Convoy C8+ and CULPM1.TG like Funtastic wrote.

Get zero warranty from Convoy and get him to build my custom version for hunting.

- C8+
- Osram CULPM1
- Ramping driver
- Use a Samsung 30Q for 8-9A

Convoy models usually come with a rubbish spring bypass, so you should redo it yourself. I always install dual springs on the tail.

This build gets 1,300 lumens with a range of 977m

The ramping driver allows you to set your own brightness on the first two settings, so even though it gets hot quick at 100% you can lower it to what suits. Convoy just can’t give a warranty on the LED since the driver has no thermal Regulation. 100% gets approx 2min 20sec before reaching 50°C at a room temp of 23°C.

….or grab the CSLNM1 LED at 5A for 700 lumens at 962m. The NM1 LED just has a narrower beam, so it depends what your preference is

If you can handle the NM1 Green, at 5A it gets 1,150m with 1000 lumens.

Here’s a demo I made for my website featuring the same models above

The Convoy S2+ with CSLNM1 gets 387m. I also have a demo for this below

Just keep in mind that any Convoy model the uses the Osram LEDs will have rings around the hotspot on a wall. These are overlapping ovals around the hotspot, not noticeable in use though.

This is common for the PM1 Osrams. They use a rectangular die and unless they are absolutely perfectly centered they seem to create an unbalanced corona. With a bunch of patience and attempts at loosening the bezel, spinning the reflector and or centering ring, and re-tightening, you may get it to and where you want it.

Another, thing to consider is the screws holding down the mcpcb. Simon (and everyone else I’ve seen) use flat head screws which cause the mcpcb to tighten into a predetermined position, which is often not dead center. Using pan head screws allows you to position it with enough freedom to hit center.

My process that usually works is to loosen the screws, run the light to thin out the thermal paste, tighten the bezel, let the light cool in the refrigerator to thicken the paste, and then quickly but carefully remove the bezel/ reflector and tighten the screws a little bit at a time to keep everything even and in place.

@JaredM
Thanks for reply. I think it’s not worth fixing for me at the moment, I can do more harm than good. Maybe I will try in future. If I touch led by fingers should I clean it or it wont affect the light from flashlight?

The LED can be touched but there’s no reason to. The reflector should be treated extremely carefully though. If you get dust or fingerprints on the mirror coated surface there is no way to fix that. Any attempt to clean a reflector nearly guarantees it’s further damaged. Dry compressed air (co2) is about the only safe method. When removing a bezel/reflector always do it with the lens facing down and let the reflector stay protected and contained by the lens.

I would recommend leaving it alone. Its actually not that bad.

Got flashlight today. Hope Simon will change his boxes in future because after trip from China to Poland my box was crushed, he could even sent it only in bubble envelope with same result. Unlucky flashlight came with chipping on body.

Should the spot looks like that? I mean “more light down”. I know it’s thrower but want be sure if it’s not something wrong with flashlight what I can correct myself without high skills.


That spot looks good to me!

It’s not bad especially when it’s used like it should be-for long distances but I wasn’t sure if it’s not any issue. Now I found that even Noctigon is having “problems” with Beam on osram LED.
In real life it’s not looking exactly like on photo but still not bad.

well thats exactly it, after looking at your picture i took three pictures. They are of my Noctigon K1 with CULPM1, my KR1 with CSLPM1, and my M21a with CSLPM1. They all have the effect yours have, and the pictures are favoring them, because as i move further away from the wall the corona distortion gets more obvious. . and they all throw AMAZING in real world applications. I understand there has been some slight (and i believe unnecessary) "negativity" toward Simon and his centering of Osram LED's but i think its a little blown out of proportion too. when, like JaredM said, with the -PM1 rectangular die, it is VERY difficult to get a perfectly centered LED, and for what? to shine it at the wall? nah, leave it alone. like you said, outdoors it is fine, thats what these leds are used for. theyre not night stand lights. On the other hand, ive seen some pictures of really bad centering, but those are very few and far between. Anyone who has ever modded a light knows how difficult perfection is with some of these things. 

 

In order from top to bottom - K1, M21a, KR1

@Artiet59
Thanks for photos. As everone said, it’s not for shining on the wall, it’s for throwingfar away where corona doesn’t exist.

@Tangra
Thanks for suggestion but I made decision 3 weeks ago Smile

I just bought this one for $26 or so and it seems to be the best Thrower for the cheapest price with a 7 amp driver and osram LED. https://www.aliexpress.com/item/4001110218988.html
