It sounds like the same ramping UI as their TH20 headlamp. Strange that they list runtime at specific lumens. Also strange that high at 50% doesn’t get much more run time than turbo. But the price, size and likely performance probably make this one a winner. A pocketable wall of light. I too am curious about step down on high.
Correction: It’s not ramping. The light cycles through low/medium/high. If it can maintain 1,800 without step down this light is a hands down winner. If not, 320 is a long way down.
Please post your impressions when you get the light. I’m very interested in this one.
Will do. To be honest, my impressions will be basic. I just don’t have the patience to write detailed reviews.
Basic is fine. Real world impressions are great.
Mine arrived yesterday and it is DOA. Flashing purple light when I try to recharge internally (and yes, the plastic thing is removed). Doesn’t work with an Imalent 26650 or an Efest 26650 either
Well that’s disappointing. The specs have so much promise.
That sucks. Mine hasn’t shipped yet.
Yeah, depressing! I was wondering if this first batch might have some bugs like some 1st generations do.
I hesitated buying this light because I don’t care for built-in chargers mainly because of the rubber charging port covers which could become an issue with use.
I only own one light with a built-in charger and the charger was DOA upon arrival.
Still no word on the one I ordered.
Mine shipped today. Since it’s coming from New Jersey, I should have it in a day or two.
EDIT turns out that the battery tube was shipped installed the wrong way. Once I put the non anodized end towards the tail of the light, it worked fine. Nice and bright. UI is the same as the Thrunite TN4A
Well, that’s great! Good on you for figuring it out!
Is the light overall seem quality built? Does the rubber cap over the charging port seem stout and quality?
It was a total fluke that I figured it out. Build quality is very good, typical for Thrunite in my experience. Rubber cap seals well but time will tell if it lasts. Charging rate was at least 1.5 amps via the usb port. Feels solid and works well. A little bit of battery rattle and the lens makes the same sound (tinking sound) as the MF02 when it is heating up. 5000mah battery included. Overall, very happy

I just used the code for purchase today! Thanks for the heads up everyone 
It came and it works perfectly so far. I’ll put it through it paces later. I’m charging it now.
BTW, it comes with a lanyard, a belt pouch holster, 2 spare o-rings, a spare USB cover, and a spare rubber switch boot.
It’s a beauty.

It’s nice it comes with a spare usb cover.
i got mine last night. It’s smaller than i thought and the NW tint is good.
Wow, I missed that. Very nice!
