My Newest Flashlight - Wurkkos TS22 - Huh? Heat!

[Orion]

I saw a review on the Wurkkos TS22 and liked that it had an XHP70.2 in it, because of how large the die is and how it looks with the reflector. I ended up ordering one from Wurkkos, but noted that it had an XHP70.3 and was de-domed. I really wanted the domed version, but this is what I ended up with. First Huh? Second Huh? has to do with the amount of heat this generates. It is nearly unusable on high for more than 15 seconds. It ends up extremely hot. The hottest I've ever felt from my flashlights. So it got me wondering why. What is the point in having a lot of output if the light most likely would cook itself, and the switch, when it uses the amount of light?

If you wanna know what it looks like, it looks just like this one:

IIRC, the 70.3 is "HI," meaning high intensity, meaning without a dome. The 70.2 should be the standard emitter with a dome.

Maybe Wurkkos sent you the wrong emitter?

They stated it would be the 70.3 and really, it doesn't seem all that bright, even with the fully charged up 21700. But wow does it get hot quickly. If you let it run for more than 20 seconds on High, not even considering if on Turbo, even the switch would be very hot to turn off.

I probably should have just gotten the 70.2 now that I have it here. And shipping it back to them may be too costly, overseas. Not sure how that would work.

Seems like a mismatch of emitter to host. Such a large dome-less die would seem much brighter if it were in a larger head and reflector. The larger host would also be more effective with heat sinking.

Did you get a green or black host?

Unfortunately, that's most modern-day flashlights nowadays.
Highest setting is for a few seconds to quickly light up an area and scan it. Though admittedly becoming a very effective hand-warmer in only 15 seconds might be a record!

I got the green one.

It may in fact be too large of an emitter for the size of light. Maybe I should try to sell it, then get the domed 70.2 version.

I have the TS21 that looks similar but the tri flood.
I will say it too gets hot and honestly being new to these kind of lights and owning several Wurkkos lights i think they all get hot. But i rarely need them on the highest setting and when i do it's brief.

I know its apples to oranges for what it's worth.

FC13. I have a FCc13 that has the other emitter i guess i'll have to get out and check how hot it gets.

My latest fresh off the boat last week i'm guessing has the domed emitter does get hot on turbo. After a minute it stabilizes and i can still hold the end of it between my finger and thumb with no discomfort. It's rated at 3000lm.

the amount of heat this generates. It is nearly unusable on high for more than 15 seconds. It ends up extremely hot. The hottest I've ever felt from my flashlights.

Could it be that your other flashlights produce a Lower Lumen output, so they make less heat?

fwiw, according to this chart, from this review, the initial Turbo output of 3000 lumens, and initial High mode output of 1500 lumens, are NOT Thermally sustainable.. the light overheats on those outputs and the output steps down to sustain about 600 lumens..

If you want to use the light in a way that does not overheat, use Medium of about 400 lumens.. you can see from the blue line on the chart, that Medium does not have a Thermal Step down.

I found a review (https://forum.fonarevka.ru/showthread.php?t=51973), here in turbo mode it accelerates to 61 degrees Celsius in ~60 seconds and drops from 100% to ~25% brightness. This is a good hand warmer

The ratio of the reflector and diode is such that, in my opinion, the difference between led with dome and led without a dome will be minimal

I have four lights that I would qualify as high lumen lights. An Olight Seeker 3 Pro, Olight Seeker 4 Pro, Astrolux FT02S, and an Acebeam L35. The Wurkoss definitely does heat up much quicker and hotter. The last two on my list, however, do have large heads so it no doubt handles heat better.

As for this TS22, I still like it. The 70.3 is the "High CRI" and really does have a very nice tint beam. And yeah, if I'm running it less than the higher outputs, it does fine.

As a side note, I like this light enough to where I'm getting the 70.2 version as well, so I'll have a domed and undomed.

Olight Seeker 3 Pro, Olight Seeker 4 Pro, Astrolux FT02S, and an Acebeam L35

Olight Seeker 3 Pro weighs 7.06 oz,
Olight Seeker 4 Pro weights 7.3 oz.
Astrolux FT02S weighs 11.43 oz.
Acebeam L35 weighs 8.5 oz,
so maybe they handle heat better than the
TS22 that weighs 5.78 oz

Also Low CRI makes less heat than High CRI, and Cooler Color Temperature makes less heat than Warmer Color temperature...

> I like this light enough to where I'm getting the 70.2 version as well

glad youre enjoying your options ;-)

Definitely sounds like it's not dispersing the heat well enough. My Nitecore EA81 heats up in seconds radiating from the top of it. Gets a bit warm around the switch area too but it's to be expected from a 2150 lumen light. It's regulated too to avoid overheating.

An update. I did get the other TS22, with the 70.2 domed LED in and can definitely confirm that the 70.3 is a much better looking beam and color. Not that the 70.2 is bad, but I can see why the 70.3 is considered "high CRI". Having said that, the domed LED, in this light, is really neat looking since it takes up the entire reflector. All in all, I like the 70.3 better.

Any difference in terms of heat?

I really didn't notice much difference. But I don't have any sort of temp taking devices to check.

As a sidenote, when I got this other TS22, I also picked up a Wurkkos Titanium TS10V2 Ti-copper, because,....for fun....I guess. But on high, THIS light also gets really hot, fairly quickly.
