Looking for advice on driving 3w and 1w LED's

Grumpy_Mike:
I would not bother about the length it is short enough.
Mind you it will radiate like stink but then you are not going for FCC approval are you.

I hadn't thought of that... like a giant antenna... hrm... any ideas on preventing that?

Shielded wire...?

I will use my SDR and experiment and see if I pick up any odd frequencies from using the lights as is... Mainly RC airplanes have lights so I am not thinking it's going to be a big issues, especially as long as they aren't messing with 433MHz or 1.3GHz hehe.

A question... I am using these cat4101 constant current sink drivers, and I am wondering... SINCE it is constant current, does that mean if I parallel multiple LED's to the driver that each LED will just get LED Count / Current Sink ma of current? Technically having the LED paralleled means that each LED will see 5v, and the sink will only sink 700ma total as that is how it is set, so if I parallel 2 white LED's that at full power consume 700ma each with a forward voltage of 3.5v onto a 700ma sink, then it should in reality split equally the current allowing only 350ma through each, and dissipating 1.25v x2 to heat (.5v is used by current driver), and continue the pattern regardless of the number of LED's... am I correct in my understanding, and or is there more to understand exactly how I would figure it out properly, thanks!
