Amaze yourself by seeing new colors not normally revealed in the beam of your old tag along dive light.

Recently you may have heard that some resorts are beginning to offer what's called a Fluorescent Dive or Flo Dive" where night divers are given UV lights that transform the reef into a spectacular show of color, just like the UV posters of yore. This phenomenon is relatively new to divers but, in fact, scientists have been observing this reaction for years. It is only recently that advances in technology have allowed the world of UV to be brought into the mainstream diving industry.

How does it Work:

Chemical compounds contained in the tissue of these animals (mostly corals) react to the UV light causing them to fluoresce in brilliant reds, purples and greens. The results can be quite amazing. Recently, advances in technology have made possible a new version of the UV LED which has a wavelength just outside the spectrum of visible light at about 395 (nm). This LED still causes marine life to put on their fluorescent show but since it is nearly invisible to the naked eye, only the glowing colors are revealed. The reef is still bathed in UV light you just can't see it! Bottom line no yellow filter needed.

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 see 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.

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.
