"This compact eight C-cell torch packs a lot of punch. It projects a large hot spot, offers bright peripheral illumination and delivers a wide beam with an excellent, mottle-free light pattern. It's made with a dual-filament multi-outpost bulb that allows you to power up from a light-up-the-night 7.5 watts to a terrify-the-fish 15 watts when you need it." -Scuba Diving Magazine

Reviewer: John Neff  -  View all my reviews
Good product, but the three position switch is a bit difficult to use, especially with gloves keeping it from being a great product. The light beam (on high) is bright, but fairly broad, certainly not a spot light, which makes the rated brightness a bit mis-leading. Has a long battery life. All in all a good product well worth the money, but a better switch would be a great improvement.

Rating: Great Light
Reviewer: Bernie Loewen  -  View all my reviews
I am extremely pleased with the intensity of this light. I dive a local lake that has poor visibility at best, and this light gives just what is needed to be comfortable in the dive and allow me to find my way around. A great light at a really great price.

Rating: Fantastic
Reviewer: Sean McSharry
Took this on a night dive in Cozumel. This thing throws out a massive amount of light. One thing that is important to note is that this is more of a flood light than a spot. Used with my Princeton Torrent LED which is a great combo as the LED is much more focused.

Rating: Well Worth It!
Reviewer: Ryan R.
For as cheap as the light was (around $50 cheaper than other similar models), the light has worked WONDERFULLY! Great spot beam for keeping track of my buddy on night dives, and I love the low and hi options - the hi brings out every color imaginable, even in the darkest little crevices.

Rating: Did the job
Reviewer: kasey s.
I needed a light for snorkeling in 3-6 feet of water, looking for spiny lobster in Southern CA. This light did the job. This light, on the "high" setting, gave me an excellent view of everything within 5 feet. Visibility can be somewhat poor in the location I was in, so 5-6 feet was about the limit of any light. I like its smaller size for getting into all the tight places while searching for lobster. I would definitely recommend this light to a friend. Good light at a good price.

Questions and Answers for Princeton Tec Shockwave II Light:

  • A.:

    We have a Princeton Tec Tech 4000 Dive light that was given to us recently. The previous ower passed away. There was no booklet. The batteries are rechargeable and we were wondering how long to leave on the charger. This information would be truely appreciated. Thank you.

    Bill  (Certified Scuba Instructor at

    The first time charging the battery should be for 24 hours. After that typically 3 to 6 hours to re-charge the battery, depending on how much the light was used. You can also contact the manufacturer directly (609) 298-9331.

  • Sarah:

    I bought this light last year. We took it to Bonaire last summer and the first dive it "blew" up coming out. I think it got rapped on the stair railing. Water got in it and shorted out the batteries and blew the bulb. Is it possible to get replacement parts for it?

205 lumens of warm incandescent light are sure to bring out the true beauty of the ocean. While LEDs have recently taken the forefront in the dive light world, Xenon dive lights are still preferred by many divers for their lighter weight and color temperature that has the ability to bring out the natural colors of the reef. And with 8C batteries and a burntime of ten hours, the Shockwave II is made to provide divers with the best night dive experience possible.

This beam pattern is an excellent choice for multipurpose activities. At close range, focused wide beams simulate normal daylight conditions and allow you to take advantage of your peripheral vision.

Multiple settings on many of our products give you the flexibility to adjust your light’s brightness and/or beam width to illuminate greater distances or to conserve battery power, depending on your needs.

Underwriters Laboratories Inc. (UL) is an independent, not-for-profit product-safety testing and certification organization. They have been testing products for public safety for more than a century. In order for a product to bear the certified UL Mark, it must pass all UL requirements at their testing facility. Princeton Tec lights that are UL certified fall into one of the following classifications: Class I – Division II – Groups A, B, C, & D or Class II - Division II – Groups F, & G. Refer to the comparison chart in the rear of the catalog. Class I – Division II – Groups A,B,C,& D will be noted with one (+) Class II – Division II – approved for Groups F, & G, will be noted with two (++).

The highest of Princeton Tec’s ratings, Level 3 is assigned to lights that offer a degree of water protection equivalent to IPX8 in the International Electrotechnical Commission (IEC) standards. Lights rated at Level 3 provide waterproof integrity for continual submersion in water at depths down to 100 meters.

WEIGHT - 1021
Princeton Tec’s advertised product weights always include batteries. For many products, battery weight is a large percentage of overall weight. Weight can be significantly reduced by using lithium batteries in lithium-compatible products.

XENON BULBS come closest to replicating the color temperature of daytime light. They also generate about twice the brightness and consume about half the power of traditional halogen bulbs.

Halogen and Xenon Lights are well-suited to applications where a long-throwing beam is required such as caving and search and rescue. They are less desirable for longer-term, backcountry uses, where weight and battery efficiency are a must.
