The C4 and C8 eLED lights are designed for maximum performance 

underwater.  To do this we take advantage of the fact that LEDs 

are most intense when kept cool.  Two LEDs are attached to a 

heat sink which is in direct contact with the water through the 

front lens.  This patented system cools the LEDs and allows them 

to burn up to 37%  brighter underwater. 

•  Up to 37% brightness increase with water cooled LEDs
•  eLED circuitry insures constant light output for 80% battery life
•  High color temperature LED light travels farther underwater 
•  Full power or battery saving power modes
•  Unique reflector shape combines the beams from 2 LEDs into one
•  Temperature sensing circuit prevents overheating
•  

Polarized battery contacts 

    prevent potentially dangerous reverse battery insertion

•  

Operates with alkaline, Nicad or NiMH C-size batteries

•  Comfortable pistol style grip
•  Switch lock prevents accidental actuation
•  High impact ABS, LEXAN®, polyurethane rubber, 
    and stainless steel construction for durability
•  Made in USA
