OSRAM CSLNM1.TG & CULNM1.TG 1mm², CSLPM1.TG & CULPM1.TG 2mm²

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

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

2] Bonus question- what about the twist zoom glass aspherics they use for cheap infrared lights T20 T38 etc?

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

Are those likely yield good results or too much work to mod for a Pro ?

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/LaserEyeProtection.pdf
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).

Anyone seen this? New 73mm zoomie?

No, looks impressive.

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 :+1:

Width, wideness is the biggest factor for good throw. The depth will keep the spill area narrower. I couldn't see any measurements on that light, but looks like about a C8 in width. I got a coupe lights with reflectors about the same dims, and no more, or much different than shallow reflectors. The old HD2010 was a good example of a wide reflector, shallow reflector but had good throw.

This led in a looong reflector will not likely do anything different than other leds: producing more or less the same throw as a shorter reflector of the same front surface area.

I’m a fan of those deep reflector lights though :slight_smile:

Took a nice bunch of lux measurements with my smartphone in front of the above white flats from Kaidomain (≈11 second averages with a luxmeter application, 0.1A current steps).

I finished quickly with the CSLNM1.TG (1mm²), I measured output at a few figures up to 5.1A (where I obtained its maximum) so I decided it was good to be driven at ≈4.7A with the Convoy ∅17mm SST-40 5A driver.

The 2mm² CSLPM1.TG was another story, noted down quite a bit of figures and while I could have gone a bit further (got a maximum at 7.4A, but given the previous and subsequent values I'd say that maximum was probably a tiny bit over the top already), I already had what I needed. No way 8 - 10 A, definitively. Between 6.0 and 6.7 A, I'd say.

Thanks TomE and djozz for the explanation about the reflector shape and its influence on the beam/throw! :+1:

Cheers for the info.

Did you notice any tint shift on the 2mm²?
