About Underwater Kinetics Sunlight C4 eLED Dive Light

The C4 eLED waterproof light is Underwater Kinetics lightest weight primary light. It is designed to fit smaller hands while still offering brightness comparable to lights twice its size. Its water-cooled heat sink actually increases brightness underwater and improves burn time. For maximum illumination and a comfortable fit, the C4 is the perfect solution. Unlike the standard glass envelope lamps used since Edison, the LED will not break when dropped. The life expectancy is well over 5,000 hours.

The light emitted by the LED (light emitting diode) is similar to sunlight and travels farther underwater than the more yellow light from an Edison lamp. In addition a power control circuit is built into the light to help maintain the same brightness throughout the discharge of a set of batteries. A tough O-ring sealed ABS and polycarbonate case protects the components all the way down to 500' (152.4 meters). The small size of the C4 eLED makes it ideal for revealing the incredible marine life hidden under ledges.

The C4 eLED is powered by 4 disposable C"-cell alkaline batteries (included), or if you wish to upgrade it with a rechargeable kit the SKU: UKTRKC4E is available eliminating the need for replacement power cells.

    I have been very happy with this purchase! I have used this light a number of times with students during Open Water and Advanced in a local quarry. It's very dark below about 30 feet and although I have a strobe on the back of my tank the students have difficulty seeing me beyond about 4 feet when I take them "on tour". I typically take the light and shine it over my right shoulder and students say it is a great beacon for them to follow.

    Also, I've not had to change the batteries although I've logged at least 16 hours or more on the originals. The owner's manual suggested 4-6 hours of burn time, but I've far exceeded that and haven't noticed a reduction in power.

    The grip is comfortable and shaped nicely to reduce fatigue and make one hand operation easy.

    Great light!

      Comments about Underwater Kinetics Sunlight C4 eLED Dive Light with Pistol Grip:

      Great light for night dives. Strong, concentrated light beam. Turns on and stays on. A bit heavy and takes a bit of getting used to (particularly if you are petite) but thus far has been worth the investment. I have not had it long enough to assess bulb life or battery drain.

            Comments about Underwater Kinetics Sunlight C4 eLED Dive Light with Pistol Grip:

            I am impressed with this light. I have only had this light for a couple of weeks and used it on 7 times. I have very big hands but it still handles fine, even with gloves. The beam is clear, bright and well defined. I am very impressed with the white LED light as well. It allows for much better visibility into holes and gives better definition of objects.
            The switch works really well. Its a least as good as any pistol lights I have owned, and that's quite a few. Use the lock off device when its not in use because it turns on easily.
            Interesting heat sink sticking out the front of the lens but it seems to do the trick.
            I really didn't see a big difference between high and low power setting. Low works the best for me anyway. I can't say about the battery life I still have the first set in use.
            Overall an excellent product so far.

              Comments about Underwater Kinetics Sunlight C4 eLED Dive Light with Pistol Grip:

              I was really happy with this purchase as it was easily transportable overseas and was not too heavy. Previously had a halogen dive torch and this lamp was 10 times better. I recommend a caribina style retractor as it is light enough to hang to a D ring when not in use, too big too put in my BC pocket. Not a great deal of difference in the two light settings, however excellent for night dives.
