    7 up XML, tell me what you want

    I mocked up U2 2B XML on our 10mm MCPCB and put under new 7 up Anna, very nice, so I can make a 40mm 7 up for these, but should I, give me some feedback
    Cheers

    I guess the concern becomes the amount of heat such a board could generate at full burn. I'm almost thinking under driving would be the way to go... lots of light with high efficiency. Might be a nice upgrade for my Toutie 7up lights. Would the Polymer 7up optics work?

    I'd be up for at least one but only if populated with neutral white emitters.

    Yes that will be the concern however I have ordered some Copper backed PCB for 16 x XML 10k lumen monster, we trialled it on a Pentium heatsink and works well. Will be more expensive PCB but will be more thermal warm and cuddly

    Heat from a 7up will be pretty extreme. I'd rather have a 3up copper MCPCB, much more manageable and should be able to get just as much light out (no way you cam drive a 7up at 3A).

    Any chance of a thicker-than-dx copper 1up MCPCB XM-L? Would love some in neutral white.

    We can look at the copper star. The idea behind the 7 up would not be to run at 3A, its more about having the most efficient emitter running at the most effective output

    Yep, understood, for biking I'd rather have the smaller light head of a higher amp 3up, or even two 3ups running efficient currents than one 40mm 7up. Wide and flat easier to deal with for me than big and round.

    That said, I bet the flashlight guys would love it!

    Have you ever considered a 6 or 7up in a bar shape? All in one row...that'd make for some very easy housings.
    I WANT TO BUY YOUR MAGICSHINE LIGHTS! Working or not.

    Linear in a 2/3/4 option spaced to suit CXP optics(I guess regina too) with +/- clear of the optics holder. You could stack a 3 between two 2s for a 7up.
    DIY LED Bike Lights:
    A few Dynamo builds and some Small battery lights

    Liking Znomits suggestion alot

    all 3 sizes are drivable to the max if needed and ledil are bound to make some xml friendly optics in the trusty square format

    What's the battery and driver solution for a 7up?
    Getting my bike lighter will be void with a monster battery strapped to it..

    Are the 10mm MCPCB's for the xml for sale? I did not see them on your site, but would be interested in getting a few to play with. Seems a better option for modders who want to user smaller optics.

    Yes in the leds on MCPCB section

    To be honest I dont see Ledil releasing XML Optics in 20 Square, if they do I would expect them to wider angles. off course I am saying this hoping they will immediately prove me wrong by releasing some

    Hmmm... that's a good question. I'm a big fan of Taskled drivers due to excellent design along with the great support provided by George.

    You could drive a 7up XML with a MaxFlex but then you'd be limited to under driving with 1330-1400ma. Not necessarily a bad thing as this would keep the heat manageable and the lower current would provide very good efficiency. Ideal battery would be 14.8v 4S lipo.

    For max current I was going to say H6Flex, but realized it wouldn't be appropriate because it can only drive a maximum 20 volts which unfortunately isn't enough for 7 XMLs in series.

    Maybe H6CC since it can push 24 volts but it is a fixed current device (set via trimpot) so not ideal... at least not for biking purposes.

    Anyone have other ideas?

    size and space
    first thanks for the feedback.
    the 7up, 40mm be cute, but not flexible in terms of space.
    most available, 20mm star, and 20mm optics,
    as such, a 40mm is to small / specialized for my taste.
    no smaller than 50mm, probably 60mm+ be good.

    best, a 4-6up with 20-25mm spacing,
    as to mix single optics.
    otherwise, it be all or nothing, in terms of optics.

    Also waiting for the MTG to be available on a 20mm star , since that one ,
    can take more power, and has improved temp junction.
    Other thoughts, to have some flexibility with the wires.
    to run 7 x , you get to use boost drivers only.
    with a 2x 3x 6up, in 2 section, you could use 2x cheaper down drivers.
    I mean 7x leds, get expensive, + driver ,...
    lots of folks are exited, but when it boils down to cough up 500 bucks + sans battery and charger , you don't see to many bids.
    on that note, it might just be a nice option, to have the Xup
    to offer the same , in a 5up or 3up, I like in 2+, 2x 4up , 6up,
    cheaper, but also the drivers are a challenge.
    what do you think?

    I have my order in for some 3x XML 32mm boards and cute optics, but would like to go smaller. Has anyone tried the XML with the carclo 20mm triple optics? I'd really like to see some 20mm triple XML boards, but unless there are decent optics, whats the point.

    Heck, I'd like to see decent 20mm triple optics for XPG let alone XML.

    I thought they were going to have boards with LEDs mounted on them available. But all I see is boards. Am I incorrect?

    what do you think?
    20mm MTG MCPCB will be here by weekend
    How about the 7up in 3 series strings to allow more voltage driver flexibility, colour mixing possibility ie have some neutral or warm with cold to mix white?
    The real issue as always is the tail wags the dog, the nice optics are what make the led effective

    Were you also thinking about direct thermal path between led and MCPCB? This would solve some serious heat issues when driving leds @+1.5A.

    Not sure about the cost ramifications, but since were throwing this to the floor why not

    don't think this is possible with xml !?
    since any solder, would make it sit not flat,
    and also be a possible short hazard.
    only seen it with mce's , what was nice.
    for my guess, the XML at 1.5A is more than happy on a metal core board.
    once you get into the 3A,.... your housing is most likely the bottleneck.
    Anybody knows, where to order metal core pcbs, + LED assembly ,
    for proto's ,small order? thanks.
