The urFlamp V63 started off as a Kickstarter project, with a few unique features, including a extendable battery tube as well as a screw-on adjustable magnetic base.

The extendable battery tube is a little unique, but has already been offered by 1 or 2 other flashlight brands in the past.

At the time of writing, there are 2 versions of the V63, namely the V63 Floodlight, and the V63 Spotlight. And the one I am reviewing here is the latter.

The Floodlight is using 3 LEDs for max brightness, and the Spotlight is using a single LED for maximum distance. And from specs, this sounds like a pretty interesting offering, so let’s see how this one actually performs. Because, like you probably know, we don’t

Package quality.

The flashlight arrived in a generic carry case, with the following inside:

• The flashlight : urFLAMP V63
• Storage case/bag
• Lanyard
• 2 O-rings
• Magnetic base (which seems to be optional)
• USB-C charging cable
• 18650 battery with 3800mAh capacity (which is impossible)
• 18350 battery with 1100mAh capacity
• Manual (printed on normal copy paper, with very very poor quality printing)

If you buy the V63-F, you will also get a OTG connector. I’m not sure why this is only available with the Floodlight, and not with the Spotlight.

Edit: The manual you receive with the V63-S will be printed on high quality paper! Mine was just printed quickly before sending out.

The flashlight arrived with a 18350 loaded in the flashlight, which measured 3.98V, and therefore ready to use. The 18650 battery was added to the package separately, and measured 4.10V.

In its shortest form, it’s pretty compact for a thrower, and you probably need to get used to its size. It’s the same size as the Manker MC13, Speras M4, and the like.

And in the extended configuration, it’s about the size as any other 18650 flashlight. But I don’t personally enjoy its design when extended. The smooth battery tube is visible, and with the rest of this light, doesn’t look too good, and it doesn’t add any grip.

Handing is pretty easy, extended, where the thumb rests nicely around the switch.

I would probably recommend using this light while camping, or doing some search around the barn/yard/fields. The beam is a little too narrow to use for an EDC.

The tailcap has a small tapped hole where you can attach a magnetic base. This base is optional, but quite nice. It can hold the flashlight in any direction, as far as the base allows. Mine was also strong enough to have the flashlight stay up, when attached to a vertical frame. I heard that some people complained about the the light losing its position, and slowly dropping down.

There is a flat cover with 2 little holes which seems to be there to adjust the smoothness/strength of the inner ball. I don’t really know how to describe this in English.

There is nothing that witholds the flashlight from rolling off a table, and it doesn’t include a pocket clip.

urFLAMP didn’t hide the fact their driver (and likely the flashlights itself) was produced by Speras. How do I know? The driver has Speras printed on it.

That’s actually not a bad things, because Speras flashlights are built very well, and we have reviewed quite a few of them. And some of our reviewers were perlexed receiving a Speras flashlight, so don’t think this is a con. It’s actually a pro, knowing it was made by a well established brand.

This is how many, if not most, flashlight brands start out. And this include other, pretty popular, flashlight brands.

All parts are nicely chamfered, and everything fits together perfectly.  And the anodizing… it’s Type III Hard-Anodized and a very well done satin sheen. It ranks up there with the best of them.

Warranty according to their website:

• The website seems to show a 5 year warranty, however, the details on their warranty policy page, show something different. Here it is:
• The warranty is provided in addition to the rights and remedies granted to you by the seller or granted to you under applicable legislation. Therefore, any remedy (e.g. rectification, claim for damages, right to terminate the contract) granted by urFlamp or by the law applicable remain unaffected e.g., the right to claim lack of conformity within 12 months from the date of purchase.
• The warranty covers all defects compared to the specification of the product in question, that may arise in the product within the below-mentioned warranty period, however, with the exceptions set out below.
• Unless otherwise explicitly stated in documents provided in connection with the purchase, the warranty period is twelve (12) months.

The V63 S uses a TIR optic, and behind it sits a Luminus SFT40 (domeless) LED. 

The bezel is black with some minor ‘teeth’ which I don’t really call aggressive. It is removable, so it can give you access to the internals. And there is yet another indicator that the flashlight was built by Speras, because the MCPCB has Speras printed on it.

The beam is cool white (as expected), and with a pretty tight hotspot. It has a nice, but short, transition to spill.

The light ships with a non-branded 1100 mAh 18350 battery pre-inserted in the light. The battery includes a button-top protection circuit. Inside the package, they also included their 3800mAh rate 18650 battery with the same color and button top.

I measured both batteries, by discharging at 500mA, and with end voltage of 2.85V. I used the SkyRC MC3000 for this.

Here are the numbers:

• 18350: 927 mAh
• 18650: 3515 mAh

It does not accept flat top batteries!

urFlamp says that the built-in USB-C charging charges at 1Amp for the spotlight version, and 2 Amps for the Floodlight version. I measured the battery charging time at 1 hour and 12 minutes with the 18350 battery with the include USB-C charging cable. It has a USB-A port on 1 side, and a USB-C port on the other side of the cable.

The maximum charge current was about 0.96A, but most of the charge time it was charging at a slightly reduced rate. After a couple rounds, I tested the battery capacity with my SkyRC MC3000 analyzer charger, and discharged it at 500mA to get a total capacity of 927 mAh. This is below the advertised 1100 mAh.

I also charged the 18650 battery inside the light, and it took 4 hours and 9 minutes to fully charge. The maximum charge current was measured at 0.96 Amps.

Unfortunately, it doesn’t charge with a USB-C to USB-C cable!

There is a battery indicator inside teh switch, telling the charge status by different colors.

• Green: 70% or more
• Orange: 30-70%
• Red: 10-30%
• Blinking red: below 10%

This is the gear I used for testing:

Gear	Purpose	Link to buy
Hagner E4-X	Measuring beam intensity (throw)	Inquire at Hagner.se
Extech SDL400	Lumens and logging runtimes	Amazon.com, Amazon.co.uk,

Lumen measurements:

How Lumens are Measured: Understanding ANSI FL1 Standards How Lumens are Measured: Understanding ANSI FL1 Standards: The ANSI FL1 standards specify that output in lumens should be measured 30 seconds after turning on, as this is the standardized time for measuring brightness according to the industry standard. This is why we focus on this part in our measurements.

The output measurements in this review are based on my homemade integrating spheres, each equipped with an Extech SDL400 Lux Meter. For consistency and accuracy, a calibration light (Convoy S2+ with 249lm and a Convoy S2+ with 261lm) is measured prior to each set of lumen measurements.
For high-output lights, one of the lux meters uses an ND camera filter to prevent the lux meter to max out. This is either the Kenko PRO1D ND16 up till about 80,000 lumens or Gobe ND32 for anything above.

All of my readings were taken from a fully-charged 18350 and 18650 battery.

The measurements were taken manually at turn on and 30 seconds. The 10 minute numbers are taken from the runtime graph.

Lumens with 18350 battery

Mode	Specified	Measured at turn on	30 sec	10 min
Moon	0.5 lm	0.4 lm	0.4 lm	–
Low	60 lm	61 lm	61 lm	61 lm
Med	220 lm	228 lm	228 lm	225 lm
High	500 lm	521 lm	518 lm	355 lm
Turbo	1500 lm	1868 lm	1638 lm	330 lm

I try to use rounded lumen numbers, except for maybe Low or Moonlight/Firefly modes.

Lumens with 18650 battery

Mode	Specs	at turn on:	30 seconds	10 minutes
Moon	0.5	0.4	0.4	–
Low	60	61	61	61
Med	220	228	228	225
High	500	521	519	499
Turbo	2,000	1,954	1,736	332

Moon, Low, and Medium are performing the same as with the 18350 battery. You can see that a 18650 does help with the higher modes.

Parasitic drain: couldn’t test

urFLAMP V63-S Battery life and runtime

How Runtimes are Measured: Understanding ANSI FL1 Standards About ANSI FL1 runtime standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

The runtime test was done with the 50cm integrating sphere, including the Extech SDL400 data logging Lux Meter.

Here are the runtimes for the V63-S with 18350 batteries, at an ambient temperature of between 24.9 and 28 degrees celsius.

Mode	Specified runtime	Measured runtime (ANSI FL1)	Time till shut off
Moon	220h	–	–
Low	6.4h	5h 57min	5h 57min+
Med	1.6h	1h 36min	1h 36min+
High	1.1h	1h 00 min	1h 00 min+
Turbo	1h	56 min	56 min+

The flashlight kept running for many more hours at sub-lumen level. This could probably continue for 1 or 2 days.

And here for the 18650 batteries

Mode	Specified runtime	Measured runtime (ANSI FL1)	Time till shut off
Moon	760h	–	–
Low	23h	21h 57min	21h 57min+
Med	5.7h	5h 52min	5h 52min+
High	4h	3h 57min	3h 57min+
Turbo	3.9h	3h 51min	3h 51min+

The V63-S doesn’t shut off, and continues running at sublumen level for many, many hours. And I didn’t test Moon mode, which was supposed to do run for 220 hours

urFLAMP V63-S Peak beam intensity and beam distance measurements

About Peak beam intensity: Understanding ANSI FL1 Standards About peak beam intensity The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object). This means that the intensity has decreased so much, it becomes difficult to see darker objects, or objects that don’t reflect light. The columns ‘Meters’ and ‘Yards’ use rounded numbers.

Measurements were taken indoors at 5 meters with a Hagner E4-X Lux Meter.

With 18350 battery

Mode	Specs	Measured Cd	in meters	yards
Low	776	3,425 cd	117 m	128
Med	4,743	13,150 cd	229 m	251
High	15,400	30,225 cd	348 m	380
Turbo	66,000	92,500 cd	608 m	665

Not sure where they got the numbers from, but min performed much better

With 18650 battery

	Specs	Measured Cd	meters	yards
Low	776	3,425	117 m	128
Med	4,743	13,150	229 m	251
High	15,400	30,150	347 m	380
Turbo	110,000 cd	99,000 cd	629 m	688

Low, Medium, and High performed way better than specs. But Turbo was just slightly off. Mine read 107,000 at turn on though. But they should use the 30 seconds measurements.

It’s still a great thrower flashlight for its size!

For the following beamshots, I used a Canon EOS 5D Mk2 with a 50mm lens. Manual settings: ISO1600, 1/4sec, F4, 5000K

The shed is about 65 meters / 71 yards away, and the reflective fence about 200 meters.
