Halcyon EOS 4.5 LED dive light
The promise of LED technology that can fully replace HID lighting just took a step forward with Halcyon’s newest Eos primary light. The new Eos capably blends numerous desirable features with a focused light output exceeding the 10-watt HID.
The Eos also reduces battery consumption with an efficient array of dual-intensity LEDs—a quick flip of the switch more than doubles the battery’s run time! A machined aluminum head shields a nearly indestructible LED light array with an expected lifecycle of 20,000 hours. A set of innovative Halcyon features round out the Eos by adding a custom tie point for the Goodman handle and a specially machined rear bolt-snap attachment point.
The Halcyon Eos represents the dawn in a new age of underwater lighting and is a welcome addition to our line of primary lighting.
