4° Focused Beam & 2500 Lumens

Powered by the Luminus SFT42R LED, the BD42 pushes out 2500 lumens. The precision SMD reflector, paired with an AR-coated 4mm tempered lens, provides a highly concentrated 4° narrow beam.

This intense focus translates to an incredible 618-meter throw, making it perfect for penetrating murky waters and signaling over long distances.

To ensure ultimate safety, the flashlight features an Automatic Lock Function. If turned off for 3 minutes without operation, it locks automatically to prevent accidental activation in your dive bag.

Frequently Asked Questions (FAQ)

Why use a narrow beam underwater?

In water with particles, wide beams can reflect light toward you (backscatter). The BD42's extremely tight 4° beam helps you focus on your target instead, piercing through murky environments.

Is it suitable for deep diving?

Yes, it’s highly rated to 150 meters (IPX-8) and can be used as a primary or reliable backup light for both recreational and deep technical diving.

Will the switch work with gloves?

Absolutely. The stainless steel side switch is designed to provide clear tactile feedback, ensuring easy operation even when wearing thicker dive gloves.

How should I maintain it?

Always rinse the flashlight with fresh water after saltwater use, dry it thoroughly, and regularly check and lubricate the O-rings with silicone grease to maintain the watertight seal.
