sharn Posted June 30, 2009 Report Share Posted June 30, 2009 We have a 1000W metal halide ballast here and I was wondering if you could put a 400W bulb in it without it blowing? 1000W is just a teency bit excessive for my 460L tank and if i can get away with not buying a whole new unit that would be fantastic :lol: Quote Link to comment Share on other sites More sharing options...
Ira Posted June 30, 2009 Report Share Posted June 30, 2009 Give it a try let us know what happens. Seriously, though, I believe the different ballasts provide a different voltage to the lamps. I can't seem to find any numbers, though, I think I've seen them before at some point. Quote Link to comment Share on other sites More sharing options...
Ira Posted June 30, 2009 Report Share Posted June 30, 2009 Ah hah, http://www.solacanada.com/ has some spec sheets for ballasts. Says the open circuit output voltage for 400w ballasts is 300 volts, 1000w ballasts are 410 volts. The operating voltage would be lower than that, but I think you can imagine why putting more voltage than designed through a lamp would be a bad thing...
