Underwater Kinetics SL4 eLED (MK2) Dive Light



* NEW *

600 Lumens


The SL4 has been the gold standard for small utilitarian dive lights for decades. Owning a SL4 is owning a piece of scuba diving history. It is compact enough to slide comfortably into a BC pocket and has a bright center spot to light up dark spaces under any type of diving condition.

Now, UK is introducing the updated and enhanced Mark 2 version of the SL4. For the first time, we are using a digital controller to take maximum advantage of all four C-size batteries. The SL4 MK2 boasts an eye-watering 600 lumens of brightness, while retaining all the great qualities that made it the most popular dive light in history.

  • The 395 wavelength is almost invisible to the naked eye, so no yellow filter is needed
  • Brings out incredible colours and intricate details of marine life


  • Some animals have a stronger reaction to this wavelength than they do with the 395.
  • Yellow filters are usually needed to cut back on the excess blue light and all the fluorescent colours to come through.
