Hugsby P31 Disassembly / Driver replacement / All flood MOD

In case you’ve ever wondered how to disassemble the Hugsby P31, here’s how it goes:

I did that because of a malfunctioning driver, and while i was at it, I’ve replaced the reflector with an all flood TIR lens. This makes the little Hugsby a perfect near field flashlight.

    Hello Sir, I’m trying to disassembly mine but I don’t know what is the next step from here

    Hi Ricardo
    You will need to remove the thing that holds the optic, it’s screwed on to the driver pill, and holds pretty strong, I’ve tried heating it up a little, but still wasn’t able to remove it without scratches. The part I’m talking about is the one on my last picture.

    Cheers, Nico

    Thanks for answering Nico, I’ll try it, I’d like to know if the correct direction to unscrew this piece is in the anticlockwise direction or reverse. Also, I am doing this because my flashlight fell from my hands and now does not lights but when it is on, it turns hot, do you know what may be the problem and where can I get the replacement?

    Thank you so much Nico.

    No problem, glad someone read my post. The threading is standard direction, so loosening it is anticlockwise.
    For a replacement driver you should search for one that has the right diameter, is suited for single AA operation 1.0v (or lower) to 1.6v input. Output should be arround 350ma, if I remember right.

    Cheers, Nico

    thank you again, I thing the broken part is the cree q3-wc because when it’s on turns hot but doesn’t light, this is the only cree q3 that I could find (removed) do you thing it will works and has the right diameter?

    The led itself should be the right one, but I’m pretty sure, that a 20mm Star (cooling thing attached to the LED) does not fit the Hugsby, as you have yours currently open, shouldn’t be a problem to check how big it can be.

    Hey Nico, here again… could you tell me please if I can use a different led like this with the same hugsby driver supposing it has the right diameter? Thanks
