Wurkkos K1 Review: 3-in-1 18650 EDC (Spot, Flood, Ambient)

Short version: the K1 is one pocket flashlight with three lights built in: a spotlight that reaches far, a wide floodlight that shows true colors, and a lantern mode that glows all around. It runs on a swappable 18650 rechargeable battery and charges by USB-C.

Gift shopping? This light is the ~$50 pick in our Flashlight Gifts 2026 by Budget guide.
Wurkkos’s own store showed $52.99 when we checked on October 5, 2026. On Amazon, confirm the listing says K1, not the HD01, HD02, or HD10.
First look based on manufacturer specs. No hands-on sample yet. Every number is linked.
If you grew up with a Maglite 2D in the glove box, “EDC” in 2026 is a different sport: USB-C, a cell you can swap, and — on this one — three beams in one short 18650 host. The Wurkkos K1 is a new 3-in-1: a long-range spotlight, a high-CRI flood, and a 360° ambient lantern with white plus color. It is not a $22 pocket tube. It is not a 21700 work brick. It is the middle of those two jobs, on a replaceable 18650.
Wurkkos put the product page live on September 1, 2026 as a new release. SKU on that page: K1-SFT42R-SG-6K-2. Store copy still prints 2,000 lumens / 400 m on the spotlight. The official user manual’s Table 1 is the chart this review shops: 1,850 lumens turbo, 39,006 cd / 395 m. This is a spec-based first look, not a hands-on test. I have not had one on the desk. What follows is what Wurkkos claims, who it is for, and the catches that actually matter. (Sources: Wurkkos K1 product page; Wurkkos K1 user manual, Table 1 and Table 2.)
What it is
The K1 is a compact 18650 EDC with a Hall-effect switch that flips between three channels: spotlight, floodlight, and “versatile ambient light.” A touch button runs brightness. Twist the head to expose USB-C. Pocket clip in the manual’s overview. In the box, Wurkkos lists the light, a lanyard, O-rings, a Type-C cable, and the manual. (Sources: Wurkkos K1 product page; K1 user manual, “In the box” and Figure 1.)
Store bullets, all from the product page:
- Spotlight: 2,000 lm, 400 m (store). Manual Table 1: 1,850 lm turbo, 39,006 cd, 395 m.
- Flood: 600 lm, 4000K, CRI>90, stepless dimming on the store graphics.
- Ambient: up to 50 lm of 4000K high-CRI white, plus colorful 360° modes.
- Replaceable 18650, USB-C charging.
That is the whole product. No UV. No green laser. No Anduril. No 21700. If you wanted the garage-and-weekend five-source brick, that is the HD02 PRO. If you wanted a simple high-CRI 18650 tube for about $22, that is the FC11C. The K1 is the 18650 that tries to be a thrower, a work flood, and a camp lantern without becoming a coat-pocket tool light. Pocket context: Best EDC Flashlights.
Do not buy a different Wurkkos “K” or “HD” by accident. The HD01 PRO is a flat EDC with UV and a green beam. The HD10 is a 14500 right-angle. The HD02 / HD02 PRO are 21700 work lights. For this review, the listing has to say K1.

Treat these as manufacturer claims, not independent ANSI measurements from this site. Turbo on a compact 18650 almost always steps down. Shop the mid modes. Lumens vs candela: Lumens Explained.

39,006 cd is a real throw number, not a flood. √(39,006 / 0.25) ≈ 395 m, so the manual’s candela and throw lines match. The store’s 400 m is the rounded marketing line. Shop 395 m / 39,006 cd from Table 1, not the 2,000-lumen box. (Source: Wurkkos K1 user manual, Table 1; method as on Lumens Explained.)
Wurkkos Table 1 — spotlight
From the official K1 user manual. The turbo runtime line includes the stepdowns. It is not 1,850 lumens for two hours.
| Mode | Output | Runtime |
|---|---|---|
| Turbo | 1,850 ~ 900 ~ 500 lm | 1 min + 5 min + 1 h 55 min |
| High | 900 ~ 500 lm | 10 min + 1 h 53 min |
| Medium | 350 lm | 3 h 24 min |
| Low | 100 lm | 11 h 12 min |
| Eco | 10 lm | 100 h |
| Moonlight | 1.5 lm | 250 h |
| SOS | 900 lm | — |
| Strobe / Beacon | 1,850 lm | — |
Peak intensity / throw on that same table: 39,006 cd / 395 m. The useful all-evening spotlight on this chart is Medium (350 lm / 3 h 24 min) and Low (100 lm / 11 h 12 min). Eco is 10 lumens for 100 hours — a marker, not a trail beam. Moonlight is 1.5 lm / 250 h. (Source: Wurkkos K1 user manual, Table 1.)
Wurkkos Table 1 — flood and ambient
| Channel | Mode | Output | Runtime |
|---|---|---|---|
| Flood | Max | 600 ~ 310 lm | 3 min + 2 h 35 min |
| Flood | Min | 2 lm | 140 h |
| Flood | Strobe / SOS / Beacon | 600 lm | — |

| Ambient white | Min | 0.5 lm | 150 h |
| Ambient RGB | Moonlight | (not printed) | 13 h 30 min |
| Ambient RGB | Min | (not printed) | 27 h |
Flood max is a three-minute burst, then 310 lumens. Stepless dimming lives on the flood channel (and on ambient white) in the manual’s UI notes — hold the touch button. (Source: Wurkkos K1 user manual, Table 1 and English UI section.)

144 g with the cell is heavier than the FC11C’s ~110 g with cell, on a shorter 106 mm host that is 38 mm tall. That extra height is the flood head and the ambient body, not a Maglite-class club. Cell context: 18650 vs 21700 vs AA. USB-C + a removable 18650 is the default on Best Rechargeable Flashlights.
After power-on, the ambient light shows battery for five seconds: solid green 75–100%, flashing green 50–75%, solid red 25–50%, flashing red 1–25%. While charging: solid red in progress, solid green full. The manual also lists low-battery step-down, low-voltage cutoff, and thermal step-down. (Source: Wurkkos K1 user manual, English section.)
Hall-effect switch plus a touch button
This is not Anduril, and it is not the FC11C’s one-button four-mode UI. Wurkkos’s own graphic: Hall-effect switch between spotlight, floodlight, and RGB/ambient; touch button for the rest. From the English manual:
- Hall-effect switch: Spotlight → Floodlight → Versatile Ambient Light.
- From off, four clicks lock (spotlight flashes twice at Eco). Four clicks unlock. Hold in lockout for momentary spotlight moonlight.
- Spotlight / flood, from off: one click to the memorized level. Triple-click strobe; double-click cycles strobe / SOS / beacon.
- Spotlight: double-click turbo (then turbo / moonlight). Hold from off for moonlight. Hold while on to cycle Eco / Low / Medium / High.
- Flood: double-click max (then max / min). Hold from off for min. Hold while on for stepless dimming.
- Ambient: one click from off for memorized white; hold for memorized RGB color; double-click for dynamic RGB. White gets stepless dimming; RGB hold changes color.
Wurkkos’s product graphic titles the driver story “Constant Current Boost, No Brightness Fade.” That is their copy, not a measurement from this site. The UI is the point and the ceiling: you get three channels without a wiki if you remember the Hall switch. You do not get Anduril. Four-click lockout is the pocket-safety line; the manual is blunt about using it in a bag. (Sources: Wurkkos K1 user manual, English UI; Wurkkos K1 product graphic “Simplified Switch. Full Control”.)
Who it is for
Buy this if you want:
- One current 18650 that does throw, close-up flood, and a lantern without jumping to a 21700 work brick
- A spotlight with a printed 39,006 cd / 395 m line — that is Maglite-class reach on paper, on a 144 g host
- A 4000K CRI>90 flood for work and camp chores, plus 50 lm of 360° white for a tent or bedside
- A replaceable 18650 and USB-C in the body (twist the head), which is the rechargeable story on Best Rechargeable Flashlights
- IPX8 and a 1.5 m drop claim, at a pre-order price under $53
Skip it if you want:
- A $22 one-emitter pocket tube with a clip and a magnet — that is the FC11C
- UV, red, a green beam, and dual-axis wings — that is the HD02 PRO
- A 10 g keychain marker — that is the Wuben E2 Pulse
- Gas-station AA backup. This light is 18650 only. See 18650 vs 21700 vs AA
- Anduril, or a UI you can explain in one sentence. The Hall switch plus click patterns is more homework than the FC11C
- Proven numbers from this site before you spend money. We have not measured one
At $52.99 pre-order it is a mid-price 18650, not an impulse tube and not Acebeam money. The audience is someone who wanted throw and a flood in one pocket light and will live with a 38 mm-tall host. Buying basics: How to Choose a Flashlight. Wider 2026 map: Best Flashlights 2026.
Comparison
Versus the Wurkkos FC11C (the cheap 18650 tube)
The FC11C is the honest cheaper alternative on this site. One Nichia 519A, orange-peel flood-leaning beam, buck driver, clip, magnet, USB-C in the body, four-click lockout, about $22. Turbo 1,200 lm / 155 m / 6,008 cd, and that turbo is a 90-second burst. ~110 g with cell, 116 mm × 24 mm. Simple UI. (Source: FC11C review; Wurkkos FC11C.)
Read the candela line next to the K1. The FC11C claims 6,008 cd / 155 m on 1,200 lumens. The K1 manual claims 39,006 cd / 395 m on 1,850 lumens. That is the whole pitch: the K1 is the thrower. You pay about 2.5× the money, you carry 38 mm of height instead of a 24 mm tube, and you add a flood channel and a lantern. If you wanted high-CRI light in jeans for $22, that is the FC11C. If you wanted 400-meter-class reach plus a work flood in the same 18650, that is the K1. They are not the same light at two prices.
Versus the Wurkkos HD02 PRO (the 21700 5-in-1)
The HD02 PRO is the other current Wurkkos hybrid, and it is a different cell and a different job. 21700, 3,200 lm / 330 m / 27,175 cd spotlight, dual-axis high-CRI wings, 660 nm red, 365 nm UV, 520 nm green beam, launch $89.99. Coat-pocket work light. (Source: HD02 PRO review; Wurkkos HD02 PRO.)
The K1’s 39,006 cd / 395 m actually claims more reach than the HD02 PRO’s 27,175 cd / 330 m, on an 18650, at a lower price. What you give up is the wings, UV, red, green beam, and the fatter 21700 runtime. If the job is “one light for the garage, the inspection, and the trail,” that is still the HD02 PRO. If the job is “throw plus flood plus a lantern that lives closer to a pocket,” that is the K1. Do not buy the PRO thinking it is a K1, and do not expect the K1 to do UV.
Versus a Maglite 2D (the 90s icon)
Maglite’s current ML300LX 2D LED is rated 487 lumens, 323 m, 26,139 cd, 9.125 in / 231.8 mm, 20 oz / 566 g with batteries, IPX4, Eco 260 hours, alkaline D cells, not USB-C. (Source: Maglite, Specifications — ML300LX 2D; as cited on Lumens Explained.)
On paper the K1 throws farther: 1,850 lm / 395 m / 39,006 cd in a 106 mm, 144 g 18650. The Mag still wins if you want stores everywhere, D-cells in a hurricane, and a light you can use as a hammer. It is a glove-box club. The K1 wins if you want USB-C, a spare 18650, and a flood plus lantern in the same host. Different jobs. The Mag lives on the camping page, not next to this tube.
Honest weaknesses
- Store 2,000 lm / 400 m vs manual 1,850 lm / 395 m. Shop Table 1. The 2,000 / 400 line is the product-page screenshot. Candela 39,006 and 395 m are internally consistent; 400 m is rounded.
- Turbo is a one-minute burst by design. 1,850 ~ 900 ~ 500 lm, 1 min + 5 min + 1 h 55 min. High is also a burst (10 minutes at 900, then 500). Shop Medium and Low. Flood max is three minutes at 600, then 310.
- 18650 only. No AA, no 14500 dual-fuel. If the grid is gone and you only have grocery-store cells, this light is a paperweight unless you packed a spare 18650 or a power bank.
- UI is a Hall switch plus a click chart. Fine if you wanted three channels. A ceiling if you wanted the FC11C’s one-button four modes. Four-click lockout is mandatory in a pocket — the manual says so.
- 38 mm tall, 144 g with cell. Shorter than the FC11C, thicker. It will not disappear in jeans the way a 24 mm tube does. 144 g is still a fraction of a Maglite 2D, not a coat-pocket 21700 brick.
- Brand-new as of September 1, 2026. Pre-order window, zero sold on the store tile this morning, no independent review from this site. Amazon may not have a clean listing yet. Confirm any marketplace tile says K1.
- RGB lumen numbers are missing on the moonlight / min rows of Table 1. Do not pretend this site knows how bright the party mode is.
Caveats for a first look
- This site has not had a K1 on the desk. Every lumen, candela, and runtime figure above is Wurkkos’s, except where a named Maglite or other Wurkkos sheet is cited as theirs.
- Two peak numbers. Listings that say “2,000 lumens / 400 m” without the manual table are selling the store bullets. Table 1 tops out at 1,850 lm / 395 m / 39,006 cd.
- IPX8 is a dunk rating on Wurkkos’s table, not a dive light. The 1.5 m drop is the printed impact line, not a torture test from us.
- Price and listing were checked on wurkkos.com on September 1, 2026. The page was in a Sep. 1–7 pre-order at $52.99. Schema on that page also read out of stock at fetch time — confirm cart status before you count on a ship date. Amazon is a search — confirm the listing says K1.
Bottom line
The K1 is Wurkkos’s current 3-in-1 18650 as of September 1, 2026: a spotlight the manual rates 1,850 lm / 39,006 cd / 395 m, a 600 lm 4000K CRI>90 flood, and a 50 lm 360° ambient lantern, USB-C, IPX8, 106 × 30 × 38 mm, 144 g with a 3,000 mAh cell. Turbo is a one-minute screenshot. The useful light is spotlight Medium/Low and the flood after the three-minute burst. It is not a Maglite, not an FC11C, and not the HD02 PRO.
If this site’s Maglite posts are “how we got here,” this is the 2026 chapter of “what a pocket light looks like when the maker puts throw, flood, and a lantern on one 18650”: shop the candela line, pack a spare cell, do not shop the 2,000-lumen store bullet.
Next step for a proper review: get a sample, measure 30-second lumens and candela on the spotlight, time the one-minute turbo stepdown, try the flood on a real fender, and see whether the Hall switch is a feature or a fiddle in a pocket.
