The Halcyon name has been synonymous with world class underwater lighting systems for nearly 20 years. We released the Focus lights and then the handheld versions continuing this tradition. The Focus 2.0 has twice the brightness of the Focus 1.0 light.
Halcyon lights are available in corded models (standard cord or E/O cord), as well as a handheld version. Standard corded lights are delivered with a standard 5.2Ah li-ion battery. Divers opting for the E/O cord will receive an industry-standard cord that may be used with the supplied cannister or larger compatible battery systems.
