Rating: Bright!
Reviewer: Karen Singleton  -  View all my reviews
LOVE this dive light! Much more lumens and directional control than any of the rentals I have used. I really wish I hadnt put off getting my own dive light for as long as I did! Also, if you travel without batteries (and buy them once you get to your dive destination), it doesnt add that much weight to your luggage!

Rating: Ive seen the light
Reviewer: Gerald Buurma
The Shockwave is awesome. It produces a clear, bright light that lasts for hours. I use it with an action cam mounted on the top. It allows me to point and shoot high resolution video in a balanced light with enough spectrum to bring out the natural colors. I havent used it at night but Ive been in a few caves that were dark enough to need supplemental light for crystal clear video. The Princeton Shockwave lasted about two hours exactly the same length of time as the batteries on my action video camera lasted.

Rating: Great product - Love it
Reviewer: Finau I.
This is a great product and the battery life lasted a long time. Using cheap batteries from China (granted most of our batteries are made in China) still last my brother (I bought the light as a gift)a whole month before switching the batteries. I have to order two more Princeton Tec Shockwave L.E.D. Light for his other friends. I order one as a fathers day gift for my husband and so far, hes a happy camper.

Rating: Shockwave LED, great light.
Reviewer: Steve B.  -  View all my reviews
I purchased this light knowing full well the spotty reviews it has received on the switch. I thought I would take a chance on it as the price was right. Upon receiving the light I was impressed with the quality. The first dive with the light was in very poor visibility (5-10 at times) and depth of 80. This light worked like a charm. To be honest, I dont know what the fuss is about the switch. Once I became familiar with its operation, there were no issues. It works great. I have about six dives with the light now (including a night dive) and no issues. I recommend this light.

Rating: Genuine Fish Burner !
Reviewer: Robert M D.
Out of the box, 2 night dives in Roatan, Honduras. Mainly used the low light setting which was plenty of night light and gives you extended battery life. Only minor complaint is on/off/lowbeam/hi-beam switch worked hard and required two hands adjustment. I couldnt just click between the beams with one hand on the light. Ditched a 4-D cell light in favor of this one with 4 C cells and LED light. Clearly an improvement in weight, ease of handling, and underwater light. She wants to replace her old style 4 D cell primary diving light as well, and were going to order another one of these for her. Good piece of equipment !

Took it out for a try after receiving it. Worked well,light was bright,not as heavy as I expected it to be.Would have liked the switch to be a little easier to use but not a big issue. Seems to be a good product for the price.

Reviewer: Barbara T.
Although expensive it is really well made and the color makes it easy to see even in poor visibility waters. Wrist strap is good size - not too big and not too small. Light has good power and it is not too heavy or bulky. Good purchase.

Rating: Turn " Night to Light"
Reviewer: william hanson
I am very satisfied with this light. Why did I get it? My light was an oceanic ocean pro. 25 years old, 6 volt battery, and just wore out. I was optimistic that such a compact light could deliver so many lumens, be so compact and work as described in the literature, delivered to my door in less than a week, with batteries included, free shipping. AND IT WORKED AT A 115 FOOT depth on two boat dives on the same day........... Love it, Bill

Rating: bright for less
Reviewer: john u.
Princeton Tec Shockwave is a bright though somewhat heavy (with 8 C cells) light that really lights up overhangs and reef walls. I would recommend it for anyone not concerned about the extra bulk and weight

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.

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.

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 (++).

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.

The highest quality LED available from Lumileds, Princeton Tec’s Maxbright LED is extremely bright and efficient. This single LED emits a smooth, powerful, white light useful for a wide range of tasks. Princeton Tec uses collimators or reflectors with the Maxbright LED depending upon the application

The light output of Princeton Tec lights is measured in lumens. A lumen is unit derived by the International System of Units (SI) for measuring light output.

A collimator gathers all available light from an LED in the form of scattered rays and re-emits the light as parallel rays, making it more optically efficient than a standard reflector. Princeton Tec calibrates each collimator to the type of LED and application of each light. With proprietary optimized collimator / lens systems, Princeton Tec continues to advance LED technology.

Princeton Tec has developed proprietary ultralight heatsinks to protect LED products from overheating. Even though LEDs operate at much lower temperatures than traditional incandescent bulbs, they still generate heat. If this heat is not dissipated, the LED will suffer irreversible damage. By using heatsinks, Princeton Tec lights can burn at extreme brightness levels for long periods of time. The heatsink may be incorporated internally or externally depending on the product and its application.

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.

Princeton Tec Shockwave L.E.D. Light

Some companies just can’t help themselves when it comes to improving on a good thing. I’ve owned a Princeton Tech Shockwave since they first hit the stores some years ago. I was at the time replacing an older 8 D-Cell light with a lantern grip that had given years of good service but felt like I was underwater with a 55 gallon drum with handle on it. Heavy, cumbersome and a battery eating monster! We won’t even discuss bulb life. It was always a good idea to carry a spare, and it soon became obvious what to expect when you discovered that internally it had a space to store the extra one!

When I first came across the shockwave I was impressed by not only it’s weight, feeling like a feather compared to my old faithful monster light, but how wonderfully balanced it was in my hands. The batteries lasted a little longer and the spare bulb was still something handy go keep around. Alas, after many great years of service it finally works no more. So I went looking into lights and I was completely expecting the same wonderful degree of improvement all around. Maybe a light the size of a cell phone that will light up the entire ocean! To my dismay I found what appeared to be my trusty old Shockwave was still state of the art. That feeling of disappointment was soon erased when I gave a closer look. The light now uses 3 LED bulbs that have a life expectancy greater than most of us will ever spend underwater, let alone doing night dives. The battery consumption on LED bulbs is so low that it offers anywhere from 12 – 20 hours of good strong burn time. The trigger is still conveniently located to be easy to use, with a very secure trigger lock to keep from using your batteries up by accident.

But it is underwater where this light really “shines” (pardon the pun). LED lights don’t compare with the Xenon or Halogen counterparts when comparing lights over the counter. But under water LED light penetrates differently and gives not only a much better reach with the beam of light, but you also get a truer color! The difference is pretty remarkable! The Sealife you come across looks bright and brilliant, and the vibrant colors of a once dull looking reef can make you think it’s the first time you’ve visited your old favorite dive spot! If all remains the same, it looks like it’s going to be some years before I am back looking for the next new improvement in dive lights.
