+mcallahan Posted February 28, 2009 Share Posted February 28, 2009 I'm about to upgrade to 2x250W MH, and I'd like to get an idea of how much the increased wattages from my 175's will raise the temp in my 90. Anyone got some 250W bulbs laying around they'd like to get rid of? Of course, something newer would be best, but not nec. req'd. Link to comment Share on other sites More sharing options...
princer7 Posted February 28, 2009 Share Posted February 28, 2009 I've got 2 bulbs that I keep for an emergency that you are welcome to borrow. Assuming you need them to test with. Link to comment Share on other sites More sharing options...
