    Default DiveRite 10w HID to Aspheric XM-L

    Received this light this morning for an upgrade from a fellow CCR diver.

    The customer wanted a tightly focused beam suitable for murky conditions so we decided on using an aspheric lens to tightly focus the beam with no side spill that could cause excess back scatter.

    First step was to make up a heat sink.
    Second was to make up the lens holder.
    Third was to wire it all up.

    First pic shows the LED which is a Cree XM-L, 3 mode driver, aspheric lens
    heatsink and lens holder.





    This last pic is a beam shot of another light using the same components.

    Yah, very nice.

    I'd already rolled to a pill design for the led and circuit but your lense holder is just the missing piece!
    Is that black delrin?

    No air gap and flat lens forward of the aspheric? Sorry if it's there and I'm missing it. I'm viewing on a tiny phone screen.

    Those little DR lightheads work awesome for modding. I put the same driver and XML in one for a friend, but I use a Fraen MC-E reflector. Sweet setup.

    Where do you source your Delrin from..Locally or internet? Expensive?

    nice! Klem, I get 2.5" Delrin in the States for about $20 per foot. It goes up about $5 per foot every 1/4"... Pack, feel free to convert to metric... lol!

    I get it from a local plastics outfit. Sounds like Hector gets his somewhat cheaper.

    Nice work !

    May I ask. Friend of mine have Halcyon 10W HID which is made from delrin . He saw on DR pages LED dropin for DR 10W HID . ( some low power led )

    Is DR laphead made from delrin or aluminium ? How much heat produce XML dropin ? (Probably head shud be made from alu ?)

    Thanks.

    The head is aluminium & good to modify. I have done a couple of P7 - but am looking to upgrade with a XML.

    I am intrested guys - in the comparison of the atmospheric to a DX reflector - what are your thoughts?

    Which atmospheric did you use?

    It's Ok - just found the answer to one of my questions on the other thread - regarding the lense!

    Still intrested in your opinions regardind the atmospheric vs reflector - real life / under water.

    It looks like the way foward. It may have to be my next project

    it's an aspheric lens which means that it's surface(s) deviate from 'perfect' spheres. I'm making one myself but didn't finish it yet so can't tell how it compares underwater.

    Regarding aspheric vs. reflectors... I'm mixed about it. My current primary light is a ssr90 behind an aspheric. No spill of course. Absence of backscatter is great, but if there is no ambient light it's challenging. For example, I did a deep low vis wreck dive with nwbrewer in Sept. It was pitch black. The beam had very good throw but I couldn't even see my own hands. A little spill would be nice. On the other hand all my reflector lights have been too floody.

    Thanks - I blame spell checker

    Lucca - defocusing could be a good option to gain a little spill. Interested in the results

    defocussing will usually not help very much as it will just increase the angle of the cone of light, not providing a bright center spot with spill around it. You might be able to find something between the narrow spot and the floody beams that suits your needs.

    I'm working on a similar dive light based on a custom head with an xm-l. Where did you get the lens from?

    I thought that might be it. Now I just need to find one in the US. Shipping is really expensive for just one, so maybe he has someone in the US reselling for him.

    Buy 50 then! Thats what I did.
    Shipping per lens then becomes really cheap!

    I ship USPS in an envelope and can get a lens around the world for $3-5..

    Hi Packhorse,

    Thanks for sharing your lighting plans and executions, I'm finding them quite helpful.

    A couple of questions regarding this mod:

    1. Since this build have you found anything badder and brighter for the same design?
    2. What are the internal dimension you're working with in the Dive Rite head? And the length and diameter of your unit ready to drop in (heatsink, optic, delrin holder, etc)

    Just trying to get an idea if this mod is going to work for my light head. The dimensions I have to work with behind the factory lens are:
    63-64mm in length
    35mm diameter

    It looks to me from your photos that these measurements are likely quite similar to the Dive Rite head!?!?

    Thanks for your time in advance,
    Joel.

    Sorry Joel I dont know the length of the assembly. I think you should be able to squeeze it into 60mm though.
    Diameter is about 35mm ( maybe 34mm??)

    Badder and brighter? Triple XML from cutter consumers more power, has a lower lux, costs more ( thats the badder part) but produces up to 3 times the lumen ( there is the brighter part).
    Other combos offer other pros and cons.
    XML with a reflector will have a tighter spot but also add some spill light ( all depending on the reflector)

    Hey Packhorse,

    Thanks for your response.

    Yeah I was looking at the triple XML that Betti had done also. I'm thinking I might have a play with the single first though and see what the outcome is. From your shots it looks like it's a good amount of light.

    "XML with a reflector will have a tighter spot but also add some spill light ( all depending on the reflector)"

    I think I'll stick with the aspheric here. Diving here in Norway is (more often than not) dark, murky and rusty so I could do without too much spill.

    Cheers again.
    Joel.

    Hi
    If using the KD7 super output p7 driver pictured would I need to change my existing 9 cell nimh battery? The battery produces 13.2 volts at full charge.
    Can I get the same results using a DX Aspheric ?
    Thanks in advance

    Battery should be fine.
    No you will not get the same result with a different aspheric. You will get a different result. May be better may be worse.
