Think I found my new light. 400w air coolable, digi ballast hps. My current light hasa magnetic ballast which is also mounted inside the hood and gets a bit too hot for my taste. Anyone know how many cfm's I'll need to sufficiently cool this? I saw some inlines on the bay anywhere from 150-500, i was thinkin more in the 500cfm range but hell idk, LOL. Here's a link, lemme know what u guys think
