The 400 Lumens Challenge (Part 1): 3 KR1 Flavors Face Off!

Who doesn’t love a good flashlight challenge? We’ve seen it all before:

I’m all in for this kind of fun.

This time, I wanted to put my own Anduril lights through a more real-world test. For my EDC flashlights, I usually keep my memorized manual level right around 400 lumens. This is my all-around preferred level. Anduril UI is giving me the chance to find and set this level. If I find another non-Anduril light pushing 400 lumens at any level, I will test it here. So, the idea was simple:

  • Pick a common level.
  • Compare different configurations.
  • See what really happens.

*sorry I cannot test only one parameter at a time (ex CCT) since I “only” have ~30 flashlights.

For round one, the spotlight is on three Noctigon KR1s, each hosting a different LED but all running the same 9A linear driver. Ceiling T° is set to 60°C. Here are today’s contenders:

Were the results what you expected?

Next up: a FireflyLite X4Q Comet (FFL351A @ 3700 K) using the LumeX1 driver.

What’s your guess? Will it sip power more efficiently than the KR1s, or fall behind because of the lower CCT ?

For consistency, I’ll keep using the VapCell N40 + adaptor in all my 21700 lights.

Let the speculations begin!
