MH conversion bulb can operate on a 400 watt HPS ballast which is what I'm selling.
Yea I didnt have the money/didnt want to spend the money for another ballast so I bought the conversion bulb. It worked pretty **** good, the box says it puts out 38,000 Lumens.good stuff. IIRC , it wont put out as much light/lumens as a standard MH bulb would but nonetheless , its does come in handy. especially if you dont have the cash for another ballast. i would snag this up but i cant do anything with it ATM. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
