does anyone know at 2A, how many lumens does the OSRAM CSLNM1.TG LED make?

Have you tried taking a look at literally the first post in this topic?

Has this stuff been tint and CRI tested? I understand these are no high CRI emitters, but the information still matters. 


 


BLF X5 (White Flat 1mm2 from LED4Power)

Hot spot:

CCT = 8823K (Duv -0.0110)
Color Rendering Index (Ra) = 69.6 [ R9 = 2.6 ]

Spill just outside hot spot:

CCT = 6701K (Duv -0.0048)
Color Rendering Index (Ra) = 67.5 [ R9 = -19.0 ]

Wow that is pretty bluish, doesn't it? Sort of like 9300K temp adjusted monitors.

I have put the 1mm2 on the TX25C2 MTN Electronics 22mm FET driver, and the hotspot is the same size as the Thrunite TN31 but not as bright, it throws a lot. I don’t go over 75% power, when I do it turns pinkish to let me know that it is not liking the current.

The other 1mm2 was put on a Manker U11, made it more throwy, the last one will be put on the Manker T02

I re-measured the hotspot further back just to see, didn’t make much difference. On turbo it’s more purple than blue, probably since it’s below BBL

Note this is turbo and between 4-5 amps IIRC:

CCT = 8932K (Duv -0.0116)
Color Rendering Index (Ra) = 68.8 [ R9 = 3.6 ]

Hotspot on a much lower setting:

CCT = 6873K (Duv -0.0030)
Color Rendering Index (Ra) = 66.2 [ R9 = -25.2 ]

Which driver did you use? Purple tint suggests current is higher than 4-5A.

So white flats' CCT steers to higher numbers when overdriven? I see R9 gets better but let's say I'd prefer to minimize tint shift. What would be the maximum reasonable driving current for the CSLPM1.TG (2mm²), 8A maybe? Host will be a C8S.

It’s an x5 (fet) using vapcell 14500. Don’t think it’s above 5A. It’s not very noticeably purple just trying to convey to barkuti even though cct is high it isn’t angry blue like a $3 zoomie.

I measured a zoomie that has like 12-14 7135 and the tint is similar on max. It’s not overdriven by BLF standards

194kcd with CSLPM1.TG in a C8 driven at 7.5A with LD-4A driver.

Interesting result. Almost the same as my C8 with black flat in that made 196kcd but with noticeable bigger hotspot.

CSLPM1.TG / Black flat

!https://i.imgur.com/1Ai1Xae.jpg!


I’ve been looking through this entire thread, is this the only direct comparison between the 1mm^2 CSLNM1.TG (or Flat Black which is comparable size wise) & the 2mm^2 CSLPM1.TG? So both will produce a pure circle hotspot, the PM1 will just have a slightly bigger hotspot. Will the PM1 spill also be circular?

Then another question, how will a triple reflector like the BTU’s deal with the PM1’s rectangular shape? Is there an optimal orientation to place the LED’s?

Thanks

Is there any indication this will be offered in a temp closer to 5000k? This led and the SST-40 only being available in cold white/blue (to me) is why I don’t own any lights with them. I’d rather dedome an old xp-g2 or something than have a cold white light, but that’s just me. Doesn’t have to be crazy CRI-tint snob level, just not icepick blue please. Anyone with knowledge of the industry have a guess on if they’ll ever come out with a somewhat warmer option?

I don’t have any answer about a possible warmer tint, but I do know something : they are no blue by any means.
What you got with the white flats is a true cold white. It’s white, no hue of blue or green, just white.
Still, I agree with you, a warmer tint would be useful, especially in a long range thrower to cut through mist and fog.
