Noctigon KR1 Osram W1 change to what

Hi I have a KR1 here I don’t use because of the tiny hotspot it throws from the osram w1 emitter. I’m looking at carrying out a swap myself to something to that wil give it a large hotspot with still good throw, I don’t need to be using a scope to see what the hotspot is hitting, I’m hopeful for around 100m with a large hotspot.
I also have to take into account I’ll only be swapping the mcpcb so the existing drivers limitations are in force here with the current it can drive.
Sft25r is maybe a good option but how is the duv on the 5000k?
Then what about sft 40

Opinions and recommendations welcomed.

I think the SFT40 is a good choice. Also, the SBT90.2 would be amazing, but is really expensive and requires a lot of power. The SFT25 would work, but if you only need to see 100 meters, the SFT40 or SBT90.2 would have a more useful hotspot.

I think the SFT25 will be too similar to what you have. I’d go with SFT40 5000K.

Another vote for sft40 5000k. I have one in an 18350 S6 and it performs out of proportion to the small size. It should be even punchier in your kr1.

Osram W1 is very similar to SFT-25R in hot spot size, 25R is bigger but not by much, only noticeable when side by side. I would go with SFT-40.

Left is W1 right is 25R, both in a s2+ with smooth reflector.

Very helpful replies I will find an sft40 for this

W2 (CSLPM1.TG) would also be a good choice. Larger hotspot than the W1 (and a better light, as well). And it can use the same mcpcb you’ve already got in there since it’s also a 3030.

W1 left, W2 right. Both in S2+ with SMO reflector and 3v5a buck drivers.

Now that’s interesting, I’ll need to look into them too

My impression of SFT25 and W2 is that they are very similar, moreso than SFT25 and W1.

I mean… It’s possible with a different reflector, I guess.

Baton Turbo – S2+ – S21E

I have the SFT25R in several lights and they all seem about the same as what you see here.

Yes, what I mean is I think W2 and SFT25 are very similar, all else equal (if comparing two otherwise identical lights).

Thanks for the pic.
