Underwater Kinetics SL4 eLED Dive Light

Overview

When you need to go scuba diving in very deep waters and you need a lighting device that can provide not only brightness but also an assurance of longevity and durability, then you need to consider a light like the SL4 eLED. In this Underwater Kinetics SL4 eLED review, we will be examining the intricacies and deep features that it brings to the table while showing it as an optimal lighting solution for the perfect underwater illumination.

The UK Kinetic SL4 dispenses some 400 lumens of brightness while showcasing some 10 hours of burn time. Combine that with the high intensity LED and incredible battery life of the SL4 eLED and you will know that you have a powerful and highly efficient dive light in your hands. This powerful dive light has a compact size and narrow penetrating beam that is very penetrating. Fit for use as a secondary dive light, the Kinetic SL4 tops the charts of international dive travel and can be used for recreational and professional dive use.

The high intensity LED and incredible battery life move the SL4 (L1) to the top of the chart for international dive travel. Compact size and narrow penetrating beam allow you to seeall the way to the back of an overhand on the wall, daytime or night. As an added bonus the SL4 is equally at home at work or around the house as well as in bad weather.

Underwater Kinetics SL4 eLED Review

The eLED circuitry provides relatively constant brightness throughout most of the life of the batteries. As the batteries are nearly depleted the brightness of the LED falls sharply but does not go out as happens with classical filament lamps. This brightness will persist for several days, making this light valuable for emergency situations. The SL4 eLED is also great as a photo spotting light or to illuminate gauges and dive tables.

The SL4 LED operates more efficiently and produces more light when it is cool. Underwater, the SL4 eLED burns brighter for almost half of the battery life, due to the unique way that heat is conducted away from the LED. The higher brightness consumes a little more power and slightly reduces the battery life. The SL4’s eLED Lamp produces 400 lumens of brightness with a beam reach (on land) of 622′ (189.6 meters). To reduce glare and protect the light, the SL4 comes with a molded rubber bezel cover. The rotary switch is easily activated with the thumb and index finger for single hand operation.

The Light is powered by 4 x C”-cell alkaline batteries (included) with a burn time of 10 hours. The light measures 6.2″ x 1.5″ x 1.7″ (15.75 x 3.81 x 4.32 cm), weighs 15.02 oz (425.81 g) and is depth rated to 500′ (152.4 meters). The SL4 includes an owner’s manual, adjustable rubber covered wrist lanyard and is proudly made in the USA. Light is covered by a limited lifetime warranty. The Underwater Kinetics SL4 eLED L1 Dive Light is commonly used for Cave Diving, Close-Up Viewing, Night Diving, Professional, Recreational, Safety Backup and more.
