/440W. This means that you could use 250 or 275W during the vegetative phase and then put it on 400W during bloom phase. To maximize your crop you can even boost it to 440W.
