    Default Fenix L0D Aspheric possible?

    I don't recall seeing it, and not finding anything on searches, so wanted to ask.. Would it be possible to 'mount' an aspheric lens on a L0D, without modification?

    Only problem is know the lens has to be a perfect distance from the emitter so it might not be possible, but perhaps. Ideally I could put it on when I want it.

    The L0D is a great little floody light compared to my others, and with the 10440 it puts out a really nice wall of light, just be nice to focus that into a nice spot on demand.

    EDIT: List of potential sources of aspheric lens:

    • Dorcy 1 AAA(45 lumen version), gen 4 Review

    • LEDLenser (link, anyone? I keep finding 3AAA which seems too big)

    With the right sized optic, I don't see why not.

    The Dorcy 1 AAA(45 lumen version) has an optic(review) and I do recall someone installing a hemispherical lens in a modded Ultrafire(?) AAA light.

    well, its generally recognized that aspheric lens are not a good combination to use with lights using reflectors.

    Yes, I forgot about that. Reflector aspheric combination usually gives you an ugly beam pattern.

    I would remove the reflector and either paint the insides white or have a white layer inside so some of the light is reflected and is redirected by the lens to form some kind of a spill.

    A lens that fits in the L0D's bezel will never throw exceptionally well. The die size is too large in relation to the lens for the light to collimate tightly.

    If you're going to paint the insides white, you might as well leave the reflector in.
    A little madness never hurt anybody.

    Classic case of "why can't one light do it all?"

    The LOD has a reflector of around 3/8". You just are not going to get a thrower out of that diameter of light. If you need an EDC that can throw, I suggest a CR123 sized light as these are about the minimum size for a good distance thrower. Good luck.................and keep the LOD!!!!

    Well, if you see my signature, I have many more that throw well enough but it would be fun to be able to 'convert' the L0D to a thrower sometimes.

    But I think it's not possible without modifying the entire light, which isn't what I want either.

    I took out the aspheric lens from a "gen4 spot Dorcy" tonight, and stuck it over the end of my mag Solitaire, (It fits if you put a piece of tape on the Solitaire's bezel). I used only the clear plastic lens, which separates from the white plastic that holds it in the Dorcy.
    Lo and behold, it throws better and the rest of the beam looks nicer, too. I should mention here that I have the ArcMania Super MJ LED in my Solitaire.

    Anyway, I'm thinking that the lens might also fit on the end of your Fenix for the times when you just gotta have a little more throw.

    "Do you have pics or dimensions for this lens?"

    You can find pics of the Dorcy AAA gen4 spot on this thread: http://www.candlepowerforums.com/vb/...d.php?t=190151

    It's the purple one. You unscrew the head and just push out the lens from the inside with an object that won't scratch it. The process is reversible if desired, so there's no harm in trying it.

    Sorry, Crenshaw--no luck. My Target didn't have any AAA Dorcy lights. Maybe someone else could try?

    Will it even fit? I know the soli is sifnificantly smaller in diameter than the 14mm L0D.

    The reflector in the l0d head isn't a problem is it? The front part of the head in front of the emitter can be unscrewed just like the rest of the head. You can have 2 of those and munt an aspheric lens in one of them. Then you can change between reflector and aspheric all day long, if you feel like it. I allready tried holding an aspheric lens in front of the l0d without the lens part, and it seemed to work fine.

    I just tried to hold the aspheric lens from a ledlenser in front of my lod, it projected a perfect image of the die, the size seems to fit, its made of glass too

    But to get the right focus you would need some kind of tube to hold the lens in place

    Thats alright, thanks for the gesture though...
    maybe ill post a wtb for one..

    this is starting to get interesting.Khaytsus could you maybe keep a running list at the top of lights with aspheric lenses that might fit the LOD?

    Sure, I'll go through the thread and start listing in the first post. I haven't gotten out this weekend to look for the Dorcy light myself or I'd be trying it

    That's an interesting concept. Could you (with enough interest) get a custom run of maybe 75 aspheric lenses that would fit, or is that not feasible?
    Need a website? PM me or go to http://www.maxphstudios.com -Mention you're from CPF, and we'll work something out

    The ledlenser is a crappy 4xAG13 powered round spot like beam.

    I think its called minimoon, but it will only focus the beam if I hold the lens a few millimeters from the LODs front, maybe we need a lens with a shorter focus...

    Its the 1 called V1 moon lenser halfway down the page.

    you could just cut a bit of plastic tubing or something, to space out the lens...is the diameter flush with the rest of the LOD?

    thinking of telephotos are we?
    finding a PVC tube that small may be a bit difficult, but if you can, cut it in half by length and fit the lens in in that manner before gluing it back in place.

    actually i was thinking of piping, as in, like hoses, you know....cos cutting it that small, it would be rigid enough to hold a circular shape...

    I used a 1" piece of pvc pipe to fit a 1" aspheric lens on my rexlight. its removable and focusable with 1 hand. to give it a tight fit i added some velcro tape to the inside of the pvc pipe (the fuzzy side of the velcro).

    it works like a charm, and i think an lod would be even better with the same aspheric, since it has a wider beam angle. the reflector on my rexlight truncates the beam before it hits the optic, where an lod reflector lets more of the direct beam hit the optic. light coming into the optic from the reflector is useless. the problem is you need a large optic to capture the whole beam.

    Hey whats the focus length of those
    Try holding one so that it projects a image of the light bulb in your living room onto some white paper ,,then you have the fl

    Hmm or a small one that has a short focus length
    If the angle of the beam is 70
    the lens only has to be 0,7xfl x2
    if the beam is 90
    the lens only has to be 1xfl x2
    If the angle of the beam is 120
    the lens only has to be 1,732xfl x2

    If a cree has a beam angle of 70
    and the lens has to be ( just a guess )12mm to fit
    the fl has to be 8,571mm ,,or shorter
    then you would capture all light coming out of the cree

    I dont think its possible beacause the focal length is closer then the lens of the jet-U.. i did try with a bare Cree, i did manage to get the projected image of the LED, but didnt measure if, shall try when i get home
