Urflamp C6 Right Angle Flashlight Review
The Urflamp C6 right angle flashlight offers a lot! USB-C charging, a sensor for hands-free operation, a complete package including 18650, and more. Read on!
Official Specs and Features
Here’s a link to the Urflamp C6 right angle flashlight product page.
Versions
There’s just one version of the Urflamp C6 right angle flashlight but it’s available as a “right angle” light or as a package, including the headband – in that case, they call the C6 a headlight. Same light either way, but one has more accessories.
Price
The Urflamp C6 right angle flashlight sells for %65, and that includes the cell shown in this test. For another $16, you get (at least) the headband, which you can also see below.
What’s Included

Package and Manual
Build Quality and Disassembly
Despite Urflamp being a new brand (at least to me), and having an unusual name (at least to me), the C6 enters the market seeming like a mature product. Build quality is very good and the light feels solid. The Urflamp C6 right angle flashlight lacks some of the things (shortcuts? cheaper options?) a new brand might use.
For example, the anodizing on the Urflamp C6 right angle flashlight seems great!
While these openings in the head might be considered cooling slots (and they are, sure), they also seem perfectly sized for tritium vials, too! This somehow doesn’t seem excessive, despite the rest of the light being fairly unadorned. But even if you don’t decide to fill the light with tritium, these at least serve to aid in cooling.
The tailcap (and only the tailcap) is removable. Threads are anodized, appropriately lubed, and not overly long. This is a nice setup!
There’s a magnet in the tailcap too, which you could probably remove by removing that spring first.
Inside the cell tube you can see the positive contact – just a button (no spring.)
Size and Comps
107m x 24mm and 123g (with cell).
If the flashlight will headstand, I’ll show it here. If the flashlight will tailstand, I’ll also show that here too!
Here’s the test light with the venerable Convoy S2+. The version below is a custom laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full post on an engraved orange host right here! Or go straight to GadgetConnections.com to buy your Convoy S2+ now!
In the photo above, you may note that the SRM (standard reference material) flashlight for comparison has changed! I used a TorchLAB BOSS 35 for ages. Now what you can see as the 18350 SRM is the Hanko Machine Works Trident. While I have not reviewed or tested the Gunner Grip version seen here, I have tested a Hanko Machine Works Trident Total Tesseract in brass. I love the Trident, and it’s a nice juxtaposition beside the inexpensive Convoy S2+, which I also love to use as an SRM.
Retention and Carry
The Urflamp C6 right angle flashlight ships with a pocket clip installed. The clip attaches to the head end (only) but is a two-way clip. It’s versatile.
A lanyard is included, but it attaches only to the friction-fit pocket clip. Maybe not the most ideal connection.
If you opt for the headlamp version as I did (or as Urflamp did for me), you’ll get the headband seen below.
It’s a stretchy band and has an over-the-top connection too.
Unusually, the whole band has silicone grippy bits on the back.
It’s possible to remove the top strap.
Weirdly the headband connection (while secure) doesn’t necessarily seem made for this light. There’s no groove on the tail end to accept the headband strap, for example. This is also what I’d call the “old type” of headband connector – more companies today use clip in hard plastic connectors (and I prefer those.)
In the tailcap is a strong magnet, too.
Power and Runtime
The Urflamp C6 right angle flashlight ships with a 3800mAh 18650. It’s a standard cell, too, so you can likely use any button top cell.
The 18650 goes into the Urflamp C6 right angle flashlight in the usual way – positive end toward the head.
Below are a number of runtimes. I tested Turbo twice (because I forgot to connect the temperature sensor on the first one). They should be nearly identical.
I appreciate the regulation on all modes.
The switch does indicate when the cell voltage gets low and the light eventually shuts off. The switch will also indicate the power level right after the light is turned on. Levels are as follows:
Green: ≥90%
Green flashing: 40% to <90%
Red: 15% to <40%
Red flashing: 0% to <15%
Charging
The Urflamp C6 right angle flashlight has built-in USB-C charging. There’s a charging port on the head.
I forgot to show it anywhere other than the intro photo, but there’s a press-in cover for this port, too.
Urflamp includes a C to C charging cable.
Charging via A to C or C to C is fine, and both peak at around 2.4A. That’s quick, but still well under 1C for this 3800mAh 18650.
While charging, the switch is red. When charging is complete, the switch turns green.
Powerbank
The powerbank (or “reverse charging”) option works fine. I tested C to C and the output can go up to around 2.6A, but has a more stable voltage around 2.2A. It should work fine for emergency charging a phone!
The cell is 3800mAh though, so you won’t charge a bunch of things on one pass. It’s very acceptable for emergency situations, though.
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps |
|---|---|---|---|---|
| Turbo | 2000-600 | 10s+4h | 1496 (0s) 1409 (30s) |
6.11 |
| High | 1000-300 | 60s+18h | 803 (0s) 777 (30s) |
2.74 |
| Medium | 300 | 19h | 235 | 0.67 |
| Low | 120 | 24h | 97 | 0.25 |
| Eco | 5 | 489h | 0.7 | [low] |
Pulse Width Modulation
None of the modes use PWM.
Here you can see a “baseline” – a chart with almost no light hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.
User Interface and Operation
There’s a single e-switch for controlling the Urflamp C6 right angle flashlight. There’s another option though!
The head has a sensor! In fact, Urflamp uses this feature right in the product name – C6 Sensory Right angle Flashlight.
The e-switch is fairly proud and “domey.” Action is deep and really not my favorite. I’d prefer a flat button.
The switch also has an indication feature – it can be red or green. Both colors can blink, too.
Here’s a user interface table!
| State | Action | Result |
|---|---|---|
| Off | Click | On (memory except Turbo, SOS, and Strobe) |
| On | Click | Off |
| On | Hold | Mode advance (Lowest 4 modes) |
| Any | Double click | Turbo |
| Turbo | Double click | Return to previous state (except if double click was from “off,” in which case double click returns to memory) |
| Any | Click 3x | Strobe |
| Strobe | Click 3x | SOS |
| Strobe or SOS | Click | Previous state (from before strobe group) |
| Off | Click 4x | Lockout (blinks 3x to indicate lockout) |
| Lockout | Click 4x | Unlock to ECO |
| Lockout | Click | No change |
| Off | Hold | Turns on sensor (indicated by “breathing” green switch) |
| Light off but Sensor on | Double wave | Iterate flashlight on/off |
| Light on and Sensor on | Single wave | Mode advance (lowest four steady modes only) |
I don’t usually care too much about motion sensors for operating lights, and that’s true here too. This one does seem to work well, though, and I appreciate that.
LED and Beam
Urflamp says the emitter in the C6 is a Luminus SST-40. The emitter has a TIR that provides great throw, too. It’s a nice combo!
The beam is very tight!
LED Color Report (CRI and CCT)
I don’t believe Urflamp makes a claim about the CCT but it’s fairly reasonable – in the low 5000K’s. Neutral to cool, which is not too bad. The CRI is low, in the mid-60s and notably, the Duv is “positive to very positive” making a greenish beam. The green beam is most notable on the lower modes, which you can see below.
Beamshots
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level and the beam hits the ceiling around 9 feet away.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right. These photos are taken around 18 inches from the door.
I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
Summary and Conclusion
The Urflamp C6 right angle flashlight pleasantly surprised me. The build quality is great. Urflamp does have a bunch of other flashlights, so it’s not a totally new brand (or at least this isn’t their first light), so it’s no surprise that the C6 is fairly mature. There are a lot of things to like here, including great throw (and a tight beam) as well as a reasonable user interface (other than mode memory and no option to start in Eco). The headband and other features like the sensor are all very good, too. At $65 (or $81) there’s going to be a lot of very good and familiar competition, but the Urflamp C6 right angle flashlight does bring the goods!

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.
What I like
- Great build quality
- Lots of features
- Sensor works well
- USB-C charging works well too
- Can work as a powerbank
- Reasonable user interface
