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?

Decent light for the price Review by K
Actually- I haven't tried it in the water but wanted to share that I was able to acquire an LED bulb for this light which seems to be as bright (or brighter than) as the halogen bulb which was included. I purchased a PR2-3WHP-9V LED bulb- which is polarity specific, and had to flip the batteries over to get bulb to work. Would think I will get a really long burn time with the LED instead of incandescent or halogen bulbs. Only other issue I had with this light is that the batteries rattle in housing- used couple slips of folded paper to eliminate the rattle. Will update review (if possible) after I get my light into the deep- which may be in awhile. I will also change stars at that time as needed. (Posted on 8/12/2015)
