LED ONE and LED ONE MINI's reliability, it’s a key feature, stems from its simple but robust construction, materials used, build quality and minimal electronics.

Their bodies are machined from a solid piece of Delrin®, an exceptionally rigid and durable construction thermoplastic. The heads are made from hard anodised aluminium, which makes it resistant to abrasion and weather factors.

The LED is protected by 6mm tempered and scratch-resistant glass.

LED ONE and LED ONE MINI's heads are machined with a long thread and are protected with three beefy o-rings.

It guarantees leak tightness for immersion depths up to 200 m and protects the devices from accidental water ingress when switching on and off underwater.
