Would be cool if possible, and that would be the preferred method for proper LED dimming, vs pwm. But I'll take a version either way. If the constant current works then we could eliminate the buck pucks/drivers from our LED ligts and save a few percentage points if efficiency. And make building your own lights, or upgrading lights, mucho easier.
