nice looking light and love the High cri option .

Now all BLF needs is a promotional deal

I like it, my favourite headlamp is a Thrunite TH20, and this is quite like it, plus added dimming via a ring instead of by holding the button, nice!

Why a 5 lumen high “moonlight” mode Acebeam? If you want to make a good backpacking light it should have modes below 0.1 lm, 5 lumens is waaay to high for preserving night vision.

Why a 5 lumen high “moonlight” mode Acebeam? If you want to make a good backpacking light it should have modes below 0.05lm, 5 lumens is waaay to high for preserving night vision.

Preferably green as the eye is most senistive to that color.
Added bonus: Green doesn’t attrack bugs.

A secondary green/red emitter would totally ruin the idea behind this light and raise the cost significantly. Would it have a decent moon, eg. 0.1lm or lower it would be a competitor for the classic Petzl headlamp, but now it’s not.

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.

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.

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.

ACEBEAM:

H40 headlamp

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

Ryzbor:

why no moonlight?

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.
