Lux3 - Vf @ If of 350ma or 400ma?

StoneDog · Jan 26, 2004

Has anyone measured the Vf of a T??K or S??K at 350 or 400 ma? Lumileds rates their Lux3's Vf at 700ma... I'm wondering if a Lux3's forward voltage isn't closer to a "J" or even "H" rating at lower currents...

K voltage bin at 700 mA can be J voltage bin at 350mA as far as I know.

You can estimate this from Forward Current vs. Forward Voltage graph in Lumileds DS45 datasheet. I actually measured a few and saw about 0.2 V drop.

Along those lines a "J" voltage Lux3 is probably a "H" at 350ma...

Thanks kj!

If it is Luxeon III of "H", does it become "G"? /ubbthreads/images/graemlins/tongue.gif
