Who it's not for:

Specifically for 315W CMH lamps — won't drive HPS or LED fixtures. Check your CMH lamp is 315W-rated; wrong wattage damages the ballast. Reflector and lamp sold separately unless buying a full kit. For larger grow spaces, 630W CMH (twin-lamp) or 1000W HPS alternatives provide more coverage per fixture. Not compatible with digital timer signal controls used by some ballast ranges.
