yeah it looks like series to me, but leds have a life of 10,000 operating hours or about 417days of 24hr use. so if you only use them for 8hrs a day it would last for about 1250 days or about 3.5 yrs.

I put a switch into the line and the led's burned out. However the link to the site to get a new setup isn't working. I have bought LEDs and resistors from another site but i keep blowing the LED's. I need to know what size resistors to get with my LED's I'm using a 4volt output power source. and I only want 4 LEDs in the string.Any HELP will be greatly appreciated.

Great write-up. If anyone is searching for another online vendor of led's (ledwerx.com isn't working as far as I can tell) try eled.com

I ordered from there while I was deployed to Iraq and they were great. You are looking for 5mm blue (470nm) water clear led's. Click here for the page

Remember the higher the mcd value the brighter the output so you are most likely going to want 1000mcd or less. It is up to you though. Oh and JProx I have some of these high output leds on computer that have run 24/7 for years and are still going strong.

Also wanted to add the possibility of using a PC cold cathode kit. Since I love to mod my PC's this is a very simple moonlight anyone can do. I found this link that gives good info on it.

P.S. While you guys are at it change your opto mouse led to BLUUUUUU too! [/url]

I put one together also, but instead I swore I wired the resistors to the positive leads of each LED instead of the negatives. ????

the circuit will work in either fashion, attaching the resistors to either polarity will not harm the circuit, however they 'should' be attached to the negitive side (or shorter leg of the led)

Even though i have a freshwater tank, i put a single blue LED attached to a 3volt transformer from an old rechargeable shaver. Its the perfect voltage and output for an ultrabright blue LED. I have that, and a UV led into my tank, When you first turn off the lights at night, the blue strip from my neon's is VERY bright. Its quite cool!

Is having a weak moonlight in a FW tank ok?

up to 600 mAh sustained 1000 Mah burst. Got it for 6.99, it does 1.5-12 volts (pretty nifty)

DYI MoonLight LED Project

I was wondering if it would be possible to give us the type of resistance ( ohm) or the color rings on the ones you used in the project. I can go to Radio Shack and get some. I can;t quite make out the color , looks like White, gold, green, black, red, brown, and gold.????

Great pics, which my tank will look like that... maybe soon it will.LOL

Thanks in advance.
