I'm pretty sure Hara did the LED moonlights.

My question is why do you have to use a 12v source as long as you compensate with the resistors. Why not use the source for your walkman or any small electronic battery powered device. They come with a converter. My only problem is they do seem to get warm.

using a 12volt source allows you to use longer wires and run more LEDs.

the lower your voltage, the greater the loss incured over a wire of X feet and X gauge. so 12 volts would be more efficient over a 6-10ft piece of wire than 3volts.

edit:

I just read that link, and although it looks very nice, what could be the advantage of using so many expensive LEDs as opposed to a simple 13 watt daytinic bulb for a nano reef or a 250 watt MH for a major reef?

the 100's of leds required to light a 55+ gallon tank would cost a fortune, not to mention all the time spent to solder each one into that grid contraption. Even if you didn't have to replace the bulbs for 5+ years, it still sounds like too much work for too little payoff.

** neat article however - thanks for sharing it.

I've also heard of people using blue rope light that you can get at Lowes or Walmart.

ahh, the rope light rumor

-yes- one could use rope light, but then if going that route, why not just use a pair of those blue party-bulbs they sell for $1.99

the problem with this is the color purity of the light. rope light and party-bulbs produce light of about 2700-3000K (via tungenston filament). So you take this predominately red/yellow light, and put a cheap blue filter over it.

The result is very little usable blue light, along with plenty of red and green, not to mention a considerable amount of heat.

LED or neon moonlights produce light using a more advanced technology, and produce it a lot more efficiently and precisely.

Go to an auto parts store and look for neon accent lights ... this is what I currently use for my 30 gallon and they work great ... I have 2 11" bulbs taped inside my light fixture, and they light the tank almost too well.
