A long time ago, when getting into the hobby, I bought a really sweet 48" fixture off ebay. When I got it, I found out the moon lights were on the same circuit the actinics were on so I sold it. That light had 2 MH pods, and they said you could put 150w bulbs or 250w bulbs in it.
Fast forward to now. I have acquired a used 46g bowfront on craigslist and I am getting ready to set it up. As I am looking at lights it has occurred to me that my tank has a center brace. This seems to be a problem as most 36" metal halide fixtures have a single MH pod...in the CENTER of the fixture Now if I could cut that center brace away with a dremel that would be perfect, but we all know that's a pretty bad idea, I think.
So I found this:
36" 3 ft Metal Halide T5 HO Light Aquarium Reef 656W | eBay
Now this sort of thing would be perfect for my particular tank, except WOW that's powerful. I don't want an algae farm, a 2k electric bill or a 95 degree tank, so here's my question (FINALLY!)
Can you put a double ended MH bulb of a lower wattage in a circuit that's rated for a higher wattage and have it work just like that fixture I had a while ago? Can I stick 150w DE bulbs or even (omg this would RULE) 70w bulbs? Safely?
If that could happen with the above fixture I'd be in heaven, and so would my corals. Otherwise I'm stuck with unattractive options like Viper clamp lights (that still don't give me actinics or moonlighting) or pendants (same issue). I really want an all in one solution, and both PC and LED fixtures are too expensive (in different ways). Any help would be appreciated.
