Sadly the LED option is fixed for various reasons which have massive time/cost issues. (aka I didn't actually think providing reliable power to these LEDs would be troublesome before I fabricated the LED mounts, lenses & bezels which are part of the fabricated and now powder coated frame....)

Thanks for your reply Onoff. I have had them running with resistors (15R 7W) for testing, but even at 700mA its around 7W of power dissipation which would concern me in itself (for reliability), but with the pulse current going up to 1.3A or more that would be 25W++.... I can't see the resistors...

Hi I have been scratching my head over this one - first time posting on here, so "hello"! What I am looking for is the *best* solution to provide 2.4V DC at 700mA to a high power LED from a 12V DC supply (motorcycle indicator in this case). The spec' of the LED is:- Max Forward Current...
