Review intro:

NEXTORCH is known for their tactically oriented flashlights and law enforcement gear. They supply many products to over 100 countries and agencies around the world. Their “TA” line is the most tactical in the lineup, but he “E” line is a smaller kind of flashlight, and almost feels like it would fit the EDC flashlight category. But that’s not really correct, because it’s not marketed as being an EDC. It’s sold as being a High Power Rechargeable Flashlight. The NEXTORCH E52C is an upgrade from the NEXTORCH E51C we also reviewed, which was again a slight upgrade from the E51. The E52C is advertised at 3,000 lumens, which is about double that of the E51C. They also changed battery type, and moved from 18650 to a 21700 battery. It still has USB-C charging, and with the included battery, you are ready to go.

Package quality.

The E52C is shipped in a white cardstock box with the NEXTORCH logo and photos of the light in front. The back has specifications and some information on charging. The light did ship with a battery, and it came preinstalled in the light, and measured about 3.63V, and with a battery isolator pad stopping parasitic draw while en route. All of the other items came in a plastic zipper bag. All in all, everything was well packaged and, in the box, everything included is:

  • NEXTORCH E52C
  • 21700 Battery 4800mAh (preinstalled)
  • Pocket clip (preinstalled)
  • USB-C cable
  • User Manual
  • Spare O-Rings
  • Lanyard

Flashlight in use

The E52C is made of aluminum, with black silkscreen anodization (Type HAIII) and shallow square-shaped knurling, which is typical for NEXTORCH. This all feel pretty nice in hand, and even though the flashlight doesn’t look very rough, it doesn’t feel slippery at all.

The tailcap houses a forward clicky switch, with 2 ridges on each side, that can be used to attach the included lanyard, or any lanyard in that regard. A half press will activate the light momentarily.

If you don’t like using the included lanyard, you still have the pre-attached pocket clip which fits extremely snug. It’s not easy to remove from the batterytube, and it also help as an anti-roll feature.

Being a forward-clicky switch, it feels a bit like a tactical flashlight, because it can be used in the overhand position. If you carry it in the underhand position, you’d have to use both hands to change modes.

Even though it might sound like an EDC flashlight, it definitely fits more into the tactical group.

NEXTORCH mentions the following tasks: Duty, outdoor, Night patrolling, Industrial, Self defence.

Build Quality and Warranty

The NEXTORCH E52C’s build quality meets my expectations. I have several NEXTORCH flashlights, and although it doesn’t look as good as the NEXTORCH T10L, or NEXTORCH T20L, it’s definitely not a cheap looking flashlight. It’s using durable Type III hard anodized matte black finish, but mine had some minor damage. That’s probably because it went by another reviewers before I received it.

The anodized, threads, with just the right lubrication, are problem-free and can lock the flashlight with a quarter turn. The head of the E52C unscrews but remains attached ,to reach the hidden USB-C port for charging. It’s securely sealed with an o-ring that guarantees effective water resistance.

LED, Lens, Bezel, Beam, and Reflector

While the E51C used a OSRAM P9, the new E52C is using a CREE XHP50, and they name it the XHP50B, which is probably just the XHP50.2. And with a light orange peel reflector, you get the unpopular color shift, which many XHP LEDs suffer from. The beam is very wide, and floody, and there is a hotspot, but the spill is also plenty bright, so the hotspot itself is not too distinct.

The bezel is flat, and protects the AR-coated lens from most kinds of impacts.

The beam was measured with the Sekonic C800 spectrometer, instead of the Opple Light Master 3 I used before. I have another Spectrometer, but it’s stored in a place I couldn’t reach during this review.

Here are the measurements:

  • CCT: 8035K
  • CRI Ra: 71.9
  • duv: -0.0080

This means that the light is very cold, and with a negative duv has a pinkish tint, and in the middle. If you look at the beam itself, you can see the transition to a greenish outer ring.

NEXTORCH E52C comparison

Size compared to a few tactical flashlights, and EDC flashlights

From left to right: NEXTORCH E52C, Olight Warrior 3 (21700), Fenix PD36R (21700), Wurkkos TS21 (21700), Acebeam E70 Mini (18650), Olight Warrior Mini 3 (18650).

The 2 flashlight on the right use a 18650 battery, and the others 21700. You can see that the E52C is very large for being an EDC flashlight, and is likely more of an tactical flashlight.

NEXTORCH E52C Charging and batteries

NEXTORCH moved from a 18650 battery in the E51C to a 21700 in the E52C. This increases the diameter of the battery tube by about 3 millimeters. Not much, but to me, a 21700 flashlight feels just a bit nicer in hand than an 18650.

The included cell has a capacity of 4800mAh, and is labeled NEXTORCH DC20005A. It’s longer than a unprotected 21700 battery. A full charge inside the flashlight took 4 hours and 44 minutes.

With the E52C, you don’t need to invest in a 21700 battery charger, because it has onboard charging via a hidden USB-C port. The USB-C port becomes visible when the head is unscrewed from the body, but the head will never detach. Once unscrewed, simple connect it with a USB-C cable, and you’re ready to go.

The included charging cable is USB-A to USB-C, and the E52C does not charge when using an USB-C to USB-C cable.

Flat top, unprotected batteries won’t fit because they are too short to make contact.

I tested the end Voltage by slightly discharging the battery, and then charging it. I was surprised to see the end voltage being 4.24V. That’s too high!

Performance test

This is the gear I used for testing:

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 NEXTORCH 4800mAh 21700 battery.

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

NEXTORCH E52CSpecifiedTurn on30 sec10 minutes
Low30 lm38 lm38
Med550 lm634 lm630626
High3000 lm3455 lm3258 lm543 lm
High at 3.7V1606 lm1479 lm

I didn’t do a runtime test in Low mode, because it would take 65 hours according to the manual.

I like the fact that even at 3.7V, the E52C can still produce 1600 lumens at turn on, and 1479 after 30 sec. It’s noticeably lower than at full charge (4.2V), but this is something people want to see. I do these tests with a specific battery which is discharged to something between 3.6-3.8V, and check the battery for each test. This time, the battery was exactly at 3.7V

Oh, and all modes measured higher than specified!

NEXTORCH E52C 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.

ModeSpecified runtimeMeasured runtime (ANSI FL1)Time till shut off
Low65h
Med4h 15min4h 33min10h 29min+
High2h 30min3h 19min6h 35min+

The runtime didn’t finish yet when I stopped it. I noticed after the first runtime that the battery went down to 2.51V, which is kind of low in my opinion. You can also see that the output is not regulated.

I would not recommend doing this, so charge the battery, when the output reduces to below 100 lumens.

NEXTORCH E52C 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. The measurements were taken 30 seconds after turn on.

NEXTORCH E52CSpecifiedCandelasMetersYards
Low156 cd1502427
Med2,500 cd2,550101110
High11,025 cd13,825 cd235257

Again, the beam intensity was higher than specified. At turn on, it could easily reach 14,000 cd.

Beamshots

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.

Compared to the following flashlights:

Disclaimer: This flashlight was sent to me for review at no cost by NEXTORCH. I have not been paid to review, nor have I been holding back on problems or defects.

Final Verdict

Pros

  1. Brighter than specified
  2. Package included 21700 battery, and USB cable, so you don’t need to buy a separate charger
  3. Great for tactical use, as it always starts in High mode (3000+ lumens)

Cons

  1. No USB-C to USB-C charging
  2. Beam is very cold, and color shifts at close distance
  3. No regulated output
  4. Low mode is not really low (but not so important for Tactical use)
  5. Discharges to 2.5V and charges to 4.24V

Explanation on star ratings:

1: Avoid: my phone flashlight would be a better choice – 2: Poor: significant defect or issues; almost unusable – 3: Average: some defects or issues; but still usable 4: Good: recommended (minor issues) – 5: Great: highly recommended

3.5 stars: ★★★⋆

While our star rating provides a reliable indicator, we encourage you to read the full review to make an informed decision based on your own needs and preferences.

At first I thought it was marketed as being an EDC flashlight, but nowhere on their sales page do they mention EDC. In fact, NEXTORCH mentions several activities in their marketing material, and EDC is not one of them.

The forward clicky switch, a UI that cycles from High to Low, always starting in High mode, a strobe mode, and large size, make it align more with the Tactical Flashlight category than any other.

If this is what you like, the E52C could still be a good option.
