Nitecore EDC27 UHi Review: Ultra-Slim Power Meets Tactical Speed
Overview
The Nitecore EDC27 UHi is the successor to the widely loved EDC27, now equipped with dual UHi 20 MAX LEDs. Delivering 3,100 lumens in an ultra-flat frame, this flashlight is built for users who demand powerful output in a minimal silhouette. It's pocketable, tactical, and surprisingly intelligent.
Why It Stands Out
The EDC27 UHi refines what the original EDC27 started. With upgraded LEDs, more efficient beam control, and real-time readouts on an integrated OLED display, this version takes the slim EDC category to new heights. For those who want the flattest form factor without compromising performance, this is it.
Design & Build
Measuring just 137.8mm long and 14.2mm thick, the EDC27 UHi slides into your jeans or tactical pouch with ease. It’s crafted from stainless steel and reinforced with carbon fiber for enhanced durability. The titanium-coated clip supports deep carry and fast retrieval.
Optics & Output
Equipped with two UHi 20 MAX LEDs, this light produces a 3,100-lumen turbo mode and a beam that reaches up to 310 meters. The beam pattern is a tight central hotspot with functional spill, making it ideal for mid- to long-range use. A tactical mode allows rapid burst output, while general modes provide everyday flexibility.
Battery & Runtime
The integrated 1700mAh lithium-ion battery charges via USB-C and can run up to 55 hours in ultralow mode. The OLED screen shows real-time battery status and brightness level, which is a huge upgrade over blind cycling through modes.
Thermal & Safety
Built-in ATR (Advanced Temperature Regulation) adjusts output dynamically based on internal temperature. The Rapid Lock™ system physically prevents accidental activation, a necessity in such a compact high-output light.
Field Use & Practicality
From mechanics to first responders, this light fits those who need quick access and reliable performance. The slim profile is deceptive—it’s tough, waterproof (IP54), and fast to deploy thanks to the dual-stage trigger button and lockout switch.
Verdict
The Nitecore EDC27 UHi is the most refined ultra-slim flashlight on the market. Whether you're a minimalist EDC enthusiast or a professional needing a secondary tactical option, this tool delivers. There’s no fluff—just flat-out performance.
"When low-profile doesn’t mean low-performance — EDC27 UHi sets the new slim standard."
Frequently Asked Questions
Can I pocket-carry this daily?
Yes. Its ultra-slim design and deep-carry clip make it one of the most pocketable 3,000-lumen flashlights available.
Is the display useful or just a gimmick?
Very useful. The OLED shows exact brightness, runtime, and battery levels—giving users immediate control over output.
Does it get hot quickly?
In Turbo mode, yes—but it self-regulates and cools quickly due to the flat body’s heat dispersion and built-in ATR tech.
