    Simple 'Achesalot' housing

    Patiently waiting for 3x XM-L T6 's from Santa. Meanwhile, I cobbled-up this ridiculously easy 'Achesalot' style housing, using nothing fancier than a 7/8" holesaw and a drill-press! In fact it's so simple I feel a bit embarassed showing it on this forum.

    This light is intended for the bars, so I used a 200mm length of thin-walled 25.4mm square-tubing, which is very lightweight, while offering ample surface-area for cooling. The idea is I can easily trim it smaller, once the dust settles. Here's the front panel, showing 3x 22mm holes, behind which a thin sheet of lexan (or CD-cover) will get laminated.


    Here's a mock-up of the heatsink. The idea is to bond 3x XM-L's (on 20mm stars) onto this bar using arctic alumina. The bar fits snugly against the back panel, and will bond to the back panel via thermal grease and metric-bolts.


    Finally, here's some readymade plastic endcaps, from my aluminium merchant. They're a perfect fit in the tube, but I'll probably silicone them in just to be safe...


    Now all I need is some goodies!

    Hey Chris...

    Hee hee, I'm kinda making it up as I go along, 'cos I find it's more fun that way.
    However I have 3x Reginas in the mail, which I'm expecting may require minor mods to fit inside the housing. However if you reckon Laura (or some other optic) looks good then I'll probably give that a bash too.

    Driver-wise, I have access to a badass regulated power-supply that should be ideal for bench-testing. But beyond that, I'm still tossing-up between HipCC or perhaps even a homebrew driver built around the LT3604 chip.

    Summing up, I have absolutely NFI, so suggestions welcome!

    I suspect you'd have good surface area with 200 metres of tubing hanging off the bars ;-)

    Can't help but look when I see my name mentioned :-)
    Aside from the square aluminum tubing, it looks quite different from my builds. Good luck to you and enjoy the DIY bikelighting experience!

    Sorry mate!

    Hey Znomit, very sorry about wrong attribution, hee, hee! Yep, I knew this rectangular-tubing design looked familiar, just couldn't recall who pioneered it first.

    Ah well, good news is my XM-Ls and optics just arrived.

    I got some xml's and regina's today too. Did you get in on the group buy at cpf or is it just a coincidence that we got 'em the same day?

    Wasn't really aware of the CPF deal, plus I'm in Oz so I simply ordered bits from Cutter.
    So I think the timing is probably just coincidental.

    Pics

    The 'znomit' light got shelved for bit, due to flooding, and other events. Seems to have shrunk a bit, but anyhow here she is...

    You Aussies are tough! My condolences go out to you and your mates in regard to the flooding. Yank that I am, I was there (Toowoomba, Brisbane, Noosa, etc.) back in 1990 on holiday, got to see historical evidence of previous flooding from decades past in those areas at a rest stop along one of the highways (waterline marked in permanent ink). Keep up the lumens and keep your eyes peeled for those crocs!!!

    Beamshots

    The dual XM-L + Regina headlight has been lighting up my commute most evening for several weeks now, and I'm more than happy with its performance. It certainly puts my old MC-E light to shame. Here's some pics...




    Dunno what to make of these beamshots, except there's not a lot of throw.
    Exposure 4 seconds @f4 ISO 80


    FWIW, I measured 18m to that big tree, and ~60m to the distant trees.
    Also, my perception is that scene appeared a bit brighter in real life than the pics.
