Am I going crazy or did Zoo-Med used to make a higher watt powersun than the 160? I seem to remember there being a 260 watt version? I was planning on using them in my new water dragon room, I don't think the 160s will cut it. Does anybody know where I could get the 260 watt powersuns if they used to make them? I did find a 275 watt Active UV bulb, but I can't seem to find a fixture that is rated for more than 250 watts. BTW, the finished size of the enclosure will be 11x5x7 if anybody has any suggestions.
