Petzl Tikka Mod with brighter 5mm LEDs

godlight · Jun 24, 2009

I have a Petzl Tikka which i want to mod with brighter LEDs.

This Headlamp is powerd by 3xAAA 1.2V (=3.6V) rechargeable batteries or 3xAAA 1.5V (=4.5V) batteries.
It uses three unknown 5mm LEDs. I want to upgrade this Headlamp with 3x Nichia NSPW500GS-K1 5mm LEDS.

Has this done anyone before?
Can i just replace the LEDs or do i have to replace the resistor too?

Ok, guess nobody did this before.
Anybody knows something about the circuit in the Petzl Tikka? Which resistor (ohm) is used?
