Sourcing professional LED flashlights requires understanding key performance specifications. This guide covers everything B2B buyers need to evaluate before placing an order.
1. Lumens vs. Candela: Understanding Output
Lumens measure total light output; candela measures beam intensity at a specific point. For tactical and search applications, high candela (beam throw) matters more than raw lumens. Aurora M640DF delivers 1500LM with concentrated beam intensity for maximum throw.
2. IP Ratings Explained
IP68 = dust-tight + submersible beyond 1 metre. IP67 = dust-tight + temporary immersion to 1m. For maritime, diving, or industrial mining applications, IP68 is the minimum requirement. For everyday EDC, IPX4 (splash-resistant) is sufficient.
3. Battery Systems
- 18650/21700 Li-ion: Best for rechargeable high-performance models
- CR123A: Field-replaceable, works in extreme cold, ideal for tactical
- Dual Fuel: Maximum versatility — accepts both formats (see M640DF)
- USB-C built-in: Convenience for EDC and everyday use
4. Beam Optics: TIR vs. Reflector
TIR (Total Internal Reflection) lenses produce a tighter, more defined hotspot — preferred for tactical weapon-lights and long-throw hunting applications. Smooth reflectors deliver a wider flood pattern better suited for area illumination.
5. MOQ and OEM Considerations
Aurora offers OEM from 100 pcs with custom logo, color, and packaging. Sample delivery within 30 days. CE, IP68, ATEX certifications handled in-house.
