Why want 10,000 lumens in your palm?

You might ask what such power is for to a mere mortal. The answer is simple: Reserve and Overview. With these flashlights, you don't just see 'the path.' You see the entire meadow, the whole mountainside, or light up the other end of the valley. Whether you are a police officer searching for a suspect, a rescuer searching in rubble, a speleologist in a giant dome, or a cabin owner in the middle of nowhere, these flashlights give you absolute dominion over the darkness.

Fenix LR35R: Compact floodlight for wide surroundings

Let's start with the model that defined the 'flat and short' cannon category. The Fenix LR35R is the ideal choice for those who prefer simplicity and maximum area coverage.

Key Features:

• Wide beam: Thanks to six Luminus SST-40 LEDs, it creates a smooth, wide beam. It's like turning on a giant floodlight in front of you. Ideal for searching a forest or walking in difficult terrain.
• Simple operation: A single side button handles everything. Power on, mode switching, and strobe. No complications.
• Compactness: Batteries are side-by-side, the body is flat and short (only 14 cm). It fits perfectly in the hand and doesn't weigh down your belt.

Verdict: If you want 'a lot of bang' in the smallest possible package and your goal is to light up the largest possible area up to 500 meters, the LR35R is still the winner in price/performance ratio.

Fenix LR35R PRO: Swiss Army Knife for Professionals

The arrival of the PRO version isn't just a cosmetic update. It's a leap into a different league. The Fenix LR35R PRO brings features that experts from armed forces and demanding outdoor enthusiasts have been calling for.

How is the PRO better?

• Beam variability: While the basic version only has a wide flood, the PRO version combines a distance spotlight (500m throw) and a wide floodlight. You can use them separately or together. Need to see far? Turn on the spot. Need to see under your feet? Turn on the flood.
• Rotary switch: A revolution in control. Instead of pressing a button, you smoothly regulate brightness with a rotary ring. This is priceless in gloves or stressful situations.
• Special lights: Includes UV light (for forensic purposes, document checking, or finding blood traces) and red light (for preserving night vision or signaling).
• Powerbank: The USB-C port is bidirectional. In an emergency, you can charge your phone from the flashlight battery (a massive 12,000 mAh total!).

The LR35R PRO offers, in addition to distance and wide reflectors,
a very strong red light and UV light.

Verdict: For tech enthusiasts, police, crime scene investigators, and rescuers, the LR35R PRO is the clear choice. It offers incredible versatility and control that is addictive.

Fenix LR36R: Laser Future (Professionals Only)

If you are looking for the absolute technological pinnacle, meet the Fenix LR36R. Here we reach the limit of the physical possibilities of handheld flashlights. Please note, due to the use of a powerful laser, this flashlight can only be purchased by business entities (B2B).

LEP Technology and OLED Display

The main trump card is the white laser (LEP technology). While ordinary LEDs 'scatter' light, the LEP module in the LR36R sends a concentrated beam up to a distance of 1,260 meters! That's more than a kilometer. Plus, it adds a ring of twelve LEDs to illuminate the immediate surroundings.

• Extreme Throw: Ideal for guarding large compounds, search operations at sea or in the mountains, and tactical operations.
• OLED Display: No more guessing how much energy is left. The display shows the exact battery status, selected mode, and remaining runtime.
• Intelligent Sensor: To prevent burning a pocket or blinding, the flashlight automatically reduces output if you get closer than 6 cm to an obstacle.

The LR36R also features wide floodlight, while the long-distance beam is produced by LEP technology.

Verdict: The LR36R is a tool for specialists. If you need to see a kilometer away and require precise control over battery status, it is the only choice.
