Can I upgrade the old p7 emitter in my MS 816 to a newer xml family emitter without changing the driver? Just want to squeeze a little more light out of the old girl.
sure, no reason why not. You may have to fiddle with the reflector a bit or how high the LED sits to get the beam right, but that's the only issue I can think of.
I did a couple emitter replacement jobs and found that as little as .5mm difference in the position of the emitter into the reflector made big changes in the beam quality. Too deep or too shallow and the beam gets halos and rings in it.
