• Ergonomic military-style grip
• Ideal as a backup light for recreational and technical diving

The Power of Simplicity

The LED ONE was designed with a single goal in mind—to provide the most reliable backup light source in situations where the primary light fails. Its simple design, featuring a minimal amount of electronics, significantly reduces the risk of failure and ensures high operational reliability.

High performance and long runtime

The light uses a powerful 5 W CREE® XPL LED that produces up to 400 lumens of cool white light. The narrow 6° beam provides excellent visibility even in murky water and facilitates signaling underwater.

The LED chip features an exceptional lifespan exceeding 100,000 hours of continuous operation. Power is supplied by three commonly available AA batteries or their rechargeable equivalents.

Proven Reliability

The flashlight body is made of Delrin®—a highly durable engineering thermoplastic with excellent mechanical strength and a long service life. The flashlight head is made of hard-anodized aluminum alloy, which provides high resistance to abrasion, corrosion, and adverse weather conditions.

The front is protected by 6 mm of tempered glass that is resistant to scratches and mechanical damage. A long thread with three O-rings ensures maximum water resistance and reliable protection against water ingress, even when turning the flashlight on and off.

Sturdy and ergonomic design

The LED ONE fits comfortably in your hand, even when wearing thick neoprene gloves. The specially shaped body ensures a secure and firm grip. Thanks to its compact dimensions, the flashlight can be easily stored in a drysuit pocket or jacket pocket and simply attached to the D-ring on a diving harness.

Colored rubber straps allow for easy identification and customization of the flashlight.
