I was wondering why the Princeton Tech LED was rated so much better than the Underwater Kinetics cannon eLED light.
Hello Mark, the http://www.scuba.com/scuba-gear-55/026166/Princeton-Tec-Shockwave-L.E.D.-Light.html is better than the http://www.scuba.com/scuba-gear-55/026473/Underwater-Kinetics-C8-eLED-Light.html. Both lights have 5 star rating so you will not go wrong with either light. I think the Princeton does so well is: has a better light output, comes in 2 other colors and is half the price of the UK light.
400 Lumens of PTec power that's built to go 100 meters below the surface. This means you can have our most powerful handheld light illuminating any situation work or play throws your way. With two modes of illumination, you can choose between full-power and extended-battery mode. Whether you need spotting at a distance or close range lighting, the Shockwave LED is the biggest, baddest, brightest light you can buy.

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.
WATERPROOF - LEVEL 3
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.
LED OPTIC COLLIMATOR
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.
FOCUSED WIDE BEAMS
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.
8 C cell batteries
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.
