Kinds of Dive Lights include the following:

LED dive lights

• LED dive lights use Light Emitting Diode (LED) technology to produce high-intensity light that reaches longer underwater distances than ordinary bulbs.
• They have as much as 300 times more bulb life than standard light bulbs.
• They run on several alkaline batteries.
• They can be used until around 180 feet.

Rechargeable dive lights

• Rechargeable dive lights usually run on several reusable nickel cadmium (NiCd) batteries.
• Their burn time is approximately one-and-a-half hours.
• They use bright halogen bulbs that provide illumination until 1,000 feet.
• Some models can be used with alkaline batteries if the NiCd batteries have run out.

Mini dive lights

• Mini-dive lights are ideal for looking at marine life, tank gauges, and boat wreckages up-close.
• They resemble penlight flashlights.
• They use xenon lamps.
• They run on several alkaline batteries.
• They can be used until around 500 feet.

Large dive lights

• Large dive lights use powerful xenon lamps that can burn up to 10 hours straight.
• They usually run on several disposable alkaline batteries.

Casing: Choose a dive light made of durable polycarbonate plastic. This material does not crack easily even when several hundred feet underwater. It is also resistant to corrosion and rust.

Accessories: Look for a dive light with a wrist strap or rubber lanyard. This allows you to hang your light on your arm to free your hands for other purposes.

Power source: If you are an occasional diver, look for a dive light that runs on disposable batteries. Invest in a powerful rechargeable dive light if you are a regular or professional diver.
