Thread: Will the US 2.0 support a cree xre led?

    Default Will the US 2.0 support a cree xre led?

    Thinking of installing a US 2.0 in a Saberforge hilt any ideas if it will support the cree xre led? (I know it's not listed on the specs, but I figured I would ask).

    How can we be expected to think outside the box when we work in one?

    Yes,

    The XRE Forward Current spec is 700mA Max for Green

    And 1000mA For Blue, Royal Blue and White

    Both have a forward Voltage of

    3.5V @700mA

    Blue is 3.7V @ 1000mA

    Use the Lux III Setting for Blue, Green, White, and the Lux V setting for Green

    heheh, this is a prime example of why it would have been better to specify CURRENT target values in the USv2 setup menu, versus specific LED brands.

    I mentioned this back in the USv1 days (as did others), but... I'm pretty certain it was deemed unimportant or just not much of a high priority due to all the other clouds that were hanging over v2's release!!! :P
