That's really going to take some investagation and math to figure it out. Never exceed voltage or wattage stated by the product. Your best best is to contact the manufacturer. They will be able to give the final yea or nay. Good luck :watchplant:
A reflector is just a reflector (although some are better than others obviously) ... doesn't matter what size envirolite you are using, there's no ballast ... ya plug em straight in.
My 125 W envirolites fit my HPS reflector fine, same fitting too ! However my 200W envirolite won't fit into it, the bulb itself is too wide.. If it fits ... it will work.
