Rick Posted July 28, 2009 Share Posted July 28, 2009 Does a 400w mogul base also fit a 250w bulb? How about 150w or 175w. I can't seem to find a site that reliably tells what bases are used for what bulbs. Quote Link to comment Share on other sites More sharing options...
chewie Posted July 28, 2009 Share Posted July 28, 2009 Mogul sockets are universal to 400, 250, and 175w bulbs. 150w is different. They use Medium Sockets. Quote Link to comment Share on other sites More sharing options...
Rick Posted July 28, 2009 Author Share Posted July 28, 2009 Great, All I need is a ballast and bulb then. Quote Link to comment Share on other sites More sharing options...
ThePremiumAquarium Posted July 28, 2009 Share Posted July 28, 2009 In my experience 150w-175w also fit in standard moguls. I had a few PFO 175w ballasts that I used the same reflecors and and moguls on that I had running on 400w ballasts just before. I know that DE are defiantely much smaller for the 150/175w but the SE moguls should be the same. Garrett Quote Link to comment Share on other sites More sharing options...
