New Arrival-1xAA High Performance Headlamp-H40

Something does not sound right here.

I love AA headlamps. I do like ramping but not by pressing a button. I like control ring brightness ramping.

Now to decide whether to get XP-L or SST-20… Now I am waiting for the promotional code.

oh heck I need one of these!!! need a code!

I guess most people want to see something in the dark…

gimme da lite!

Are the highest step down outputs and below (350 lumens li-ion & 250 nimh) regulated? Or will output decrease as battery voltage drops?

I can light my entire bedroom with the ceiling bounce of the 0.07 lumen mode on my ZL. It can also reach across the longest part of the upper floor of my house with a usable amount of light. When your eyes are dark-adapted (and you want to KEEP them that way) 5 lumens is far too much and much less it required to see fairly far.

CRI95+

So having a Zebralight means you are forced to use the 0.01lm mode? Even 0.5lm is quite a lot of light if you want low light or want to be discreet. For me 0.01lm is more then enough for navigating through dark rooms an my eyes aren’t even that healthy.

Answers for post #8 and #13? Thanks.

My favorite as well for the price/feature set. This light needs to be priced right for me (somewhere) with high CRI being my only differentiating feature, the TH20 being significantly less expensive and its ability to ramp down to 1.6 lumens.
Way too much competition out there for these lights to be inching up in price without the desired features as they have been of late, imo.
Honest comparisons here are the only way to stop this nonsense as somebody has been doing of late to at least snap the world back in to reality.

MSRP Price 34.30 USD (on Acebeam website):
is this for regular version, for high-cri version, or both?

Acebeam: please do add a moonlight mode (<1 lumen), or even better firefly mode (< 0.1 lumen). This will broaden the appeal of the H40 to a wider audience, while it will not deter people from buying it.

Is there more info on how the rotary interface works, e.g. magnetic?
I like the idea of rotary interfaces, however the specific implementation on my Imalent HR20 feels quite fragile…

When will this be available in the US ?

Why is that?

Both a 14500 Li-Ion cell and a AA NiMH cell have about the same overall energy when delivering low current, so you would expect them to have similar runtimes if lumen output is the same. Therefore, one of the following is happening:

1. Light output on NiMH is actually lower than on Li-Ion
2. If light output truly is the same (5 lm), then the above runtimes are wrong.
3. If light output truly is the same, and the above runtimes are correct, then this driver is wasting a lot of energy when running on lower mode when using a Li-Ion cell.

Looks like a great AA headlamp. I have the Acebeam H30 and while I like the 21700, high output, and form factor, I don’t prefer the CW tint and don’t need the green/red emitters, which I’m planning to swap out in the future for Nichias or Optisolis 2000k and 5700k.

Also what tint bin is the SST-20? I hope it is not above the BBL again. I have the Acebeam EC65 219C version and I don’t like the greenish tint so I won’t use it until I swap the emitters. Otherwise it would have been a great 21700 light.

The website seems to indicate a ramping mode of 20-230 lumens, with an “ultra” low of 5 lumens and a turbo of 350/1050 lumens or 250 lumens. It also mentioned ramping controlled by a single button. So I guess no dial. :frowning:

My impression from reading spec sheets of various lights is that this is pretty common in the 1AA and 1AAA lights. The Li-Ion just don’t seem the have the low output longevity that NiMh have.

If I had to guess, actual lumen on low when running on li ion is higher than when running on nimh. I have yet to see an AA light that has the same output moon mode on both li ion and nimh.

So is there a promo code Acebeam?
