Fenix LR35R Rechargeable LED Flashlight – 10,000 Lumens

Fenix LR35R Rechargeable LED Flashlight – 10,000 Lumens

The Fenix LR35R Rechargeable LED Flashlight delivers an impressive 10,000 lumens of maximum output with a beam distance of up to 1,640 feet (500 meters). Designed for search and rescue, industrial inspections, security patrols, outdoor exploration, and emergency response, this powerful handheld searchlight combines exceptional brightness with a compact, easy-to-carry design.

Powered by six Luminus SST40 LEDs and two included 4000mAh rechargeable 21700 lithium-ion batteries, the LR35R provides five brightness levels, a high-intensity strobe mode, and up to 80 hours of runtime. USB-C charging, intelligent temperature regulation, and IP68-rated construction make this high-performance flashlight a dependable lighting solution for demanding professional and recreational applications.

10,000-Lumen High Performance LED Lighting

The Fenix LR35R produces an exceptionally powerful beam using six Luminus SST40 LEDs, each rated for a 50,000-hour lifespan. Its wide 90-degree beam angle provides broad-area illumination while maintaining a maximum beam distance of 500 meters, making it ideal for locating distant objects, illuminating large outdoor areas, and conducting nighttime inspections.

Five selectable brightness levels allow users to adjust light output from 50 to 10,000 lumens, providing the flexibility to conserve battery power during extended operations or maximize visibility when additional illumination is needed.

Six Lighting Modes for Professional Versatility

The LR35R features five continuous white light settings and a dedicated strobe function. A single electronic side switch provides convenient access to the flashlight's lighting modes.

• Turbo: 10,000 lumens for maximum illumination
• High: 3,000 lumens for powerful area lighting
• Medium: 1,200 lumens for general outdoor and professional use
• Low: 450 lumens for extended operation
• Eco: 50 lumens for close-range tasks and maximum battery life
• Strobe: 10,000 lumens for emergency signaling

Dual 4000mAh Rechargeable 21700 Batteries

The Fenix LR35R includes two Fenix ARB-L21-4000P rechargeable lithium-ion power batteries, each with a capacity of 4000mAh. These high-discharge batteries are designed to support the flashlight's maximum 10,000-lumen output.

The removable battery design allows users to carry compatible spare batteries for extended field operations. With a maximum runtime of 80 hours in Eco mode, the LR35R offers excellent flexibility for long-duration outdoor activities, emergency preparedness, and professional work.

USB-C Rechargeable Convenience

The integrated USB Type-C charging port allows both batteries to be recharged directly inside the flashlight. A full recharge takes approximately 3 hours and 30 minutes using a compatible USB wall adapter rated for at least 2 amps.

A built-in battery level indicator displays remaining battery capacity through green and red indicator lights, helping users monitor power levels before and during operation.

• Solid green: 85%–100% battery capacity
• Flashing green: 50%–85% battery capacity
• Solid red: 25%–50% battery capacity
• Flashing red: 1%–25% battery capacity

Intelligent Overheat Protection

High-output flashlights generate heat during extended operation. The LR35R incorporates intelligent temperature regulation that automatically reduces light output when the internal temperature reaches approximately 65°C (149°F), helping manage heat buildup and protect the flashlight's components.

Once the temperature decreases, users can reselect higher brightness settings as needed. This protective feature supports reliable operation during demanding lighting applications.

Electronic Lockout & Intelligent Memory

The electronic lockout function helps prevent accidental activation while the flashlight is stored in a backpack, carrying case, or equipment bag. With the flashlight switched off, a quick double-click of the side switch activates or deactivates the lockout.

An intelligent memory circuit recalls the last selected continuous brightness setting, allowing users to resume their preferred lighting level when the flashlight is switched on again.

Compact Aluminum Construction & IP68 Protection

Despite its powerful output, the Fenix LR35R measures only 5.51 inches long and weighs approximately 8.43 ounces without batteries. Its compact, flattened body provides a comfortable grip and convenient handling during extended use.

The durable aluminum housing features a premium HAIII hard-anodized finish for enhanced resistance to abrasion and everyday wear. IP68-rated dust and water protection, including a 2-meter submersion rating, and 1-meter impact resistance make the LR35R suitable for challenging outdoor and industrial environments.

Important Safety Information

The LR35R produces extremely intense light that can cause eye injury. Never direct the beam into anyone's eyes. Extended operation at higher brightness levels can generate significant heat, so avoid contact with flammable materials and allow the flashlight to cool as needed.

Use compatible protected rechargeable batteries of the same type, capacity, and charge level. Engage the electronic lockout before transporting or storing the flashlight in enclosed spaces.

This flashlight is not represented as intrinsically safe and should not be used in classified hazardous locations requiring approved explosion-protected lighting equipment.
