Fenix have released the headlamp HL10 2016 Edition, with Philips LXZ2-5770 LED installed, powered by 1xAAA. It will give you both spot and flood beam, adjusting the front rotatable lens. Although it's a headlamp, it can be used as a key-chain light, if you want.

The light comes in a clear plastic container. It comes with a headband, spare o-ring, key ring, 1xAAA battery, user manual and warranty card.

Like the HL10 2013, the HL10 2016 headlamp is a light and holder structure. You can use it as a key-chain light.
.
.

The hard plastic holder is composed of a clip holding the light and a bracket for headband. The clip holds the light fairly firmly, but it seems there may be no risk of scratching the light when pulling it off or fitting it into the clip, as the material is plastic.

You have three body color options available (i.e., gold, black and lilac). My review sample is gold. I'm not sure the anodizing is hard type III, but it's a matt gold and consistent throughout with no chips or blemishes to be found on my sample. Labels are fairly minimal and not as bright as other lights, but clearly legible against the background. There is no anti-roll indentations on the body
.
.

The light has 2 parts (i.e. integral head-battery tube and tailcap).
.

You can see some differences between the HL10 2013 and the HL10 2016.
.
.
S-7.jpg


The light has electronic control switch on the head. The switch cover has a textured grip, and is slightly protruded. Like the HL10 2013, it has a firmer switch feel, requiring a definite click to activate. The switch is easy to access. Feel of the switch is good for this type, with a lightly audible click as you make contact. The positive contact in the head has a physical reverse polarity protection. There is a rotatable lens which is plastic.
.

There are the beam pattern marks (i.e., flood and spot beam) on the rear part of the body, and you can select the beam pattern, rotating a detent on the rotatable lens.
.
.

The battery tube has a clean cylindrical tube design with four flat faces machined on where manufacturer name, model name and serial number are printed. There is no knurling on the tube. Unlike the HL10 2013, tail threads are anodized, so tail lockout is possible. Base of the tailcap has a simple spring.
.
.
S-10.jpg


The screw threads are good quality triangular-cut. My sample has no lube on the threads. But I haven't experienced any problems with cross-threading. It is difficult to unscrew the tailcap and change battery when the light is mounted in the clip of the holder.

.
.
S-11.jpg


The rear end of the tail cap has a tiny hole for split-ring attachment. It seems to be stronger than the HL10 2013, as it is slightly farther to the edge. The HL10 2016 can tailstand, without the split-ring attachment.
.

There is a stopper for adjusting the strap. The headband is good quality, and worked well in my testing. It holds the headlamp securely (both within the holder, and strapped to your head), but still allows for accurate positioning. The headband may fit to those who has large head size, as its length is longer than the HL10 2013.
.
.

The angle adjustment is 360 degree (i.e., the light can rotate freely in the clip) and the light is not moved at any point during use.

.
.
S-19.jpg


The HL10 2016 is very small, and its weight is lighter than the HL10 2013.
.
.
S-20.jpg


The light itself is very compact. The wall thickness of the tube is 1.3mm (i.e., almost the same as the HL10 2013). The light feels solid. The use of Li-ion 10440~10450 rechargeable is banned. The build quality is excellent.
.
.
User Interface

HL10 2016 has the same UI as the HL10 2013.
There are three constant output levels only (i.e., no flashing mode).
The light is turned on/off by pressing and holding the switch for 0.5 seconds.

Give a quick click of the switch to advance through outputs when on, which proceed in sequence from Low -> Med. -> High, in repeating sequence. The light has mode memory, and remembers the last output level used when you turn the light off and back on, (even after a battery change).
.
.
Standby Current Drain

Due to the electronic switch, there is going to be a standby current drain when a battery is installed. I measured this current as 14.8 uA that is the same value as the HL10 2013. Considering Eneloop AAA (750mAh) capacity, that would give you around 5.8 years before fully charged battery would be completely drained. As there is tail lock-out feature, the drain is absolutely nothing to worry about. As usual, I recommend you keep a battery separate from the light when not in use for a long time.
.
.
PWM
S-21.jpg

The lights show no sign of PWM at any output level. The light is constant current controlled. I notice there is no buzzing sound at any levels.
.
.
Runtime
The runtime to fall to 10% of its initial output from 30 seconds after the point the light is first turned on (i.e., based on ANSI FL-1) for High is as follows :

S-22.jpg


As expected, the higher capacity cell gives you extended runtime. The light maintains perfectly flat regulation for an extended period, before dropping output through High on both two different chemical batteries. The difference is how long they last before falling out of regulation.

Beamshot

As you can see, the HL10 2013 is all flood. The HL10 2016 with flood beam smooths out the hotspot and gives you less spill, in my view. It seems there is not hugh difference between the spot and flood beam in a very short distance as above. The overall beam profile is good. The tint is very close to neutral white on my sample.

2. 3.0m Indoor Beamshot on max. output on 1xPanasonic Eneloop AAA (750mAh)

One thing I find interesting is the low level runtime on nimh is longer than alkalines.

I expect that as Ni-MH gives much longer time than Alkaline on High. Thanks for your information. Lynx_Arc!
Actually most lights I've seen give longer runtime on high with nimh and shorter on runtime at the lowest (sub 10 lumens) levels with nimh as alkalines have the most capacity at lowest current levels of the two chemistries.

Ah! That's exactly right. From the HKJ's excellent tests, Fujitsu alkaline G+ AAA gives you much more capacity than Eneloop AAA HR-4UTGB (750mAh) at 0.1A current. The former has 717mAh and the latter has 1,066mAh capacity. It seems Alkaline cells are quite appropriate for lower current.

Just have to wait till someone with equipment can verify what is going on here. 2 extra hours at 4 lumens (or perhaps 10% of that) when you already have 24 hours of use isn't a huge deal as one can pack a handful of extra AAAs to easily make up for the difference. I've found that low modes are most useful to save the battery for when you do need the higher modes.
If you run on high for only 6 minutes it uses up about 2.5 hours of the low runtime power while 6 minutes at the low level only uses up a 12 seconds of runtime on high.

Thanks for the review. I'm considering getting one of these and finding a clip to carry it in the shirt pocket.
