Frequently Asked Questions (FAQ)

Why is a 7-degree beam angle important for a dive flashlight?

A tight 7-degree beam is essential for cutting through water that has high particulate matter (sediment, algae). A wide beam will reflect off these particles, creating a blinding "backscatter". A tight beam penetrates straight through, giving you excellent distance visibility and making it perfect for pointing out marine life.

Can I use the Bludive BD20 as a primary dive light?

Absolutely. For recreational night diving or reef exploration, 1200 lumens is more than sufficient. Because of its reliable build, 150m waterproof rating, and up to 3 hours 40 minutes of runtime on medium, it is widely used as a primary light for recreational divers, and as a highly trusted backup light for technical/cave divers.

How should I maintain the O-rings on my underwater torch?

After every dive, you must rinse your flashlight in fresh water to remove salt crystals. Before your next dive trip, inspect the O-rings (the BD20 includes 3 spare O-rings). If they look dry, apply a very light coating of silicone grease to maintain the 150-meter waterproof seal. Do not over-grease, as this can attract sand.

What does Reverse Polarity Protection mean?

When you are gearing up on a rocking boat in low light, it's easy to accidentally insert a battery upside down. The BD20 features Reverse Polarity Protection, an electronic failsafe that prevents a short circuit and protects the flashlight's internal circuitry if the battery is installed incorrectly.
