About Princeton Tec, Shockwave II Dive Light

Shockwave II
The Shockwave II allows you to power up from 7.5 watts to 15 watts of power with the flip of a switch. The economical 7.5-watt output mode burns for up to 10 hours and provides plenty of light for most diving conditions. For those pitch black nights, wreck diving and dark crevices, simply flip the switch to the screaming bright 15-watt output mode for 4 hours of burn time.

I use this light for locating lobsters under rocks and or inside crevases. It has a powerful beam that cuts through a lot of the kicked up sand and seaweed. The free tec 40 works as a great backup too.

I only got 2 uses out of this light as the first time i used it to 15 meters then i used it to 18 meters this time as soon as i hit depth water flooded in and the bulb exploded. I have two other friends that had the same light and said it was not any good for them either, it constantly leaks.

Very good reliable light


So far so good


Fast delevery


I love this light


I've been diving for over 30 years, off the Jersey Shore as well as the Caribbean. I've had a bunch of lights. This is the best one I've had. It is compact, easy to use and bright. No cons to this light. 2nd one I've owned. The first one lasted over 13 years.


Hopefully switch gets easier to use


Good, penetrating beam, especially for price. Switch is very still and hopefully will loosen up

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
WILLIAM D  This would be a very good for night dives and would last for many years
Fred B  I've been told that turning the light on out of water will melt/destroy it and it can only be used under water. Is that true?
SCOTTIE S  I've used it out of the water multiple times without issues. I've owned 2 of these lights for over 4 years and they still work perfectly.
Jim W  That is not true. I have used my light for multiple uses out of the water and have not had any issues. My light is coming up on 3 years old and I have used it very many times without any problems in and out of the water.
ROLLIN E  No. I regularly use my underwater lights as flashlights around the house with no problems. They are the best portable light source around. Its a little silly to use them in this manner as they a way more expensive than a non-underwater light. In the "olden days" (like five years ago) the olden halogen bulbs did run pretty hot-hey, the light had to come from somewhere!-but with the newer led lights even that consideration seems to have gone away.
JON P  Not a problem to use it on land. It does get very warm, so I would not use it as a primary land light. Ours does fine out of water.
WILLIAM D  Absolutely not. I use mine to spot varmints in Missouri when I am not on a dive trip. The housing and lamp are still the same that came in the lamp when it was purchased in 2008. It has over 150 dive trips and one hundred hours of hunting trips on it to date. William D Scuba repair tech.
STEPHEN N  There is no warning or restriction in the user guide about out of water use. I have used mine on land (for limited periods) several times with no problems and it still works fine.
DONALD A  That's rediculous
BRIAN W  I have heard the same thing, I believe they can overheat eventually. When I travel I take at least one battery out so they do not come on when packed.
Shopper  Does this light sink or float ?
LeisurePro S  This light is slightly negatively buoyant.
