Halcyon Proteus 3 Fixed focus

For divers who want a traditional sealed lead acid battery design, Halcyon now offers both the Proteus 3 and Proteus 6 canister lights. Designed as our entry level 10w HID system, the Proteus 3 provides a generous two hour burn time with a slim form factor.

 Halcyon now offers two 10w HID light heads for the Proteus lights: a compact fixed-beam head utilizing a MR-11 style bulb and the focusable 10w head that comes standard on the Explorer 4.5 light. The Proteus 6 lights are available with multiple lamp configurations, but with the 18w HID it burns for two hours and is our most affordable high performance cave and wreck system. Proteus canisters are milled to exacting tolerances from a new high performance plastic that allows us to eliminate the bulkhead on the battery pack.
