Wurkkos TS21

Name: Wurkkos TS21
Brand: Wurkkos
Price: 30 USD
Availability: Discontinued

DiscontinuedWurkkos no longer makes this light; what dealers have left is the last of it. Its current replacement is Wurkkos TS26.

The TS21 was a lower-cost 21700 Anduril light with aux LEDs, high-CRI emitters and strong sustained output, often compared with the pricier D4V2. Wurkkos now points buyers to the TS26 in its place.

What owners report

Wurkkos TS21/4 sources reviewed

A compact 21700 triple that reviewers describe as car-headlight output in a pocket format, with build quality they rate above comparable budget brands. The package is generous — clip, magnetic tailcap, steel bezel, lanyard, USB-C charging and a power bank function — and it lands around $35 to $47.

The dominant complaint is thermal throttling, and it's specific enough to be actionable. The default configuration steps down at 45°C, which causes continuous current cuts and pins sustained output to a few hundred lumens despite the light being capable of over 2,000. Raising the thermal ceiling in the firmware largely fixes it. There is also an odd parasitic drain: the amber status LED pulls around 13mA on its high setting because of an undersized resistor, which will flatten a cell over time if you leave it on.

Consistently praised

Very high output for a compact 21700 body
Build quality reviewers rate above comparable budget brands
Generous kit: clip, magnetic tailcap, steel bezel, lanyard, USB-C
Works as a power bank
Thermal behaviour is configurable, so the main flaw is fixable

Common complaints

Default 45°C step-down pins sustained output to a few hundred lumens
The amber status LED draws about 13mA on high — enough to flatten a cell in storage
Measured output falls well short of the declared figure
The manual leaves out information you need
Firmware is complex for a first enthusiast light

Questions people ask

Why does it dim so quickly on high?: The default thermal ceiling is set to 45°C, which is conservative enough to throttle the light almost immediately. Raising the ceiling in the firmware restores most of the sustained output — this is the single most worthwhile thing to change.
What is the status LED drain about?: An undersized resistor on the USB controller means the amber indicator pulls around 13mA on its high setting. Left on, that will drain the cell over weeks. Set it low or off for storage.
Does it really make 3,500 lumens?: Briefly, and measured output comes in under the declared figure. What matters more is sustained output, which is thermally limited until you adjust the ceiling.
Is it a good first enthusiast light?: The hardware is, but the firmware isn't especially beginner-friendly and the light needs configuring to perform. If you want something that works well out of the box, look at the FC11.
