The “Old Faithful” of our dive line, the TEC 400’s classic and rugged design has been a staple in the dive industry for decades. 4 C-Cell batteries power the clean incandescent bulb for up to 8 hours of underwater light. They say “you can’t teach an old dog new tricks,” but with a light as reliable as the TEC 400, why would you want to?
This pattern creates a long, powerful beam of light excellent for illuminating distant areas. The resulting long-throw spotlight is especially well-suited for night hiking and search and rescue.
HALOGEN BULBS work in exactly the same way as traditional incandescent bulbs found in your home with one major difference: they contain halogen gas instead of nitrogen or argon. This difference allows the bulb to burn brighter, more efficiently, and for longer periods of time. The bulb needs to be replaced less frequently since filament life is extended.
