    Idea! Spider Eyes

    A bit of experimenting for when the XP-G leds hit the shelves .
    If they run cooler and put out the projected lumens a tiny hi powered helmet light will be great.

    I got these 12 mm aspherics and have been having a play with them but wont know what they are like for a few hours untill it gets dark .

    Can't wait to see what the beam pattern will look like. With two XP-G's output should still be over 600lm. Even with XP-E's it should be interesting. I'm glad to see you are still experimenting with minimal (light weight) builds.

    There is nothing else to see yet untill I see what sort of beam it gives out .
    just on a bench power supply
    I suspect it will be a very narrow beam more suited to fitting on a gun than a bike helmet

    It is more a bit of experimenting and I might try one on a MCE later too .

    Here is the beam shot .




    bear in mind the trees in the back ground are 75 metres away and the ones right at the back are 150 metres
    so not bad for a little light

    but still impressive compared to leds this time last year.

    you'll be mounting them directly along the stem next with a switch within the grips

    Great experiment Troutie!

    sorry for my missunderstanding but are you using XP-G leds for the spider eyes? or which led?

    lovely narrow beam.....would be great to test it on an MC-E!!!

    Nice Troutie.

    Any chance of a beamshot up against a wall?

    And I just ordered a tight optic from cutter last night. Grrrr.

    @ that .

    I wish they were but sadly no just the XP-E R2

    Znomit .
    Will do but need to wait for tonight also want to compare it with 2 of the narrow tight optics.

    The aspherics are a bit of a faff to get the focus right I have these slightly defocused to get rid of the die shape a little.

    All things considered, I think you did one heck of a job.. Even with the XP-E's it is damn bright and with great throw! With XP-G's it should be even better. Most people probably don't like the narrow beam but I think it rules. One of these on the helmet and one ( or maybe a 3-up with more standard optics ) on the bars would be a really great set-up for endurance events...not to mention also for those of us who are real weight weenies.

    Ok here is the shot against a wall . well target with sizes on .
    Why dont the darn manufacturers do that then we would have a better idea of the beam.
    anyway the sizes are in mm and the outer is 1 metre diameter.
    distance from light to board is 2 metres.

    first up is the carclo 20 mm triple tight




    then the spider eye double.



    it can be focused even more to get a tighter beam but then it becomes a projection of the led die..


    and last now this is tight
    the Khatod 20 mm aspherical on an XPE



    I will add a shot with 2 of the Tight square optics later.

    Any chance we can see what the Khatod 20mm aspheric optic looks like? That is one tight beam!

    I think:

    The cutter links to Khatod datasheets are old and busted so here you go:

    Thought spiders had eight eyes.

    That is really cool. The XP-G sounds ideal for cycling applications I just hope we can get the heat out of the emitter with the small die size.

    I love that picture

    2 MCE with the Kathod aspherics and 2 of the 12 mm one with xpes for a jumping spider light.

    Be a good one for BBruno in Brazil.
