Nitecore E4K

Skemer's review of the E4K
The E4K is on our top 3 list of best Nitecore EDCs right now. Boasting a new generation 5000mAh, 21700 rechargeable Li-ion Battery, the E4K with its zero fuss, simple operation gives you over 3hrs of 1050 lumens power, but lets you experience the power and brighteness of 4,400 Lumens for 10-15 seconds at a time (30min in total!) thanks to the 4 x CREE XP-L2 LEDs. Some see the short bursts of high lumens as a limitation, we see the opposite. Have you ever wished for a bit more light (or in this case, a lot more!), just to catch a glimps of night life that would otherwise have not been possible but don't have the frequent need for a high-lumens flashlight...and a price tag to go with it?  No flashlight, in such small package will give you high lumens for extended periods - temperature rise being the #1 consideration. We think the E4K is a game changer for 120-150m distances where super bright, flood light is the priority  and where a 1000 lumens otherwise is perfect. With the E4K you buy flood, not spot. We're nothing short of super impressed!
