    Wiring Help

    I have a 6up xpg light I'm playing with and thought about tossing 2 xpg in favor of 2 xml. Trying to figure out a way to actually get a decent amount of current to the xml but I'm not seeing it. Currently, it's wired up in series/parallel with 3 strings of 2xpg and 3.6A current setting giving 1.2A each string. Can anyone see a wiring option to give maybe 2+ amps to the xml but still keep the xpg in a string of 2 and 1.4a or lower?

    Driver type and battery voltage would help to figure this out. An easy way but does not keep your 2S XPGs would be 2P strings of 1 XML in series with 2P XPGs. This would have a lower Vf than your current setup. If you are using an h6flex it would be fine.

    If you can set your driver to 2.8A the you could do 1 string of 2S XMLs in series with 2P strings of 2S XPGs. With a buck driver you would need at least a 14.8V battery.

    Driver is indeed a h6flex and it's going on a motorcycle so 12v battery when off and roughly 13.5-14v when on.

    I'm having trouble visualizing the first setup you mentioned.

    Here is an attempt to illustrate the two options I came up with.

    Kan thats what I just did with this build. I only did one half, single xml and double xpg and all looks good so far, although very early days yet as it hasn't hit the trails.

    That is going to be an incredible amount of light at full tilt, what optics are you using to focus the light?

    I'll be using regina for all of them. I wanted to get a little more spill off to the sides without changing the reflectors since the housing was designed around them. I think the 2 xml should give me what I'm looking for.

    I completely forgot you did that and now that I see the thread again I should have just referenced that.

    Ah, I didn't do a sketch that makes it a lot easier to visualise / understand.

    Are you going to put a hood on it or is this for off road use?

    Yes, electrically the same. Some say that parallel LEDs can have current balance problems. I have done a few parallel MCEs and never had a problem. Maybe just lucky, but I am not worried.

    Off road only with this design. It's good as it is but I just feel a little wider spill would help on some of the trails.

    I'm going to take your stance as well. If I'm wrong and I blow some up then lesson learned but they aren't that expensive.
