- Reading-Signaling (up to 200 lumens): Very small flashlights (keychain/wrist) mainly for reading instruments (dive computers) or for safety signaling.
- Backup - Spare (200-499 lumens): The classic backup pocket flashlights that a diver always carries in case the primary one goes out.
- Daytime Torches (499-999 lumen): Lenses for recreational use, ideal for illuminating crevices and holes in the rocks during the day or for simple spearfishing.
- Primary Diving Lights (999-1999 lumen): The standard primary flashlight for night scuba diving. It offers the ideal balance of brightness and battery life.
- Photography Requirements (2000-4999 lumens): Powerful flashlights with a wide beam, suitable for demanding dives (e.g., deep dives, murky waters) or as a basic low-budget light for an underwater camera.
- Professional Spotlights (5000+ lumen): Top lighting systems (usually Canister or High-End Video Lights) for technical diving (caves, wrecks) and professional video recording.
- from 11 to 30 hours: It determines the beam range: a narrow angle (up to 15°) concentrates the light to “pierce” murky water, while a wide angle (60°–120°) spreads it evenly, ideal for night dives and underwater videography.
- LED: It offers top brightness, huge battery life, and complete shock resistance, making it the most reliable and economical choice for safe lighting on every dive.
