Why putting an IMR10440 in a regular AAA light is bad:
1. LED mounted on aluminum MBPCB/Heat sink. Aluminum sounds good but the LED actually sits on an insulator layer which doesn't relive heat from the LED fast enough when over driven with a IMR10440.
2. Circuit components are typically rated about 2V to boost max efficiency. When you put in 4.2V things goes into direct drive and all sort of things like transistors can overheat and go. Power=Current*Volatge, A linear relation, Upping voltage surpasses the max power handling of all parts and they will inevitable fail.
3. If the components do not fail completely their specs will change over time and thus you can not go back to AAA anymore.
4. LEDs life dramatically reduced due to unrelieved heat
5. LEDs can de-solder itself with heat
6. High heat at the LED = current inefficient flow = lots of heat = brightness loss. Current must flow smoothly to keep heat and thus resistance down.
Those are some reasons that came to mind.
DriverVN2 is user programmable making a AAA size light incredibly comprehensive but flexible. LED mounted on copper gets heat away from LED right away, no bottle necks. The more heat you feel is the less heat the LED have to suffer. Extra copper HS adds heat capacity. DriverVN2 has a great track record. Sold many hundreds with very little issues. And when there are issues its usually just my fault not the circuit.
DriverVN2 & DriverVNX2 are continuously being upgraded with improve parts. Although never officially announced.

I quickly checked inside my pocket and thankfully the light was there, but no sign of the clip.
