Iwasaki only has a DE 250w 14k/15k. The advantage of the iwasaki 175w is that its PAR output is equal to (and in some cases greater) than a lot of other 14k 250w bulbs. You’re definitely getting more PAR from your 400w XM setup than you would from the 175’s, but the question is, do you really need that extra light with only 11” of water? Also, you could probably achieve pretty close to what you’re getting out of the 400w 20ks if you lower your reflectors down for the 175s.
