Light Review: Fenix WT16R and WT20R

I’ve always liked functional lights, those lights that not only give you light, but give you various options for positioning and types of light. Typically they are not the mega-lumen monsters, instead with more modest outputs, but with a focus on utility. One of the latest releases from Fenix is the WT16R which compliments the existing WT20R model, and this detailed review is of the Fenix WT16R and WT20R from the ‘WT’ Work Light series.

A ‘First Look’ Video of the WT16R and WT20R:


A good look round the WT16R – Things to look out for here are:
The WT16R on test is actually a pre-production model (but of the final construction), so did not have any packaging. It has a fully fixed body where nothing moves or opens, and has a non-removable built-in USB-C rechargeable cell. The WT16R has a main spot beam at the front and a large side panel to provide area flood lighting (and a flashing amber option). A clip and two magnets allow for various mounting options, and the design allows for free-standing use as well, plus it definitely won’t roll away.


A good look round the WT20R – Things to look out for here are:
An articulated head, how I love an articulated head. The WT20R has me straight away on that one alone. But then it much more; look out for the illuminated side switch, metal bezel, twin beam types and dual-fuel ability with the supplied li-ion and you can also fit it with AAs (not provided).


The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

The indoor beamshot is intended to give an idea of the beam shape/quality rather than tint. All beamshots are taken using daylight white balance. The woodwork (stairs and skirting) are painted Farrow & Ball “Off-White”, and the walls are a light sandy colour called ‘String’ again by Farrow & Ball. I don’t actually have a ‘white wall’ in the house to use for this, and my wife won’t have one!

For each of the following galleries the exposure was set to the same to directly compare the two beam types from each light.

(The WT16R’s flashing amber mode is not represented here.)


WT20R Beamshots


Batteries and output:

The WT16R runs on a non-removable built-in USB-C rechargeable cell, and the WT20R is supplied with a USB rechargeable li-ion cell but can also use AAs.

Please note, all quoted lumen figures are from a DIY integrating sphere, and according to ANSI standards. Although every effort is made to give as accurate a result as possible, they should be taken as an estimate only. The results can be used to compare outputs in this review and others I have published.

Note the Parasitic drain of the WT16R cannot be measured, and for the WT20R the li-ion and AA values differ slightly. Also note that when using AAs, the WT20R cannot output on High.

The following gallery has the lumen output graph and USB recharging trace for the WT16R first, then the WT20R. For the WT16R the two traces are the spot and flood beam outputs, and for the WT20R the two traces are for the (higher output) flood beam, but powered with the supplied li-ion cell and then AA Eneloop cells.


The WT16R and WT20R in use:
This gallery actually says without words most of what I want to say, so let’s start with that…


The first of those images shows the WT16R using its tail magnet to give downward facing hands-free lighting from the side panel flood light, along with the WT20R aiming at another area. Then the WT16R on the front of a boiler lighting up the control panel. Remember there is also a second magnet on the clip, so if you needed to tuck the WT16R up under something you can do this as well. Similarly you can use the spot beam if you need the light concentrated in a smaller area.

Onto the WT20R and its articulated head. The gallery has a photo showing the extreme angle range the head can be moved to, it is not just 90 degrees of motion, but 105 degrees of motion from fully straight to a slight downward angle when tail-standing it. Combined with the magnetic tail, the WT20R is a superbly ‘aim-able’ light. You can mount/stand it and then angle the head to put the light exactly where you want it, easily and quickly. You even have a choice of flood or spot beams as well.

These are true ‘working lights’. They are illumination tools, and designed such that you can use them hands-free and put them into difficult locations which you might not be able to with a headlamp.

Using side switches makes the controls very natural to use, the only minor comment I would have on this is that the side the power switch is on is better suited to right-handed use. When using the WT20R with head angled, or the WT16R’s side panel light, for left-handed use this means either using a finger curled round underneath, or a slightly switch on and twist round action. This minor point is unavoidable really, so is not a criticism, more of a consideration.

If you have one or both of these you will wonder why you struggled on with a normal light for so long, when these make mobile task-lighting a breeze.

Light Review: Acebeam L35 – 5000 Lumen Tactical Flashlight

For me, finally, the long awaited arrival of an Acebeam L35. In fact, for this test sample I had given up all hope and written it off as lost, but amazingly it did arrive, only five months late! (courier issue, not Acebeam) Clearly it was meant to be (eventually), and as with all Acebeam lights I have tested, immediately showed its mettle. Join me in this belated review of the Acebeam L35, a 5000 Lumen tactical flashlight.

First Look Video:
This is a first look Review of the Acebeam L35 5000 Lumen Tactical Flashlight. ‘First look’ as at this point I had not carried out the full technical testing and output traces.


With the box being destroyed in transit, it is not shown. This is what was in the package when it arrived.


A run round the holster:
A quick run round the L35’s supplied belt holster.


Details of the L35 – Things to look out for here are:
The L35 has a nice large head which really aids the handling, an interesting spiral pattern grip on the tube, tail and side switches, plus a double-walled battery tube to provide an extra control signal connection.


The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

The indoor beamshot is intended to give an idea of the beam shape/quality rather than tint. All beamshots are taken using daylight white balance. The woodwork (stairs and skirting) are painted Farrow & Ball “Off-White”, and the walls are a light sandy colour called ‘String’ again by Farrow & Ball. I don’t actually have a ‘white wall’ in the house to use for this, and my wife won’t have one!

Even though not a LEP light, the raw power of the 5000lm output does create a visibly projected beam.


Batteries and output:

The L35 runs on a USB-C re-chargeable 21700 5100mAh cell provided with the light.

Please note, all quoted lumen figures are from a DIY integrating sphere, and according to ANSI standards. Although every effort is made to give as accurate a result as possible, they should be taken as an estimate only. The results can be used to compare outputs in this review and others I have published.

Also included here is a charging trace for the 21700 cell and a zoomed in runtime trace to show the first part in detail.


The L35 in use
We are all very used to tactical lights being based on the single 18650 / 2x CR123 framework, so the L35 might seem to be going in the wrong direction. For me that is not at all the case. The body is very comfortable to hold, the larger head give the L35 some presence and a stable front end to stand it on.

The ‘Ace’ delivered here is also the function provided by a tail and side switch. Making the tail-switch a dedicated maximum output switch, provides the true ‘tactical’ simple high output. The side-switch then delivers the rest – the more usable set of modes and ergonomic handling, for low stress situations. A really usable combination of modes and controls.

In an ideal world, the ‘moon’ mode could be a little dimmer. It’s not blinding with dark adapted eyes, but it is a little more disturbing for anyone you want to leave sleeping peacefully.

Talk about blinding – maximum output. Instant access to over 4000 lm from a small light (4769 lm at switch-on), it certainly is impressive and overwhelming at close range. But look at the runtime graph and you see that output (as is typical) dropping immediately, and by 60s from turn on you have 1500lm. So the headline figure is short lived and mainly available as an instantaneous blast.

There is nothing wrong with this as you have to manage significant heat output and the L35 is not a big light, so there is not much thermal ballast, the 5000lm figure is always going to be in short bursts. Despite this, it is a solid performer and you will soon realise that you actually rarely want that much light when you are also right there next to it.

With the side switch, and output level memory, the L35 also becomes a superb every day light. Pick you favourite output mode and a single tap to access it. I know many swear by tail-switches, and they have their place, but for every day tasks, the side switch gives you a more natural way to hold it.

Although the L35 can’t tail-stand, it has enough leakage due to the bezel crenellations, when head-standing that you have a gentle background light. I’ve found myself using this quite a bit, but being careful not to use anything other than moon, low or mid1 just in case it heats the desk too much.

It is a bit bigger than my typical EDC light, but moving to a new phrase I’m coining, it is an excellent EDU (Every day use) light, and I’ve made space for it.
