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

It all depends on eachother, the thickness of different Mcpcb’s will differ , which allows more or less space in the head and that will affect the allowable thickness of the spacer and your focus, thus throw.

Focusing my white flat C8 took me more than an hour, but i eventually got it right.
Reaching over 200kCd on a standard Biscotti driver :smiley:

This was taken before final focusing

Those are some excellent numbers, i hope that i will be able to hit that 200k number.

This C8 has slightly modified head and bezel, the reflector can sit and create enough pressure on the mcpcb without even needing of any type of gasket, before the mods the reflector outer lip was resting on the flashlight head and the reflector was not able to go all the way down, now without that problem i can play with the height of the reflector as much as i want, not looking forward to all that tho :confounded:

Yup, not sure what the lens was originally used for. Guessing a big rear projection TV? With a Olsen Flat black at 600 LM it did 2.6 MIll. LUX measured at 9 meters. And heres the kicker,2.6 mill with out the magical collar.

Meanwhile my collar will continue collecting dust until a new flashlight comes out

So you have some new friend called Olsen Flat who is black?

Anyone tested Osram “red flat” and “green flat” leds?
What would be the max current they could be driven at?

Size comparison: CSLNM1.TG vs CULNM1.TG vs CSLPM1.TG

I tested the green flat but not the red one

The CULNM1 should have a lot of potential, since it has the size advantage of the boost HX but the smaller die advantage of the CSLNM1 which means less heat and more overdriving.
I can’t wait to test mine when I receive them :slight_smile:

I wish I could buy them on a 32mm MCPCB for even better heat transfer, but noctigon doesn’t make one that fits this size, only XP size.

Apart from the performance advantage, because of its size it is easier to center in flashlight builds, in a XP-L Hi host (there is many of them around) usually a slight reaming of the stock centerpiece does the job.

It is a pricy led though…

The half-hour of reaming I did and the calluses that lasted three days would like a word with you.

:frowning: I’m sorry about that. I have one of these reamers, and I grip the centerpiece with a small bit of bicycle inner tyre.

But you did get it done I hope?

That's the part I'm missing.

Yeah, it's in my Z1 and doing amazing things for its size.

Correct me if I’m wrong but it seems like this new CULNM1.TG has a slightly higher vf and can handle more current so it should be able to run in direct drive with a 10 amp cell.

It is not easy to predict that, but you may be correct if no springs are bypassed. But try it and report! :slight_smile:

So i received 4 pieces of this leds 2 days ago from intl-outdoore, unfortunately 1 of them is not working (haven’t contacted the seller yet), so i decided to replace leds on 3pot lamp. it was a really difficult job to fit 3x16mm boards, because of very low clearance between reflector and solder point on mcpcb, for now i have insulated it with electrical tape. i didn’t sand down centering gasket as of now. here are some pictures -

when both lamps + headlight is on

when headlight + 1 lamp with xml2 leds are on

when headlight + 1 lamp with CSLNM1.TG leds are on

unfortunately i can’t turn off headlight because no switch for that.

from sides-


lamps -

so far i’m happy with it, but i was kinda expecting more throw.

Maybe these two are related. The White Flat demand very precise centering and focusung to obtain a decent hotspot with maximum throw. I can not judge that from your pics, maybe it is optimal already, but the focusing could be something to look into.

Very nice slopegatri70 !

But Djozz already mentioned the focusing, i have the same experience with the CSLNM1.TG in a C8. Centering is very difficult without the right gaskets, but it really makes the difference.
Not to mention getting the right focus, which means gently sanding down several gaskets until the correct height until you find the sweet spot :wink:

i figured it will require sanding down gasket, but there won’t be enough clearance left for soldering those 3 boards in series, if there was a way to reflow these on original 3x xml-2 mcpcb it would have allowed me to sand down gaskets. but i couldn’t find similar mcpcb.

btw, CSLNM1.TG can be used on xpl board, right ? because the 4pot lamp i have uses xpl leds and not xml-2 leds as i originally thought. so maybe i should order some bare CSLNM1.TG and reflow ?

does 3 vs 4 pot reflector dictates throw angle ?
