Very cool idea. I'm interested to see how this turns out. 12 volt fish lights

Upon research I've found 20w of xenon equates to about 120 lumens par with cp and t5. I've found a 110v 5 bulb model 70w per bulb about 1500 lumen available 6000k-18000k now I'm off to see how many lumen a 125w mh produces lol

lumens and par are not quite the same for corals

i dont know why you would want 12V lights, you would lose efficiency as the power supply would lose efficiency as well as the efficiency of the lights and you would need larger wire guage as lower voltage draws more current for given watts.

In case you missed it I found a 110v model not 12v i've found a house variety for 60$ 5 bulb unit,emailed manufacturer who says bulbs available in the kelvin range im after though they cost extra. The reason im pursuing the xenon h.i.d is its suitability for a nano reef because;less heat,less size,1/3cost to buy and cheaper to run than halide and the car variety are water proof. Seems too good to be true so.......
Im watching a post here where a fella plans to use the car variety on a 5.5g nano.....but he's taking forever to update lol

Lighting efficiency has a lot more to do with what goes on inside the actual bulb. LEDs are low voltage DC devices too and they are more efficient at producing light than fluorescent fixtures, MH or bulbs with filaments. Not sure of the principle behind xenon, sounds like a gas type deal like neon or fluorescent. I do know xenon arc bulbs are used in high intensity searchlights for aircraft and they can burn a hole through concrete if left shining in one spot for any length of time. Most bulbs still produce more heat than light with the current they use. That's where LEDs are a little ahead of the game. I suspect that if xenon was a viable technology for aquarium lighting, some intrepid engineer/company would have designed a fixture by now.
