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.
