Halcyon's new EOS LED light head
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 umbilical dive torch capably blends numerous desirable features with a focused light output exceeding the 10watt HID.
The EOS also reduces battery consumption with an efficient array of dual intensity LEDs totaling 12 watts; a quick flip of the switch and you more than double the battery’s burn 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 boltsnap 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.
Comparing the 600 lumen Halcyon EOS to the 1000 lumen Hollis LED16:
“The beam of the Halcyon EOS beam was not only wider but also whiter and, and about 50%.”
