Really? Thanks, The only problem is that my light doesn't take MH bulbs and it would be MUCH cheaper to just get the conversion bulb. If an actual MH not the conversion will make that big of a difference I will just spend the extra money and get another light for mh. So will it make that much of a difference?
In the long run a separate fixture would be much cheaper. I got a 400w MH high beam new with bulb, reflector and ballast off eBay for about $90 including shipping. One 400w MH conversion bulb (360w) alone runs that much.
