Watch: How to Pick the Right Dive Light
This video explains primary vs backup lights, beam angles, battery types, and how to avoid buying the wrong dive light for your type of diving.
Why Every Diver Needs a Light
- Red light disappears at just 20–25 feet underwater.
- Colors fade as depth increases.
- Wrecks and ledges are dark even during the day.
- Lights improve signaling and safety.
Even daytime divers benefit from carrying a light.
Primary vs Backup Light
Primary Light
Your main working light for night dives, caves, wrecks, or photography.
Backup Light
Compact, affordable insurance in case your primary light fails.
Smart divers carry both.
Beam Angle: Spot vs Flood
Spot Beam
- Narrow, concentrated beam
- Great for signaling and pointing things out
- Can “bleach” subjects in photography
Flood Beam
- Wide, even illumination
- Better for photography and videography
- More natural underwater lighting
Battery Types Matter
- AAA / AA batteries – easy to find worldwide
- Rechargeable lithium packs – powerful and efficient
- Exotic batteries – harder to replace while traveling
If you travel internationally, battery availability is important.
LED vs Older Bulbs
Modern LED lights dominate today’s market.
- Brighter output
- Longer battery life
- Multiple brightness settings
- Lighter weight
Older incandescent or halogen lights are heavier and less efficient.
Special Features to Consider
- Red light mode (less disturbance to marine life)
- Strobe or SOS function
- Multiple brightness levels
- Interchangeable heads (spot / flood / UV)
- Canister systems for technical diving
