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

Thanks for the comprehensive data EasyB. Any reason you settled on 6A for the white flat? Curious what it could do in the EE X6 host with 8A.

Thanks,

From my measurment stock M2 has 75 kCd ( 3m lux reading distance )
With Osram 2mm^2 180 kCD ( 3m lux reading distance )

M2 Archer has step down driver set up to 6A to the led.
The stabilization is from 4.2 to 3.3V

You’re welcome. No particular reason for 6A except that it’s a moderately high current I might expect in a quad light with these emitters. Based on my output measurements the throw at 8A should be about 10% higher than at 6A.

Do you know if the Maxtoch M1 and M2 uses the same reflector? The length of the M1 is 10mm longer than the M2.

EasyB I added your test in a first post.

M1 and M2 has the same reflector.
M2 has side switch
M1 has tail switch and this is the reason of 10mm more

Thanks smokuxx1987! Good info, and even more impressive results given your previous readings. Good work.

Thanks for the testing EasyB. :+1:

Ahh, thanks for the clarification. Seems like the 2mm White Flat doesn’t perform too much better than the dedomed SST40. Maybe if the White Flat was driven to 8A, it might pull ahead more.

Nice testing EasyB! Even with the unavoidable uncertainties it gives the insight that these leds from different manufacturers are all close to each other.

Have someone found good centering ring for these and C8? Im using one from old Fenix right now, but it is for little bigger led and is little difficult to tune up although height is pretty good.
Btw org C8+ with XPL HI 6800lux and now 13200 with 2mm2. Own measurement method, maybe better to say I managed to gain 94%.

There is no from the shelf centering ring for Oslon leds, but if you can find one that fits your reflector and has a square cut-out for a XP-size led, you can make your own second cut-out for the Oslon led at 45 degrees from the XP cut-out using an exacto knife or scalpel, like I did for the mini-GT :

Wow! Nice work :o

djozz, what does the corona look like?

I will have a look again when I use the led in a new host (not in the mini-GT because it has a new led already), but I noticed nothing in the beam that pointed at the rectangular die shape, in this smooth reflector it produces a fine distinct hotspot with limited corona.

Corona in the X6 was round. I guess it makes sense since a reflector takes a circular average of the LED to make the beam. The same reason a square LED makes a round beam. I would expect a slightly distorted spill outline though.

Managed to get pretty good, although could be better.

I may be remembering wrongly. If so, feel free to help me out. :wink:

My understanding has been that a properly focused parabolic reflector takes aim from one central spot. All the light from that one spot forms the hot spot of the beam, and the rest of the light from the die is out of focus. So, the die shape shouldn’t affect the hot spot at all. If it is a particularly well focused reflector, the corona may show some rounded version of the die shape. But it depends also on how bright the spill is, and how it blends from corona to spill.

Not out of focus, but rather off-center.

A rectangular die (right) would make a slightly oblong shaped spot which is not really noticeable because of corona and also the fact that the CSLPM1.TG is fairly close to square.

Today I putted one 1mm2 white flat in a SMO reflector Convoy L6 with short tube and single 26650. You need to wait a day to measure. I’m at work and I only got a little time at home to done measuring while dark but before work.
