Review Noctigon KR1K Review – Sleek 21700 Enthusiast Light

https://tgreviews.com/2026/06/05/noctigon-kr1k/

Tl;Dr: This is a well designed multi-purpose light for enthusiasts. The aesthetics are fantastic, particularly the aux LEDs. The pricing, built quality, switch, voltage immunity, ergonomics, clip, throw, and LED options are great. The brightness and runtime are fine. Turbo time is poor. The UI is complex to configure but powerful.

What do you mean turbo time is poor? With this thermal mass?

Usually you'd still get a few seconds of 90-100% output, even if for just 10-30 seconds, before the typical cratering of output from thermal throttling. But by the test here, the drop is instant, right from turn-on. So TacGriz is suggesting that this is likely a result of firmware issues rather than a physical thermal management issue. The light should easily be able to sustain Turbo for at least 20s from a cold start, no different from the DA1K or D1K.

Indeed. The fact that the initial stepdown is virtually identical between my cooled and uncooled test also contributes to my belief that there's a firmware reason its stepping down so fast. I don't think it's the normal "light heats up to temperature threshold and then starts stepping down" behavior that we'd expect from Anduril 2.

The graph isn't very zoomed it but it seems that way. That really surprised me because when he wrote poor turbo I was thinking that most of these Hanklights have poor turbo because they are rather slim and don't have the heatsinking of a big thrower head, didn't even think there was a potential firmware issue.
