    All you need are a couple of drop-in modules for 501B/502B styled lights. Also called p60 drop-ins, they ofen have the diameter (26.5) included in the title. 


    You can look through these.  >  http://www.dx.com/c/lights-lighting-1399/flashlights-1307/flashlight-parts-1374/drop-in-modules-1377


    There are different brightness levels, different tints, smooth reflectors vs. textured reflectors. 


    If you need more help, just explain what you need, or want to use them for, and someone here should be able to help. :)

    sku.386525 should be bright enough, but will probably get hot. 501B/502B style. lights are not good at dissipating heat from the LED. A drop-in with more modes like low/high or low/mid/high can not only make the light run cooler by switching to a lower mode, but also make the battery last longer. 


    There are videos on youtube showing how to wrap aluminum foil around the drop-in for better heat transfer though.


    Concerning batteries, if the specs are accurate for that drop-in, it uses 3A current. That means you'd need a good high capacity battery like a Sanyo or Panasonic. Stay away from cheap batteries like Ultrafire or any batteries with stripes on them.


    edit - Btw, protected batteries are a good idea. If you run non-protected batts too low, they may be damaged or killed completely if they get compltely empty. Protected cells will shut off before that happens, and also can't be harmed by over-charging, possibly from a poor quality or defective charger.

    Wow! sku.396525 is hot! But I don't like the tint. It's too yellow. LOL

    What's up with the scrubbed LED driver IC markings?
    What are they trying to hide?

    It's a single cell torch, so you should use a Sanyo 2600 mAh cell, like sku.121447 which holds a higher voltage under load.

    When I first started posting here, I'd often get quite mad when people didn't even bother acknowledging any help I (or anyone else) offered. I thought it was ignorant. 


    Since then I've realised that there might be a lot of legitimate reasons why people don't always say thanks, or tell me I was wrong and I'm an idiot, or say anything at all.


    Once in a while (if it's something that really interested me) I'll ask a month or 2 later if they've solved the problem, like you did here, but not a year + later. lol


    edit - Weird!? In the first sentence of my first reply, I wonder what possesed me to say a "couple of drop-in modules"?
