    Yet more triple Xpg questions!

    I have a couple of questions about another triple Xpg light. It will use a b2flex driver,3 Xpgs on stars with reginas and a 4S1P lipo battery. 2 questions:
    1) I haven't seen any comment on case shapes-Would there be a benefit to having 3 leds in a line versus in a triangle as far as light quality or am I spending too much time thinking?
    2) I would like to use a switch with a led indicator for low battery power. Any favorites?
    Thanks for the input!

    I can only give an opinion on Q1

    unless you do some careful aiming of the reginas it will make no seeable difference
    I have done 4 inline and 4 in a square and the beam has been very similar .

    on Q2, I like these a great deal. Not cheap, but I've used a few of them and they're nice to work with. Only trouble I had was with one where one of the stat LED legs broke off as I was moving the wire around too much, but I fixed that pretty easily. You can get them in different colours too

    btw, why not throw an XM-L with Laura-RS/ CXP RS optic in there? Reginas are v. nice, but they tend to throw a rather clearly defined hotspot and the beam has a sharp cut off at the edge (common to all reflectors). Adding an optic in there might help even the beam out a bit. Perhaps Troutie has an opinion on that, he knows his optics/reflectors better than I do.

    Troutie-Mtb- Thanks for the response. My builds are sloppy enough where I'm probably not going to accurately aim reflectors. I have some 1"x3" tubing and some 1 3/4 " square tubing, one of which will be the home of my next build. The square tube would be less clunky but heat may be more of an issue.
    Mattthemuppet- Thanks for the switch info. I have had extremely happy with my orders from Digikey-fast and positive. I think I will give your XM-L idea a go. I just ordered 2 leds along with the optics. This build will be of a sled design- where did that that idea come from? Thanks!

    Be careful about alignment of the reflector or optic to the LED. I have seen that there are noticeable losses in beam shape and brightness with less than .5mm position error
