This is definitely an enthusiast flashlight and is not meant to be left on at high modes unattended. As an enthusiast, I prefer not having thermal protection than having very fast step downs that makes the turbo mode nearly useless, which is sadly the case with the majority of high lumen flashlights. However, a user programmable thermal protection like the Emisar would be nice though.

well yes but it is a very dumb idea to power this kind of light on and leave it unattended on turbo mode, its not meant for that stuff really.. The manual even says the light gets very hot quickly.

Except that it is advertised as having thermal regulation. Mine hit 199.7 degrees in testing, that’s clearly unregulated.

Wellp, it’s like a car with a 500hp engine. You can get nice acceleration right off the line, but you can also get stoopit in a hurry and go sliding off a curve into a ditch.

Thermal stepdown should be a true thermal stepdown, not just via a timer, even user-selectable. Think unattended in a room vs walking outside in subzero temps.

Ideally, you want a temp sensor right on the mcpcb, right next to the LED. Then sense the actual temperature and use a decent PID algorithm to step down to a max temp. You don’t want a sudden drop in brightness, nor any oscillation between bright and dim, but set it like a hotplate or soldering-iron.

Unfortunately, that requires a special mcpcb, special driver, special UI/code, etc., so it’s only for a truly custom design.

And yeah, people endlessly grexing about stepdown being too much, too soon, a dealbreaker, “useless”, etc., I wouldn’t want the headaches associated with designing it in except as a failsafe to keep the light/batteries from going supernova.

I get it and I’m an enthusiest and I know how to handle a light like this. But when it’s sold as having thermal regulation and it in fact gets hot enough to cause burns then it’s a problem.

It’s more like a car with a 500 horsepower engine but no cooling system. Sure you can take it out for short runs but if you drive it more than a few minutes it will burn itself up.

I don’t get it. It’s advertised as having thermal regulation, but doesn’t have it? And they were going to ‘sneak’ that by? Maybe it has it but it’s just not working right?

I’m not sure either. Hopefully mine is an outlier and the others don’t get so hot.

I get that, and a conflict between safety spex and actual operation is indeed a problem.

But most lights are handheld, and if you feel your hand starting to cook, you lower the power, so even a light with no/defective thermal regulation could still be “safe”.

Hell, I left my S2+ tailstanding to light a room via ceiling bounce, and couldn’t even grab it long enough to turn it off like 5min later. Dumb move on my part.

Make it a designed-in air-cooled engine and we can agree. At least with a temp gauge, you can see it’s cooking itself to death and back off… or keep driving it hard and watch it melt internally.

I had a waterpump blow its seal and start leaking coolant. No gauge in the car, just the idiot-light. Feathered the throttle the rest of the way to work. Air-cooled it enough to get the light off, only barely starting to glow on uphill runs.

Afternoon, topped it off with water (held), and made the whole trip home the same way. Idiot-light never even went on.

Point being, even a completely unregulated light can still be used safely with a little care and common sense. If regulation is off or nonexistent, yeah, that’s a problem if it’s specced to have it and be operational, but it still doesn’t mean it’s a fire-hazard unless it’s misused/abused.

Space-heaters can be perfectly safe… just don’t put it next to nice flammable curtains.

Where did you see that it was advertised as having thermal regulation? Can you show me the post? From my memory, it hasn’t ever been advertised that way on this thread.

I’ve always been wondering whether this has temperature regulation and low voltage protection throughout the group buy. Seems we’ve confirmed it doesn’t have temperature regulation but I still want to know if it has low voltage protection. Not having thermal protection to me is kind of a plus since I use the flashlight in my hand for practical purposes. But I do hope it has low voltage protection although I never really run my flashlights until its dead though.

Umm, I don’t know that, I was just looking at post 1342 …… and assumed. Perhaps I’m in error. My bad if so.

(wait, there it is on that diagram. Internal 55 degrees thermal control?)

I finally got an e-mail from Dale, my shipment did get caught in the HK warehouse for the duration of the Chinese new year. He offered to resend it or give me a refund.

I hope the rest of you with issues will hear from him soon, so you also can find a solution.

Thanks Dale & Terry

Same here. Got email shortly after my last post, now waiting on refund…

Just wanted to share something interesting. I just received my Pflexpro S2+ with triple Nichia NVSL219BT 219b 4000k emitters and OMG the tint is BEAUTIFUL! Much better than the many 219c 4000k and 5000k and even 219b flashlights that I have. Super good buy if you are interested in a well-built EDC with good customizable UI.
https://www.pflexpro.com/Nichia-219-…b-3up-3.8a.htm

Also I compared this light to the Haikelite MT09R XHP70.2 80+ CRI 4000k and surprisingly the tint was pretty much indistinguishable. That means if anyone wants to match the legendary perfect NVSL219BT tint in a high powered flashlight, swapping in the XHP70.2 4000k 80+CRI will do the job. The 4000k version of the MT09R is no longer available after the GB. So glad I got the 4000k version.

Aso Terry, I would like to request that Haikelite consider offering the XHP70.2 80+ CRI 4000k emitter as a standard option in future Haikelite flashlights and not just as a GB special. Having a high power lumen monster with the renowned Nichia NVSL219BT tint is just one of a kind awesome.

The lack of thermal protection is just a typical breakdown in manufacturing communication, I would guess. The light was planned to have it, but nobody told the programmer. Drivers done and shipping, programmer probably discovers the mistake, but decides to keep it quiet and play ignorant. Nobody tells the marketing or distribution people, light ships and the issue is not discovered until customers burn themselves an report it.
Welcome to the difficulties of managing a Chinese manufacturing process.

Good news is, my cells appear to have survived. I did a battery test on them with my opus bt-c3100 and they all still dishcharged over 3000mah.

So all is well. I’ll just be careful from here on.

At 55 degrees C it will step down from Turbo... If you double click and put it back in turbo it wil go back into it every time you do it.

I have tested it many many times for temp measurments and the highest I for was between 147 and 150 degrees F.

 

I am trying to understand why anyone would push a light just to see how hot it may get... There is a clear warning on the instruction manuel.

As far as the thremal programming you really would have to ask Dale.

LOL I am old school, once a light starts to get hot enough that I notice it it does not need to turn itself down, I turn it down.

I don’t think this should be underplayed. Given the range of other flaws, the fact something like this can be ‘forgotten’ makes me wonder just how safe these lights are, either for experts of those less experienced. What other electrical nonconformities are yet to manifest?

So far, from the GB batch, we have:
- underpowered lights (mainly the 35s)
- lights which don’t turn on at all
- lights which turn on a flash a few times and turn off
- lights which require the thread to be loosened to make a proper connection
- lights which don’t turn off (illuminating the button even when otherwise off)
- no indication of any thermal regulation
- moving goalposts about expectations of GB quality

Every indication was given that the quality of these units would be solid, and a rigorous QA process would be applied on every unit before dispatch. Unless somehow this all happened during shipping, I’m not sure what QA protocol could have been followed for this to happen.

For me, if I’m paying $100+ for a light, I expect it to work as advertised. I should not have to worry about me or my family burning their hands or shorting 4 18650s.

Here are a couple of beam shots from the 35 high I did a couple of days ago and I am just now getting caught up enough to post them... 

The first 3 minutes or so are more me talkng so move up to around 3 minutes or so and you will see some beam shots.

Now it is late Saturday night. I am going to clock out.

432yds, and a declaration that the XHP35 is a total success? How about the 1km claimed? Seriously, 432yds? My $30 UT02 will do that.

Friday night we tested my MT09R XHP35 Hi from this GB and a Haikelite MT07s. The MT07s has a bit higher range, but the beam of the MT09R is much wider.
My luxmeter shows 220.000 candela for MT07s and 196.500 candela (MT09R:6meter, Sony VTC6) for my MT09R (NW, but it looks like CW).
Our second luxmeter shows 27% more candela ! But my luxmeter compared with many other luxmeter and shows the same candela for many other flashlights like other TLF users had detected.
For example:
Astrolux MF02NW: 422.640 cd (6 meter, Samsung -30Q)
Acebeam K60: 144.000 cd (6 meter, Imalent MRB186-P30)
Imalent DT35: 121.320 cd (6 meter, Imalent MRB186-P30)
Jetbeam T6: 129.600 cd (6 meter, Imalent MRB186-P30)
Klarus G35: 195.000 cd (6 meter, Imalent MRB186-P30, is very sensitive with different batteries!!)
Utorch UT02 NW and CW: 86.000 cd (1 meter, with different batteries)

Is it even possible for triple XHP35 emitters CW to even reach 1000m range in this kind of light ?

After about how many seconds/minutes on turbo should it (70.2) step down?

You guys are wrong or maybe not doing it righ. Let me present you my observation.
Haikelite mt09r xhp70.2 CW. Use infrared temp to get the reading next to the switch.
All are in fahrenheit.. yes. This light have an automatic step down.

I turn on light to high mode.
Initial temp. 63 fahrenheit
1 min. 80
2 min, 93.5
3 min. 104
4 min. 110.5
5 min. 111
6 min. 111
7 min. 112.5
8 min. 113.5
9 min. 115.5
10 min. 115.5

I could feel step down after 3 min., slow shift. My eyes wouldnt notice. This light is not hot.. handle was 93. After 10 minutes, i double click. Then it go back go bright high mode.

Conclusion. My light have authmatic thermal step down.

I don’t quite understand. If there was a step-down after 3 minute as you say, why isn’t that recorded in your minutes/temp? Am I missing something? Thanks.

Newlumen, I think you are right. I think I just don’t notice the stepdown because the eye is not reliable for lumen measurements. Also mine gets pretty darn hot under extended use on max brightness but not dangerously hot like some people report here. I guess it may have some form of thermal protection. If that’s the case, then that makes this light even more impressive considering how much better it can maintain useable high output compared to other lights with thermal regulation.

I said i feel like the light step down after 3 minutes. My eyes couldnt tell. It was slowly step down.. i didnt see any flicks while the light step down..

I will do 10 minutes high test again on monday night using fully charged 18650, and i will also record lux number as well..

I know my light have thermal protection, because temp are 115.5 fahrenheit..
