Lumens

Lumens measure the total amount of visible light a flashlight emits—the higher the lumen rating, the brighter the beam. Use the menu above to filter by lumen output and find the perfect balance of brightness, runtime and size for your needs, whether you want a subtle glow for reading maps or a blinding beam for search and rescue.

How to Choose the Right Lumen Range

  • 0–500 lm

    • Close Tasks & EDC: Perfect for map reading, tent setup, indoor chores and everyday carry.

    • Extended Runtime: Low power draw yields runtimes of 10+ hours on low modes.

    • Night-Vision Friendly: Gentle glow preserves your night-vision and minimises glare.

  • 500–1,000 lm

    • Trail & Commute: Bright enough for hiking trails, urban commuting and garage work.

    • Balanced Performance: Runtimes of 4–8 hours on medium settings.

    • Versatile Beam: Good mix of flood for nearby tasks and moderate throw.

  • 1,000–2,000 lm

    • Tactical & Outdoor: Ideal for security patrols, search-and-rescue training and serious camping trips.

    • Medium-Range Visibility: Spot distances of 100–200 m.

    • Turbo Bursts: Short-duration boost for signalling or disorientation.

  • 2,000–5,000 lm

    • Professional Use: Suited to industrial inspections, night-time construction and large-area flood lighting.

    • Strong Throw & Flood: Beam distances up to 300 m with broad coverage.

    • Thermal Considerations: Often features heat-management step-down or built-in cooldown timers.

  • 5,000–10,000 lm

    • Search & Rescue: Penetrates fog and rain for SAR operations and perimeter sweeps.

    • High Heat Load: Designed for brief high-output runs; look for powerful heat-sinks.

    • Specialty Spotlights: Long-throw spot modes reaching 400–600 m.

  • 10,000–20,000 lm

    • Extreme Throw: Dedicated searchlights and LEP strobes used by professional teams.

    • Beam Reach: Distances exceeding 600 m, cutting through haze and darkness.

    • Mission-Critical: Rapid-deploy lighting for large-scale search, rescue or tactical scenarios.

  • 20,000–30,000 lm

    • Industrial-Scale Lighting: Flood/spot hybrids for construction sites, open-pit mining or film production.

    • Dual-Mode Output: Switch between broad-area illumination and focused long-throw beams.

    • Integrated Cooling: Active fans or large-mass heatsinks to manage continuous operation.

  • 30,000–200,000 lm

    • Specialized Searchlights: Vehicle-mounted and remote-controlled light towers for emergencies, marine rescue or large-venue events.

    • Ultra-Long Throw & Coverage: Beam distances beyond 1 km and flood coverage for vast areas.

    • Professional Grade: Requires robust power sources and dedicated thermal management systems.

Balancing Brightness, Runtime & Size

  • Battery Trade-Off: Higher lumens drain cells faster—choose output based on mission length.

  • Thermal Management: Very high outputs demand quality heat dissipation or step-down features to protect LEDs.

  • Beam Profile: Flood beams light wide areas; spot beams concentrate light for distance. Adjustable-focus models let you dial between both.

Maintenance & Best Practices

  1. Keep Optics Clean: Wipe lenses and reflectors with a soft, dry cloth to maintain maximum output.

  2. Inspect Seals & Threads: Check O-rings and focusing mechanisms; re-lubricate annually to preserve waterproofing.

  3. Charge & Store Properly: Recharge after each use, avoid deep discharge and store torches at ~50 % charge in a cool, dry place.

  4. Test Before Critical Use: Verify mode cycling and beam alignment before any vital or remote operation.
