pic of my diy moon lights

are these units made with 12 volts DC?

if they are and u want a power converter use an old pentium 1 power suplly with a switch on it <the red wire is 12 volts DC and the black is yer earth on the hard drive and cd rom plug>

... if i was gonna make moonlights id go that way about it 8)

 

Can you possibly give us a close up picture of the layout?
How you have it set into the fixture would open our eyes more so?

Thanks from the newbie

let's see some pics!!

 

I was thinking of using LED Christmas/rope lighting.

 

Dont you need some kind of resistor to un LED's? i was going to use an old 4.8V DC charger to run a pair of LED's i found at the radioshack here in town that are 430nm. could i just wire them from the charger to the LED?

 

WOW, Thats only one led light and it lights up the whole tank? cool beans!

 

you need to current limit the led's with a resistor or they will overheat/burnout , lots of led scematic charts on the web a resisters are dirt cheap just plug in whatever voltage you want to use ie: 12 v / 24 / 6

 

I know that, But....say i have 6, 2 watt LEDs and i plug all into a 12 VDC cconverter, would a resistor be necessary?

 

always need a resistor to limit the current otherwise they will heat up and flow to much current even if you had 4*3 volt led's w/12v p/s in series you would need more than 15 volts so give em more than that and limit it with a resistor or run 2 banks of 3 leds series / parrell w/resistors to make up the 3 volt diff. 3*3led=9v + res 3v=12v must have resistor inline to limit ma.

 

Gotcha, i think
