Actually changing the current is easy for me.
It's opening the stupid plastic welded-sealed PSU that's the hard part. :-(

Figured out how to open... silly screw behind label.

Now... this PSU is awful... very inflexible CC. Seems like it's CP (constant power) and not really CC.

Now I wonder, how long will a 1W LED last if I drive it with this PSU that I think will dump 2W into it with the easiest mod I can think of... else I'll have to think about how to incorporate multiple LEDs without a heatsink as I can't use the existing aluminum star with two LEDs...

Oh, nevermind, came up with a better solution, can drop down to 1W. This might end up in the worthless repairs thread, and might also qualify for ghetto mods
