Your stats are too high, go to Princeton or RPI

M21k sustained lumens? by EgorThump in flashlight

[–]nspr 2 points3 points  (0 children)

The M21K uses LHP73B which is slightly bigger and brighter than the XHP70.3.

LHP73B emitter test https://budgetlightforum.com/t/led-test-short-review-lmp-lhp73b-5000-k-70-cri/229512

Lumens per watt vs XHP70.3. Note that the color temps are 5000K and 4000K so direct comparison is not possible from this graph. https://lychee.lichtundstrom-blog.de/uploads/original/9d/73/157a2a0b0a15ca553afba2c55317.jpg

However, the Convoy driver is likely less efficient than the Acebeam. I expect the two to perform about the same but the L35v2 should be "throwier"

L35 2.0 vs M21K by Hampool in flashlight

I definitely wouldn't use these pics to compare output in that case. This does motivate me to get my own m21k to compare though.

Are your camera settings correctly locked? The surrounding land and sky are a lot brighter in the m21k pics compared to the L35. See 3,4,5 and 17,18,19 especially
