The L21B + SFT-70 and 6V 8A boost driver is just awesome!

L21B + the SFT70 with the 6V 8A boost driver is pretty awesome! It measured 356,680cd with a throw of 1,194m or 3,917 feet during testing.

The L21B held 100% output for 2m:25s and started to drop as the temperature reached 50.5°C or 123°F.

At 2m:45s the temperature has reached a max temperature of 51.5°C or 124.7°F and output has dropped to 88%.

Right at 3 minutes, the flashlight has dropped to 70% of its max output with temperature dropping to 50.7°C or 123.4°F.

At 5 mins, the flashlight has remained at 70% of its max output with a steady temperature of 122.7°F or 50.4°C.

Next test will be the C8+ with the SFT40 and 3V 8A buck driver :)
