Shortest

Skilhunt EC200S-Mini UV

18350 white + UV EDC

Shortest body in the report. Adds a 365 nm UV channel rated at 1000 mW and USB-C charging, but it uses one 18350 cell rather than AA/14500.

AA/14500 pick

Skilhunt EC150

Straight EDC, side switch

Shortest dual-fuel AA/14500 light here, with USB-C charging for 14500 cells, magnetic tail, and a high-CRI Nichia 519A option.

Feature-rich

Wurkkos HD10

Right-angle headlamp / EDC

Anduril 2.0 UI, RGB aux LEDs, USB-C charging, selected 14500-battery variant, and a 4000K CRI95+ emitter option.

Baseline

Lumintop Tool AA 3.0

Slim physical baseline

Longer and narrower than the compact comparison lights. Useful as the familiar AA/14500 tail-clicky reference shape.

Side-by-side Specs

Primary specs come from official product pages and manuals. EC200S-Mini UV and KR4 are different battery classes, so size and use-case notes matter as much as output.

Technical Output Tables

Mode tables are manufacturer-published values. Runtime and brightness depend on cell, temperature, thermal step-down behavior, and emitter selection. EC200S-Mini UV output rows focus on official max/beam values because the UV manual table is image/OCR-heavy.

Caveats And Sources

Source notes and unresolved spec gaps

Skilhunt EC200S-Mini UV: official sources list 71.0 mm length, 25.0 mm head diameter, and 42.5 g empty weight. Official body diameter was not found; same-host EC200S Mini reviews measure roughly 22 mm body/tube diameter. The current product selector says Nichia 519A 5000K, while the older/manual output text still references the discontinued 4500K version. The 2100 lm title applies to the CREE cool-white option; Skilhunt also lists SFT25R as 1850 lm in one official area and 1800 lm in another.
Skilhunt EC150: body diameter, separately labeled R9, SFT25R CRI, and L2 runtime were not found in official sources. The manual prints the Nichia line as CRI 9080, but the product page clearly lists the Nichia 519A option as CRI90.
Wurkkos HD10: body diameter and whether the 46 g weight includes the battery are not stated in the official text. The manual lists 1 m impact resistance; one official marketing image reportedly says 1.5 m, so this report uses the manual value.
Lumintop Tool AA: the baseline is Tool AA 3.0 aluminum. Tool AA 2.0 has different LED/output specs. Official CRI is not listed; the Ra about 70-74 value comes from 1Lumen sample measurements, not Lumintop.
Noctigon KR4: included only as an 18650/18350 size reference. LED, CCT, CRI, optic, driver, and output depend on the selected configuration, so the report does not rank it against fixed AA/14500 output tables. Official and independent dimensions agree within rounding.
