I have a late-Friday post for you this week! This is the Fenix LD05 v2, an AAAx2 penlight. Read on for thoughts and testing!
Official Specs and Features
I’m not exactly sure how many version 2 of the LD05 there are. There’s definitely a previous version that has UV, but some documentation leads me to believe there might even be a v2 with UV. And there’s also a much warmer high CRI older version, too.
These are going for $39.95 right here.
This is a good penlight. It’s slim and appropriately pen-like. I like the TIR beam profile quite a lot, though I would really prefer a warmer and high CRI option, too. The UI is nice and simple, and the modes are decently spaced.

Package and Manual
Build Quality and Disassembly
The build quality here is good. Nothing too exceptional, and nothing bad at all. It’s very much like a pen.
Even (or particularly?) the clip is very much like a pen clip.
The driver is screwed into the head – should be fairly easy to access the internals, too. The tail end has a spring for contacting the negative terminal of the cell.
The threads on the head end are fine and long(ish) and unanodized.
There’s no knurling on the body, but there is some texture anyway.
Size and Comps
Length: 5.3” (135mm)
Diameter: 0.5” (13.5mm)
1.0 oz. (29.7g) excluding batteries
Here’s the LD05 v2 beside the Lumintop IYP365 – an AAAx2 light, with a reflector.
Retention and Carry
It’s a penlight, so you’d expect a pen-like clip and to carry this light like a pen. It doesn’t disappoint. The clip will allow this light to blend right in with your writing utensils!
The clip isn’t removable or reversible. There is no other way for carry of the LD05 v2.
Power and Runtime
I tested the light with two LADDA AAA cells. Performance with primaries should be approximately similar (and is expounded upon in the manual). Performance was good, but there appears to be no LVP whatsoever. Surprisingly High has a stepdown – I’d expect the light to maintain 150 lumens for longer that 5 minutes. But once it steps down to around 110 lumens, it’s exceptionally stable.
The output on Medium is basically unregulated, and shut off when one of my cells tripped, or was overdrained, or.. something. The voltage was zero, whatever the case.
There was also no evidence whatsoever of LVP on bench power.
Modes and Currents
These claims are for NiMH. Alkaline have slightly different claims.
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps (@3V)|
No PWM on any mode! Great!
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. And here’s the worst PWM light I have ever owned. Also one of the very first lights I ordered directly from China!
User Interface and Operation
The switch is a single tail mechanical reverse clicky. It’s quite clicky, easy to actuate, and has a nice metal cover.
This metal cover allows tailstanding somewhat, but not all that reliably.
Here’s a UI table!
|Off||Click||On (Mode Memory)|
|On||Press (or “Tap” without clicking)||Mode advance (ELMH)|
Very simple UI right there. Very simple.
LED and Beam
The only place I could find information about the emitter was in the manual (not mentioned on the website!). It’s apparently a Cree XD16 S3, and in cool white format. The emitter is behind a TIR, and gives a nice spot output.
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
Test light is on the left!
I compare everything to the KillzoneFlashlights.com 219b BLF-348, because it’s inexpensive and has the best tint!
What I like
- Good build quality
- Very simple UI
- Includes cells
- Great beam profile
What I don’t like
- No LVP
- CW only
