yes

if it doesn't just put the old one back in

no, kinzu LED is too weak, so it will decrease performance alot!

i can confirm that the LED's from diamondback 1600 and zowie mice work.

you might wanna check current/voltage for the original LEDs in both mice.

chances are the sensor is very much calibrated to the LED it shipped with, brightness, spectra, etc. unless your ready to blow alot of money on LEDs and potentially mice, chances aren't good you're going to simply change the LOD by swapping lights.

do post your results though

e: iirc LOD is a function of the lens over the sensor
