Ultra-Slim EDC Flashlight

The Nitecore EDC27 UHi is a flat-profile everyday-carry flashlight built around the NiteLab UHi 20 LED. It delivers 3100 lumens of output and throws light up to 333 yards. At only .87 inches thick and 4.30 oz, it slips into a pocket without bulk. The light is intended for anyone who wants high output in a genuinely slim form factor.

USB-C Recharging & Pocket Integration

A built-in 1700mAh cell charges via the integrated USB-C port in 1 hour 15 minutes, removing the need for loose cells or a separate charger. The flat body sits flush in a pocket or bag organiser, freeing space that a cylindrical light would occupy. An OLED screen shows the active mode and remaining runtime. Buyers who need user-swappable batteries or a magnetic tailcap will not find those features here.

Thermal Behaviour & Power Draw

The LED drives 3100 lumens in Turbo; sustained high output will warm the thin body, so the light steps down to protect itself. Lower modes run cool and silent with no fan or moving parts. On the lowest setting the 1700mAh battery provides 55 hours of runtime. There is no external heatsink or active cooling, so extended Turbo use is limited by the chassis mass.

Questions about this item

How long can the EDC27 UHi run at 3100 lumens before heat forces a step-down?

The 3100-lumen Turbo mode is momentary; the light steps down to High after a short burst to manage heat, then runs at lower sustained levels.

How hot or loud does the EDC27 UHi get during all-day carry and use?

The aluminium body warms noticeably on Turbo and High; no fan exists, so it runs silent, but prolonged high output makes the light too hot to hold comfortably.

What cable or charger must I already own to recharge the built-in 1700 mAh cell?

A USB-C cable and any 5 V USB power source — computer port, phone charger or power bank — are all that is required.
