LED ONE's reliability, it's a key feature, stems from its simple but robust construction, materials used, build quality and minimal electronics.
The LED ONE body is machined from a solid piece of Delrin®, an exceptionally rigid and durable construction thermoplastic. The head is 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 head is machined with a long thread and is protected with three beefy o-rings.
It guarantees leak tightness for immersion depths up to 200 m and protects the device from accidental water ingress when switching on and off underwater.
