Help modding a proton pro please

Photon Joe · Sep 20, 2008

Does anyone know where the Proton pro unscrews so that you can get at the back of the board ?
I need to do an LED swap and can only get the part with the lens/window off, and I need to get to the back side of the board to desolder the 3mm LED and replace it with a white one.
My eyes are not good enough to discern where it comes apart.
Any help is appreciated, thanks.

The Red And White LEDs Vf Are Different

Red=1.8–2.1 V

White=3.0–3.6 V

Vf is the term for an LED's forward voltage. Forward voltage is the voltage required to activate an LED. For example, if you want to power a Cree XR-E at 150mA, it needs about 3V. If you want to power it at 700mA or thereabouts, the Vf will rise to about 3.8V. It's like a minimum activation voltage for particular currents.

Thanks for the info. Some one else has already done this mod and it is working fine for them, so I want to try it anyway, nothing ventured nothing gained.
The LED's I have , have been running on one Energizer 371 cell .
I scavenged two of them from a small keychain light that has a (probably worthless) crank generator built in
connected to the 371 cell and the two LED's.

Ok , I found what I was looking for with the help of a jewlers loop.
Works great as a very low low that is white and ramps upward : )
Now it is all the light I wanted it to be.
Special thanks to Flashcrazy .

Ok, so what's the secret? I may want to do the same to mine.
