70 Watt Metal Halides???

[Coffeeman]

No, a worklight would not fire them, you would need a proper ballast rated for 70 watt Mh.I have seen several types for sale on ebay,aromatt is one,it generally sells for about $50.00 us,advance and fulham also make a ballast rated for 70 watt mh but they usually cost more,then there is WPI,they sell for less.The ballasts that I mentioned are all electronic ballasts, if you call albrite I think they have magnetic hqi ballasts but I believe they cost around $150.00.The bulbs are generally quite expensive too, I've heard the catalina bulbs at pet supply liquidator are garbage,the ushio are the ones to get,there is a guy selling them on nano-reef for about $50.00 us, otherwise hello lights sells them.Alot of people are using Regent light fixtures to house the lights,they can be bought at Canadian tire for about $15.00.The bulb would replace the halogen one and you would just wire in your own ballast.
