The 'Beacon' Field Flashlight | Fenix E28R V2.0 1700-Lumen Rechargeable Compact Field Instrument

The Experience

1700 lumens. 895 feet of beam reach. A warning pulse light that signals your position in low visibility conditions. A magnetic tail that turns any metal surface into a hands-free mount. A two-way clip that carries in either direction. And a dual-battery architecture that runs on a rechargeable 18650 in normal operation — or two CR123A batteries when the field demands it. The Beacon is the Fenix E28R V2.0 — a compact, single-switch high-output field flashlight that fits in a shirt pocket and outperforms most flashlights twice its size. Five output levels from 5-lumen Eco to 1700-lumen Turbo, a 260-hour maximum runtime at the low end, IP68 waterproofing, 1.5-meter drop resistance, and the Fenix Limited Lifetime Warranty behind every unit. This is the flashlight that goes everywhere, does everything, and never gives you a reason to reach for anything else.

Scientific Engineering

• 1700-Lumen Turbo Output: The Luminus SST40 LED delivers a maximum 1700 lumens with a beam reaching 895 feet — a remarkable output-to-size ratio that puts The Beacon in a performance category well above its physical footprint, illuminating terrain, property boundaries, and field environments at distances that most compact flashlights simply cannot reach.
• Five-Level Output Architecture:
  • Turbo: 1,700 lumens / 2.1 hrs / 895 ft.
  • High: 600 lumens / 2.8 hrs / 538 ft.
  • Medium: 250 lumens / 17.25 hrs / 262 ft.
  • Low: 50 lumens / 36.8 hrs / 148 ft.
  • Eco: 5 lumens / 260 hrs / 49 ft.
• Strobe Mode: 1,700-lumen strobe for emergency signaling — accessible via the single side switch for immediate activation when needed.
• Warning Pulse Light: A 1-lumen breathing pulse light activates to signal position in low-visibility conditions — a passive, low-drain indicator that marks the instrument's location without depleting the primary battery. Essential for nocturnal field work where knowing where you set your light down matters.
• Single-Switch Operation with Intelligent Memory: One side switch controls all output levels with a battery level indicator that glows for 3 seconds on activation — green for 100-85%, flashing green for 85-50%, red for 50-25%, flashing red for 25-1%. The intelligent memory circuit recalls the last selected output on every subsequent activation.
• Dual-Battery Architecture: Primary operation on the included Fenix ARB-L18-3400 3400mAh 18650 rechargeable battery via USB-C charging. Emergency backup operation on two standard CR123A non-rechargeable batteries — a meaningful field reliability advantage when recharging isn't possible. Note: CR123A batteries cannot be recharged via the USB-C port.
• USB-C Rapid Recharge: Full recharge from depleted in approximately 3 hours via the integrated USB-C port. No battery removal required.
• Two-Way Body Clip: The reversible body clip mounts in either direction — tip-up or tip-down — accommodating any carry preference or pocket configuration without additional hardware.
• Magnetic Tail Mount: A strong integrated magnet in the tail cap provides instant hands-free attachment to any ferrous metal surface — vehicle panels, equipment frames, gate hardware, and tool surfaces — for stationary field station lighting at any angle.
• Tail Stand Capability: The flat tail cap allows The Beacon to stand vertically on any flat surface, directing the beam upward as a diffused area light when a hands-free stationary configuration is needed without a metal mounting surface.
• Electronic Lockout: Press and hold the side switch for 3 seconds to engage lockout — preventing accidental activation during storage, transport, or pocket carry.
• Intelligent Thermal Management: Automatic step-down activates when internal temperature reaches threshold — protecting the LED array and battery during sustained high-output operation without operator intervention.
• IP68 Waterproof & Dustproof: Submersible to 6.6 feet for 30 minutes — the highest waterproof rating in its class, providing complete protection against rain, submersion, and active field conditions.
• 1.5-Meter Drop Resistance: Drop-tested from 1.5 meters onto hard surfaces — the durability standard for a field instrument expected to perform in uncontrolled environments.
• Luminus SST40 LED — 50,000-Hour Lifespan: The high-performance cool white LED is rated to 50,000 hours of operational lifespan with antireflective glass lens coating for maximum light transmission efficiency.

Boutique & Conservation Values

• Dual-Battery Field Reliability: The ability to run on either a rechargeable 18650 or two standard CR123A batteries eliminates the single point of failure that makes USB-only flashlights a liability in extended field operations. When the rechargeable battery is depleted and a power source isn't available, The Beacon keeps working.
• Warning Light for Nocturnal Operations: The 1-lumen pulse warning light is a meaningful feature for the nocturnal wildlife observer or estate steward operating after dark — a passive position marker that doesn't compromise night vision and doesn't drain primary battery reserves.
• Permanent Kit Status: The combination of compact form, dual carry options, magnetic tail, dual-battery architecture, and 260-hour maximum runtime makes The Beacon the field flashlight that earns permanent kit status — not the one that gets left behind because it's too large, too single-purpose, or too battery-dependent.
• Fenix Limited Lifetime Warranty: Every Beacon is backed by Fenix's Limited Lifetime Warranty — 15-day replacement for manufacturing defects, 5-year free repair for normal use issues, and lifetime limited warranty coverage beyond that.
