I finally threw a CULNM1 in my Jaxman Z1 (you know, with the nice glass lens). It's running off 13x AMC7135, so a nominal 4.94A. I might get up the nerve to reflow another one or two on there, but maybe not. I don't have a good idea for how well the Z1 handles the heat, and I roasted the CSLPM1 I had in it first. That was probably because I had something on the LED that burned up, but I'm not sure.
Anyway, it's my first aspheric, it's a glorious gosh darned pencil beam and it's just hilarious. I haven't been out at night with it yet (I finished the mod after 11pm Friday and had a busy weekend), and I'm sure my stock MF02 outthrows it, but it's my new favorite thrower. It's so damned small it will fit in a jacket pocket, especially when twisted down to flood mode. Jaxman sent a lens cover with it even, which I actually use. And just for fun, I ended up having to use a black, reamed-out 3535 centering ring for the 4040 footprint, so it projects a nice donut image of the centering ring around the square die image.
Even if not that important, yes. I carefully glued a 3535 gasket around the emitter, one which I had previously lapped to reduce its height from 0.8mm down to 0.6 or 0.5mm. The reflector sits quite close to the solder pads. I had to dismiss my first attempts, where I left the gasket at just 0.2 - 0.3mm and the reflector wouldn't seat properly due to it landing over the pad wires. O:)
I think that with a small reflector, it is indeed impressive. The beam is not straight all the time as it has a slight opening, but it makes possible to have a tube light (eventually in a 18350 version) as a “true” pocket thrower :partying_face:
Took some quick ceilingbounce measurements, got very close to 100Kcd for my M1. I don't know how accurate is my smartphone luxmeter. I have a Sofirn C01S in case anyone wants to help getting some comparative figures. Will measure again with the help of a friend in a day or two.
M1 speaking, adjusted my homemade setup and measured again: 101.5Kcd peak and ≈97Kcd at 30s.
I really don't know how the ceilingbounce application works 30s warning sound wise. I was hoping for the 30s alarm to reset upon pressing “reset” but it doesn't seems to.
I think this is about what is to be expected from such host, doesn't it? Its reflector seems to be about half of the surface of a C8.
Will this led provide any benefits on a reflector like these - in terms of throw @ 2 or 3 amps ? or i’m better off going with xpl-hi instead ? these are motorcycle auxiliary spot lights and i want to increase throw with making the beam more narrow.
above one is @3 amps
^ this one is @2 amps. asking this because i can’t increase the current. and it seems like white flat requires higher current. so before ordering new leds, just want to be sure.
well that’s a good news, i was reading a thread about black flat on Emisar D1s @ 5amp and manufacturer abandoned the plan so i thought maybe it requires higher current. one more thing, can i reflow it on xm-l2 board or not. and do i need to worry about anything else ? or its just replacing the led and go kinda thing.
i have never done dedoming before so that option is a no go for me. guess i will get white flat on 16mm dct instead of reflowing on current board. leds have minimum 17mm distance between them, so i think 3x 16mm boards will be fine. now only issue left is, these leds are 6000-6500k or above, but i guess you gotta lose something to gain something.
If you have enough center to center distance go for it slopegatri70, 3 × ∅16mm boards. Just pay attention at how is the stuff set up, very likely emitters in series (3S1P).
CSLNM1.TG (1mm²) is ≈6500K that's what there is. The tint is nice, though, my recently built M1 looks pretty white to my eyes, far better than most cheapass emitters inside cheapass flashlights. But ;-) cool.
Sounds like a plan that could work
Although there is some work involved, quite a bit of wiring, but the main problem to solve: you need a new way of centering those small 3030 leds: measure the reflector hole, find a source for 3030 centering pieces (intl-outdoor?) , maybe adapt the thickness of the centerpieces for best focus, and possibly ream the reflector holes to fit them.
Reflector hole is 7mm, and it seems like intl-outdoor sells 7mm gasket with white flat. yes those leds are connected in series. only thing i haven’t measured is space between reflector base and dct board, since i will need to solder some wires there to connect leds. i guess 22-20awg wire should be fine, will see.
hopefully experiment will be successful, i just want to narrow the beam and decrease the glare for inc traffic. previously i was modding BL70s with xhp35hi with aspheric lens, but beam intensity wasn’t enough so bought these lights instead.
I have also posted this in the L2/L6 modding thread, but this might be just the more appropriate place to ask
So i took the gamble and just ordered the L21a to build a nice thrower
Together with some high drain 21700 Shockli cells and the famous Led4Power 3030 MCPCB with OSRAM KW CSLNM1.TG and another OSRAM KW CSLPM1.TG
I am planning to keep the original driver, but still doubting which LED to use, @6A the 1mm might be just overdriven and the 2mm might be just underdriven.
