Overkill for recreational divers due to cost and specific use.
Mounting and Attachment:

Handheld lights can be secured to a D-ring for easy access. Wrist-mounted lights are suitable for extended use, leaving hands free. Canister lights are reserved for specific technical diving scenarios.'

Battery Types:
Handheld diving lights may use disposable or rechargeable batteries.
USB rechargeable batteries offer convenience for some models.
Canister lights may have a factory-sealed battery with a longer burn time.

Number of Dive Lights on a Dive:
Always carry at least one dive light as emergency equipment.
For night dives, each diver should have a primary and a backup light.
Non-night dives may require only a backup light for each buddy pair.
Lumens and Brightness:

Lumens measure brightness spread over an area.
Choose the highest lumens you can afford for maximum usefulness. LED technology allows for brighter lights with lower wattage.

Additional Tools: Strobes and Glow Sticks
Strobes, like glow tubes, can be useful for marking buddies or equipment.
Avoid single-use plastic glow sticks; opt for rechargeable alternatives.

Selecting the right underwater diving light involves considering your diving style, preferences, and specific requirements. By understanding the types, mounting options, battery choices, and brightness factors, you can make an informed decision to enhance your underwater experience. Dive safe and dive often!
