Convoy L21B SST20 Deep Red, 400m Range, 300 Lumens
ANSI FL1 Standard: 300 Lumens
I still need to capture photos and video of this version. See the Hunting Guide for a comparison photo at 100m.
This version of the L21B is using a darker red LED at 660nm wavelength of the red spectrum. Red light starts at 620nm and moves into infrared past 700nm (invisible light). Most other brands out there use 620nm because of the much better range, which is a bit like 850nm IR being brighter than 940nm, both still being very effective, but the 940nm is moreso than 850nm.
