Have a question about MH

Ya, that is a little underpowered for that size tank. Still would work for softies and some LPS corals, but I would recommend a 150w if you wanted to do SPS corals. Also, it is harder than normal to find good quality 70w MH bulbs.. most good aquarium bulb Mfg don't make bulbs in that wattage.
 
I thought its the 150w MH unit double ender...?

And hell yes on the Hamiltons! I picked up two of those but moguls..and I couldn't be more satisfied. I just noticed a good color spectrum out of those 14ks vs my old 14ks..

Its odd when you try differ bulbs with same K ratings....some have more blue some have more white... Hamiltons have the light blue hue just perfect. well for me it is.
 
Wattage has nothing to do with the color temperature of the light. You can get 70w and 150w bulbs in different color spectrums.
 
Hm... i really just want to get a new light for my tank... A nice MH. :)
 
You may want to look into assembling your own fixture. Try looking into making a pendant with a nice reflector. The Lumenarc mini and Lumen Bright mini reflectors are small, but very effective at punching light into the tank. It is a more expensive option, however. If you want to stick with a fixture, try looking into the previously suggested Current Sunpod fixtures.
