RGB hilt wiring

[neophyl]

Dont worry about reverse current. The important one is vf (forward voltage) which is the voltage you need to supply to light up the led.

ok, well...the red led is 2.4 volts, and the green and blue are each 3.4 volts. would i add everything together (9.2 volts)? or take the highest voltage (3.4 volts)?

[Hasid Lafre]

Remember the prolight led is a 3 watt bu tnot really. it has 3, 1Watt led wafers inside the one emitter.

So you would need to get a 1W resistor, which is why I said to find an mr board or and forgo the resistors, its easyer to have 3 power wires comming of the one power lead.

well, i'm pretty sure i'm going with a resistor set-up. i'm just wondering what battery i need to use, a 4.8v or 7.2 v. i'm guessing a 4.8v is fine. once i have that figured out, i think i'm ready to buy everything!

[Lord Maul]

4.8V is plenty for a RGB

[pthomas625]

ok, coolio. thanks!


EDIT: anyone know a good place/site to buy resistors? i looked in this shop and didn't see the ones i need. i don't think i've seen them at home depot. would radioshack have them?

EDIT#2: which battery charger do i choose?

[Hasid Lafre]

nimh the redone.

[pthomas625]

ok, thanks.

[Lord Maul]

radio shack will have the resistors for sure, so will any other major electronic store

[supertrogdor]

dont speak too hastily there Maul, not all radio shacks carry resistors. Granted i live in a small town, but it is an average sized radio shack compared to what i have seen in Salt Lake City, Boise and such, and they have almost no resistors. you can occasionally find a useless pack of several very small resistors, but rarely anything usefull enough for even the most basic electronic work.
