Can I run two LED's off of one driver?

I'd like to build a set of navigation lights for my kayak and use one driver (with strobe/SOS functions). Given the fact that red and green LEDs have different amperage, volt and resistance specs, is this possible?

Here are some specifics on the components I'm considering using:

3W LED Emitter on Star (Multicolored RGB)http://www.dealextreme.com/details.dx/sku.4530

Red: 2.5V ~ 3.0V, 350mA
Green: 3.2V ~ 3.8V, 350mA

Driver 3W/5W 20-Mode 3x7135 Regulated Circuit Board for Flashlights http://www.dealextreme.com/details.dx/sku.7879#open full view

I understand the basics for connecting one led to a battery with the proper resistor, but when you add two different LED's with a buck/boost driver, I'm lost. :duh2:

Thanks guys,

Erich

Can anyone suggest online resources to learn what I need to know to build my project? :wave:

I'd really like to make sure I'm on the right track before I buy the parts and burn up two LED's or a driver.

Thanks!

With the right driver, you should be able to.

Just resistor them so they have the same relative Vf. The green operates in the same range as most white LED's so a 700mA 3.7V driver you'll need a 2.3ohm resistor in series with the red led, then parallel the green led with the red led resistor pair.

If you can find one a driver that puts out more than 7V at 350mA and just use the proper resistor to knock it down to ~6.7V and wire in series.

I would use a Bucktoot and simply wire the LEDs in series. I've assumed your power source to be between 5V and 24V.

First off, thanks for responding guys. I've been waiting for someone to come along! :wave:

I think I follow your suggestion, but what if I can't find a 700mA 3.7V driver? I'd really like to use a driver with the strobe/SOS feature and so far the only ones I can find put out 1000mA

I'd use that in an instant, but it doesn't have a Strobe/SOS feature.

Keep it coming guys! :thumbsup:
