Thanks for the reply. I'm planning to drive with 6 AA batteries (7.2 V). It's been recommended that I use a constant LED driver instead of resistors. I found several 3W drivers rated for 3W LEDs powered by 3-12 Vdc, but I can't find 1W LED drivers that can be powered by anything below 12 V...

I have a project with two, separately wired high-power LEDs. LED #1 is a 1 watt LED rated at 3-4 Vdc at 350/700 mA LED #2 is a 3 watt LED rated at 2 Vdc at around 350/700 mA According to Resistor calculations, I get: LED #R1 = 4.7 Ohm, 2 Watt rating (for 700 mA) LED #R2 = 8.2 Ohm, 4...
