    Finished my first light build

    Hey guys I finished my first light build the weekend but it seems I used the wrong switch because the light only works if I hold in the button. What I'm using 3023 BuckPuck 1000mA and 2 x Cree XP-G, I attached a picture of how I have it wired. What kind of switch do I need for this set up?

    Thanks

    Sounds like you have a momentary switch. Buckpucks need a maintained switch.

    These are nice and reliable, and they handle lots of amps easily.



    they also can be used with an external handle bar mount like this.

    Nice but what are they? Where do you get them ?
    Do you have a link to provide, please?
    When you think that life is though, keep a positive attitude : remember that it is short ;-)

    Hi Calina, I hope Uzzi does not mind if I answer the question, but the pic is linked over to e134's site (who sells them for $5 which seems really reasonable).

    You could just use a 4.7k or 5K ohm potentiometer (linear, not audio pot) and forget the switch, or use a on-off-on toggle switch and wire resistors to get a high and low value (this is the most practical approach) - there have been some really good write ups of that setup. If you want to get really fancy, you can even control it with PWM using a PIC micro controller. The Buckpuck datasheet has some examples and a graph that shows the relationship between the output current of the driver and the control voltage.
