Thrower for SAR

acebeam k75

I do fancy a KR1. I’ve got the C8 with SMO reflector and side by side with the L21A to my eyes the C8 doesn’t lack much. It’s a good bit smaller and lighter though.

To geht this clear, i don’t need the flashlight to search for people, thats what my dog is for.
I need it to watch, what my dog is doing. :wink:

In my experience a flashlight with an op reflector or at least a bright spill is quite counterproductive in an woodland environmand, what is common in Austria. You’ll get so many bright reflections from trees an leaves, that you won’t see very far.

Some of your suggestions are quite interesting, especially the one with built in USB-C charging. But the ones like the acebeam k75 are to large an heavy.

If size is a factor and you have to carry it in your backpack and hike, I would consider the Catapult V6.
It offers great throw, with a good sized spill. Its very compact and the 26650 single battery offers very good capacity.

Cheap C8 w1 is fine for you, better M21A w2. And you can try putting a tube on the head to dismiss spill

For that same reason you don’t want anything that is cold white. It lights up and reflects back everything between you and what you’re trying to see beyond those objects. Nothing over 5000k and lower if you can find it.

I already got an convoy s2, M1 and C8, but I do want something even mor throwing.

Thanks, I’ll keep that in mind.

For around $100, I like the Acebeam L18 or slightly more money L19. They have buck drivers for long, linear runtime with constant output, dual switches, and both throw over 800 m with minimal spill due to the optics. If you can swing the L19, I tested this light to throw 1300 meters and the L18 to throw 900 meters. It’s Acebeam so high quality lights with charging built into the batteries.

Acebeam L19

How about a Noctigon K1? Don”t know if its the right size for you. Throws very well with minimal spill.

If you don’t want blowback from too much spill reflecting off stuff right near you, go with a LEP. Pricier, but zero spill.

Or try a big zoomie like a Jaxman Z1. Don’t think Brynite still sells the venerable B158, but they do carry the Artemis (white/red/green in one, selectable on the fly).

I got a Cometa, a “cheaper” version (lesser-quality lens, for one) of the original Z1, and Mr Jax has an updated Z1 which is brighter, etc.

After thinking about it some more I suspect that most of what you’re interpreting as a spill problem already is a cold white problem that you’re dealing with. And many/most/all? of these new fancy schmancy throwing lights are cold white. Not good with a lot of trees and bushes around. You’ll notice that people pick their spots for beam shots that don’t look anything like where you have to see your dog.

C8 w1? It throws 850 meter easily

I have a K1 in the 90.2 and it’s prob my overall favorite light. But depending on how long you need to run it, it may not fit your needs. It is fairly compact and puts out a ton of light. I’ve got a ton of lights that don’t see more then 2 min of use on turbo. Mostly because I don’t need them that long, but also they are hotrods like the K1 on turbo will overheat if ran that long. Both the heatsinking and the battery reserve are really inadequate for any high output useage. If I am going to be using a light on high or turbo for extended amounts of time I’d grab a Thrunite TN40s. With this light I have no worries running it on the highest setting for any duration. The light is smaller than you might think. With 4 18650s I pulled this from their posting
Strobe(1100 lumens /9hrs),
Turbo(4450 lumens/85mins),
High(1780 lumens /2.7hrs),
Medium(580 lumens /9.5hrs),
Low(90 lumens /2.5days),
Firefly (1.2 lumens /57days).

Peak beam intensity: 331200cd.
Max beam distance: 1151m.

K1
SBT90.2 LED, 5700K, 4500lm, Lux: 420Kcd (420,000cd)

Consider how far away you can see, even with a light. Usually anything more than a few hundred meters is overkill.
I would be looking at a smaller, 21700 light with a 4000k emitter and reasonable throw.
Also, I think a reflective harness on the dog, together with an illuminated collar or fob would make it a great deal more effective.

Take a look at the Sofirn SP70. Lots of light. But a bit heavy.
Also the Streamlight Protac HL 5-X. The TIR front end give a different spot and spill.
I did a review here

All the Best,

Thanks for clarifying. I guess keeping track of your dog and actively using the light to search for people are quite different use cases.

In terms of reflection from trees and the like. I sort of get what you mean, but without being there to experience it, I guess it is difficult to really grasp how much of an issue this is and how much is beam profile vs tint etc.

A thin beam will allow you to shine ‘through’ the trees some what. But a more intense hot spot is likely to reflect back at you more intently too. I suspect a floody light does light up more in trees but where the light doesn’t reach will appear darker and the trees you are lighting up will cause shadows behind them. I wonder if this is more the issue?

As for which light……

The L21A is a great light with the W2 HX LED. And for the money it is good value for money. But they are only available in cool white. But it isn’t a horrid colour. In trees I’d assume your distance/line of sight is actually rather limited. So I’m still not sure how useful the beam would actually be. As closer up the beam is smaller.

A plus point for the L21A is the 21700 battery and heatsinking. These will give good long runtimes without ramping.

A major downside IMO is the balance and weight of the light. They are head heavy, so it won’t just ‘sit’ in your hand. You will actively have to point it and hold it up. I think for prolonged use this would get very tiring and weighty.

Maybe the M21 or a C8 with the same LED in would be nicer to hold and carry. And still offer the right type of beam?

I guess the FT03 SST-40 might work too. Not a dedicated thrower, but nicer to carry than the L21A. More of a traditional beam profile. Good spill, but fairly intense hotspot and moderately good throw.

The KR1 would also fit the budget, the most easy to carry and pocket friendly. But an 18650 will give lower runtimes (same with the C8). KR1 is smaller, so will heat up more if using Turbo.

Lastly and thinking out of the box a little. YLP Falcon F15:

Now this won’t be a throw monster. But the zoomy head will let you focus the beam for when you are in the trees. And the throw is pretty good for this size class. Should be easy and comfy to hold and carry too. And the lower output/amps mean runtimes on an 18650 will be better than the KR1/C8 with the Osram LEDs. I think there is a BLF code for these too.

I’m a dog handler as well. For me, I keep different lights with me or in my truck, I probably use my acebeam T27 the most.

You get my problem straight to the point :wink:
I think I’ll have to try different lights to see whats the best for me.

One thing i haven’t known was the problem with the reflection of cw light, thank you all for mention that.

It’s clear for me to use different lights in different situations. For close range I already have lights I’m happy with, but i have nothing for longe range.
The T27 has realy nice beamshots. Thanks for that.

CW definitely scatters more and causes harsher reflections. BUT, and this is coming from a hi-CRI obsessed person, sometimes it’s better at showing contrast. I find in the winter here in the snowy Appalachian woods, where you have three colors… Brown, white, and darkness. I’ve found that when everything is shades of brown, somehow the color fidelity issues with some CW LEDs actually help add contrast. I wish I could take good pictures to show what I mean, and YMMV. If I were to try to explain it another way… for me, the ‘greyscale’ is easier to pick out objects than with a ‘brownscale’.

Best advice I have is to try different lights. Check the FS adds and see what you can get cheap. Lightbringer mentioned a zoomie called a Jaxman Z1, that’s good advice for you IMO. If you’re so inclined, it’s a great easy host to start doing emitter swaps and figure out what works best for your environment, eyes, and taste. You can put a range of emitters in that host and have anything from a 300+kcd thrower to a high lumen even flood light.

Best advice in the thread though is a reflective harness/vest for your dog. An AA maglite could work at 150m in that case haha :wink:

Cheers!

I’d look at the Nitecore MH20GT but they don’t make them any more. It’s got that great combination of light weight and great throw (hence the GT on the end of the part number). The Nitecore replacement isn’t as good IMO. As an aside, I just bought some of these cheap things, less than $2 each US, for my dog -if I was lost in the woods in the dark it would make your dog visible to me.
