Can someone please confirm if 7.3A using the CSLPM1.TG 2mm version is safe?

These are lights I’m selling so they need to be reliable

7,3A for the 2mm is perfect,

Quote from the first post:

I also had opportunity to play with this larger 2mm white flat maybe even sooner than Led4Power. So this is mine pre- test with classic light meter and clamp meter (so test is just for reference before someone with better equipment test it). Full Samsung INR 30 Q. Single cell 18650 light with FET Djozz driver.

4.2V, 13.4A, 930 FC

4.0V, 12.5A, 950 FC

3.9V, 11.4A,1050 FC

3.8V, 10A, 1250 FC

3.7V, 9.20A, 1200 FC

3.6V, 8.20A, 1150 FC

3.4V, 7A , 1100 FC

Somewhere at 8-9A will be just enough…


A max at 10A is not what I found in my test (graph also in the first post), but rather at 7.5A. So you are driving the led at its maximum output, provided that the heat path in your build is good, or else you are already over the top. My advice, for flashlights to be sold, is to aim for 6A instead, you are at over 90% of max there and the led is stressed a bit less.

Hello, with Convoy l21a original driver at 6A the heat will be the same as the sst40? Or the osram 2mm produce more heat than sst40 at the same amps? I saw your charts and there is a Vf difference and of course the emitter area. Thanks

You will not see much heat difference betwern the leds if they are driven by the same driver at 6A. The power/heat at the led will be somewhat different but with the driver being lineair, the overal power/heat by led+driver combined will still be the same.

my concerns are about the temperature control using the 2mm and how it will be affected. the idea is to keep the ntc for extended periods on turbo/high without risk of malfunction, but at the same time, prevent a shut down by the ntc. Reliable flashlights for sale to regular / inexperienced customers, with better throw.

I removed the NTC and did stack the sense resistor to crank up the current to about 7,3 A
It gets nice and warm after about 5 minutes, but i havent used it for very long extended/continuous times, so cant say something about that.

I would avoid buying from Kaidomain for the moment until I get a successful reflow myself for testing. The 2mm has a slight purple tint even at 4.5A. djozz is thinking it may have been a bad reflow. It could be an entire batch as all 6pcs have the same issue.

My 30pcs 1mm do the same thing at 4.3A so I’m selling at 3.5A (650 lumens) with stacked 7135 chips

Next purchase will be from led4power

I always remove the ntc since I had it step down at 35 degrees instead of 55.

You’d get roughly 8 minutes on Turbo before 7.3A hits 55 degrees at that point it drops to quite a low output.

Convoy’s drivers aren’t configured the best for this led.

I might use led4power’s drivers but they are expensive

So do you think whoever is doing white flat reflows at Kaidomain is doing a botchy work? @#$%, I have a couple lying around.

Will mount them on an old PC heatsink, set a small narrow beam TIR lens on top of the emitters, and proceed with some testing with my power supply and smartphone as ceilingbounce luxmeter.

I’ll see if I can capture it in a couple photos

I’m not 100% since this is the first time using white flats. I did attempt a reflow, a terrible one, and it was instant purple. It was the same tint but much worse, which feels like that confirmed it for me. It would have been a different story if it was blue but it was exactly the same tint

Ordered some lead solder paste to try again once it arrives.

Can someone tell me where to get centering rings for the Convoy C8+ using the 4040 1mm white flat?

Seems like this is much better than the 3030 version

To my knowledge, nobody is making them for 4040. You can ream a 3535 out to fit, which is what I’ve done in my lights

Did you get the 5400K version of the 2mm WF from kaidomain? This LED has a noticeable purple tint to it compared to the typical pure white WF.

Yes, I did. Is this normal?

Maybe I should get djozz to test one to confirm it’s not an issue.

I believe it is normal. It is quite purple-ish, but the output is close to other pure white WFs I got from mouser. IMO the tint worked pretty good outdoors.

I appreciate your input, thank you

At 6.5A I was getting 1200 lumens and 7.3A 1170. Looks like around 7A is the limit for KD 2mm

measured 4.5A at the tail

That is very similar to the smaller LEP light with 250K.

If I pay someone to mod a Jaxman Z1 – will I get similar results ?

It would be cool to have a Turbo[4 min runtime ] and a near turbo ( 15 minute run time] Medium high and Low and moon mode

Yes you will, last week i hit the red white reflective sign at the end of the street which was 1,27 km
That was with a LED4Power FW 1mm2 3030 in a L21A with a 5 Amp driver.
Where are you located?

But fewer legal issues to use an LED , especially if less than 10 miles from an airport .
Not legal to even use any type of laser outside even with no planes in sight.

An LEP is not a laser and can safely be used by planes.

AFAIK all current handheld LEPs are rated as class 3R or 3B lasers depending on the specific model. Whether that refers only to the laser diode inside, or the whole device is NOT a question many would want to have to sort out in their own criminal trial.

Vehicle mounted LEP arrays wouldn’t have or need anywhere near the same level of collimation either which is certainly a consideration in eye hazard for lights/lasers. This is the only thing I could find in regards to LEPs and aviation use: https://www.faa.gov/pilots/safety/pilotsafetybrochures/media/LaserEyePro...
LEP stands for Laser Eye Protection in this case, pretty much the opposite of using the LEPs we usually mean as aviation lights.

LEPs are laser excited phosphors.
Instead of a blue LED there is a blue laser diode.
The light produced by the phosphor is regular white light like any LED, it is not laser light.
Also collimated flasshlights don’t case eye damge like a laser can.
Even though it is near collimated, the cross sectional area is hundreds of times larger than a laser and won’t cause eye damage.

I mean you’re completely right, the question is whether the law will consider something that uses a mirrored laser to create light from a phosphor (and then has multiple lenses to focus that light) anything except a laser itself. Especially with the beam it produces, and whether or not someone could blind pilots with it… it certainly will look like you could to most people. I think the smart thing to do either way would be to not use it near an airport if your areas has laws against lasers in a certain proximity. I’m not even sure the laws everywhere will distinguish between an actual LASER and any light emitting device… just in case someone thought it would be funny to point their 1940s searchlight at a 737 lol.

Do we have close-range intensity numbers to support that? They are hundreds of times brighter than a 5 or 10mW laser.

Look up NOHD, that’s the distance where you can get (termporarily) blinded because your blink reflex isn’t fast enough.
For example a 2W laser with 272Mcd (from wickedlasers) is at like 126m.
Since the beam of a laser is so thin and has such a small divergence, it’s safe to assume the whole beam can enter your pupil, which is 17000cd at 126m.
Not only is a flashlight like a maxabeam (with 12Mcd) far less powerful in the first place, it also has a beam diameter of 5.5” at the head, with 1 degree of divergence, which at 126m would be over 2m diameter.
This is over 3 million square millimeters of cross sectional area.
If your pupil has an area of 3mm^2 then that means that only 1 millionth of the beam intensity is actually entering your eye.
At 126m the maxabeam is 756 candela, so only 0.000756cd is entering your eye.
So that’s like 20 million times less intense than the laser.

.
If you had a giant magnifying glass and you focused the whole beam from a flashlight into your pupil, then yeah you can get eye damage.
But since the beams of flashlights (even the best ones like a maxabeam) have very large divergence, it’s impossible to cause ocular damage, not enough light can eneter the eye.
Also the maxabeam is far more powerful than any LEP that exists, and has less beam divergence, so it’s a pretty extreme example for comparison.

You’re confusing lux (illumination per unit of area) with candela (peak intensity) Candela can be a single point within the total beam and the surface area that you’re covering with beam of “X” intensity doesn’t matter. If 17,000cd at 126m is rated an eye hazard, then 17,000 (or the significantly higher numbers from LEPs and other lights) at point blank is a hazard too.

If you could theoretically block out 90% of the beam (from a cross-section perspective like you said) of an LEP the cd would be exactly the same (assuming consistent intensity throughout the whole beam, which probably isn’t true to be fair).

Just a correction to my measurement of the C8+ using the Osram W1. I forgot I was using the wrong centering gasket as the 3030’s hadn’t arrived at the time, range increased from 850m to 975m

I have question for you folks: do these Osram leds work “better” (meaning: to generate more throw) on larger or narrower reflectors?

I saw this flashlight that has a long and relatively “narrow” reflector :
https://www.aliexpress.com/item/4000751639079.html

I was wondering if it might have a good effect or not (let’s say with an Osram 2mm2).

Thanks in advance for your input Thumbs Up
