Acebeam H40 LED Headlamp

Different Tint Options

The Acebeam H40 is the newest headlamp in the H series from Acebeam and right out of the gate has two different tint options: Cool White and Neutral White. The Cool White version is powered by a CREE XP-L HD LED for a maximum 1050 lumen output that offers a peak beam distance of 117 meters. On the other hand, the Neutral White version (no longer available) offers a Luminus SST-20 CRI 95+ LED offering a true to life color range as well as 600 lumens and a peak beam distance of 128 meters. The Neutral White version casts a warm and soft beam that is equipped to resemble sunlight, reducing eye strain and making it an ideal headlamp for photography. Both options are ideal headlamps for workers, campers, hikers, spelunkers, photographers, or fisherman.

Reliable Power

Powered by a single AA battery, the Acebeam H40 can be powered by alkaline, Ni-MH, or Li-ion chemistries for ultimate versatility. Not to mention that the H40 features an infinite High to Low output, as well as lock and unlock modes for variable lighting in any environment. The H40 makes it easy to adjust to dark caves, hikes at dusk, or night fishing.

Really like this headlamp.

November 30, 2020

I got one of these in neutral white for working around the house and working on vehicles. I wanted a reasonably lightweight light that is powered by regular or rechargeable AA batteries and this one fills the bill.
It's light enough that the first thing I did was cut off the strap that goes over the top of your head because I have never liked it on the headlamps I own that have it. It is necessary on a heavier lamp, but this one is light enough that I haven't missed that strap for one second.
The color temperature is perfect, but the beam is a little bit too much spot and requires adjustment from time to time to get the beam where it needs to be. To me the tradeoff is worth it. I haven't tried a lithium battery in this one and probably won't because it's bright enough with an alkaline or nimh AA for my uses. I have other, brighter headlamps if I need a brighter beam.
The stepless UI is simple and perfect, and the firefly mode is nice as well.
I'm not really fond of the giant ACEBEAM logo on the headstrap, but that's not really a big deal.
Might have to give the cool white version a try some time.
