Infinitely Variable Brightness 1 x AA Headlamp 1050Lumens

The lowest mode on the TH20 is 0.14 lumen :innocent:

Same question. In other words, how long to kill a battery if the light is left turned off?

I realize the marketing accounts won’t know this kind of thing. But this really needs to be a 2-way channel that reaches the engineers/designers.

Hear us!
This $35 headlamp should span the range from 0.1 to 300 lumens, be available in any tint we demand, be PWM-free, run custom firmware that can easily be reflashed, and we demand a direct line to the engineers who designed this!
Then, and only then, will we consider buying it!!!

OK, just kidding. But be aware, if posting your lights in a flashlight forum be ready for triggered flashoholics going ape over a 5 lumen ultra-low.
And it DOES look like ACEBEAM checks the forums because this is offered in sst-20 95+ CRI

I’ve got one in the cart at illumn, just looking for some more stuff to get it up past free shipping. 1xAA headlamps are handy!

Thrunite gives you a good low mode. Acebeam gives you a good emitter. Either could do both and immediately become the community favorite.

Agreed. I really don’t need anything more in a headlamp than what my Thrunite already provides save a mod or soon to come(?) emitter upgrade…which Acebeam must figure is more than enough to make me forget about a proper low mode.

Wrong.
(Edit: one of their distributors made me forget about ‘proper anything’ by offering 15% off through Amazon versus whoever…‘sold’ to an obvious flashaholic).

Acebeam, can you confirm if the light has regulated outputs?

Just ordered the H40 SST-20 4000K 95CRI from Amazon for $29.80 (no tax and free shipping). I like that the weight is only 34 grams (sans battery). The Thrunite TH20 is over twice that weight (76 grams).

4000K per the Amazon description linked above.

Thanks, Al. Good point and price. Not sure who competes at that CRI/output/throw(?)/weight/price point in a headlamp nowadays.

Thanks ActiveAl I just bought the same one……
Can you link me to some Ni-MH cells please….thanks

Woah, thanks for noticing the weight difference, ACTIVE AI!
I’m holding off until I hear something about PWM. I don’t care if a light uses PWM but I’ve gotten some budget lights that it’s hard to tell if it’s pwm or a fast strobe.
(And yes, I’m sounding like the picky flashoholics I described previously but at least get the frequency higher than the <$10 lights!)

I recommend Eneloops if you can afford them - they have great longevity. This eight-pack of AAs at $18.99 is not too bad.

That “buy with 1 click” button is dangerous…

…agreed.
We rightfully complain that OEMs simply don’t ‘get it’ in terms of the most basic of inexpensive features needed to corner a particular market.
Immediately, one of their distributors lops off 15% while using a much more palatable and familiar distribution channel…sold.
With that said and in my opinion, TH20s will remain the suggested choice for relatively inexpensive/give-it-a-try AA headlamp hosts in an ever changing LED market over but one critical feature…low output.

Sucked in again.

Just PM'd Acebeam this question:

What type of regulation (for example, constant current or voltage) is incorporated into the HC40? Thanks!

It will be interesting to see what kind of reply (if any) I get.

But note the constant lumen output (except in Turbo mode) per LED for all three battery types.

Doesn't this indicate some form of regulation? It would be nice to know the specifics.

Why is ACEBEAM statrting another thread on the same subject? There are still plenty of unanswered questions in the previous one, including my question about runtimes:

Good question and catch.
Perhaps similar unanswered questions or those involving members ever taking control back of this forum have something to do with the following business attitude prevailing in our soon to fail trade negotiations:

I would keep the significant questions coming until they are all answered in every single thread or expect nothing different.

Hmm. This might be my first AceBeam purchase. I love everything about my Nichia Manker E03H except long-press for off. Anybody have both and can compare the two?

Edit: It would be nice to have the emitter in the center, instead of offset, better firmware on the AceBeam, and better low modes with a 14500 all look like advantages of the H40 (to me, anyway).

And from what I’ve read, AceBeams are generally higher quality builds than most Mankers, right?

Well ya’ll talked me into one. I don’t even need a headlamp. :slight_smile:

I’m skeptical. I suspect Thrunite is giving the weight with the headband and Acebeam is giving the weight without it. Parametrek shows a 1g difference between the two with NiMH battery and headband.

…at least you didn’t say (here) that you wouldn’t buy it…and then bought it anyways. :person_facepalming:

I’ll put you down for not needing one because you never had one…just because it sounds better. :slight_smile:
