The best 18650 city EDC.
Samsung LH351D Nominal CCT: 4000K Color Rendering Index: 90+
User Selectable Levels: 3 main levels (High, Medium and Low). Each main level can be programmed to one of its two sub-levels. The second sub-level of the each main levels can be further programmed to different brightness levels.
Light Output (runtimes) High: H1 828 Lm (PID, ) or H2 533 Lm (PID, )/314 Lm ()/168 Lm () Medium: M1 83 Lm () or M2 37 Lm ()/15.3 Lm ()/5.7 Lm () Low: L1 1.9 Lm () or L2 0.62 Lm ()/0.17 Lm ()/0.05 Lm () Beacon Strobe Mode: 0.2Hz Beacon at Low / 0.2Hz Beacon at H1 / 4Hz Strobe at H1 / 19Hz Strobe at H1
Operating Voltage Range: 2.7V - 6.0V
Battery: One 18650 size (i.e. unprotected, 65.0-65.2 mm long) 3.6-4.35V li-ion rechargeable. Batteries are not included in the package.

Features PID thermal regulated outputs (two highest output levels) Builtin battery protections with continuously monitored temperature, current, and voltage, plus a (2.7V) low voltage cutoff Battery capacity indicator (LED flashes 1-4 times, 4 short clicks to start) Automatic stepping down from High to Medium, and from Medium to Low when battery capacity is low Durable electronic soft-touch switch Smart user interface provides fast and easy access to all brightness levels and beacon-strobes. Precision machined unibody casing from premium grade aluminum bar stocks Proprietary heat sinking design bonds the LED board directly to the unibody aluminum casing Durable natural hard anodized finish (Type III Class I) Sealed and potted LED driver circuitry Tempered optical grade glass Orange peel textured reflector Battery reverse polarity protection Pre-installed pocket clip Waterproof to IPX8 (2 meters, 30 minutes)
Here is how I have my light programmed. I am not a fan of hacking the G6 and G7, to get shortcuts to behave differenly. Mine is set up, so G6 is “low/bedside night light” mode and G7 as “outside” mode.
You can change the mode with 5, 6 or 7 clicks from OFF respectively.
