    Default JIL-CR2 1.3W with Goldserve's Piglet driver and Seoul P4 LED

    CPF member Goldserve has developed a mod for the JIL-CR2 1.3W (and JCR2-HI) to allow them to use his Piglet 2-level, buck-boost driver with strobe, beacon, and SOS functions. He is also upgrading them to the Seoul P4 LED. He is currently making one for me and one for himself (and may have a couple of extra holders). Here are some pictures of his:

    2 - Piglet goes at one end


    3 - LED goes on top


    4 - back of the head


    5 - front of the head


    6 - front with reflector and bezel installed


    7 - tritium insert


    8 - tritium locator in the dark


    9 - finished light

    Here are some pictures comparing a 'stock' JIL-CR2 1.3W (with TW0H Lux-III LED) to the goldserve-modded JIL-CR2 1.3W with Piglet driver (50mA Low / 500mA High) and USV0H Seoul P4 LED. Both lights are using CR2 3V lithium primary cells (not Li-Ion cells).

    -----------------------------------------------------

    Here is the Piglet driver using the 500mA High setting to drive the USV0H Seoul P4 LED:

    JIL-CR2 1.3W (TW0H Lux-III) [Left] vs. JIL-CR2 1.3W with Piglet (USV0H Seoul P4 at 500mA) [Right]
    Exposure Compensation 0


    Exposure Compensation -2


    Exposure Compensation -?


    -----------------------------------------------------

    Here is the Piglet driver using the 50mA Low setting to drive the USV0H Seoul P4 LED:

    JIL-CR2 1.3W (TW0H Lux-III) [Left] vs. JIL-CR2 1.3W with Piglet (USV0H Seoul P4 at 50mA) [Right]
    Exposure Compensation 0


    Exposure Compensation -2

    (that's all for now)

    Thanks for doing this vortechs. Very busy with building a few converters, etc.

    I've been waiting for the 1.3w to be upgraded!

    Any idea on price yet?

    I can sell the module with the seoul led but you still need to remove 0.015" off the back of the reflector to get perfect focus like mine. Since I only have two left, I',m thinking $65 for the complete module without the reflector.
