Official SLX LED review by Scuba Diving Magazine (September 07)
The SLX may be the smallest primary light we tested, but it can light up the reef with the best of them. It uses a trio of 3-watt LED bulbs to produce a blue/white beam that brought out vibrant colors on a night reef dive. The beam is focused into an intense hot spot, and while the 12-inch perimeter measurements fall off about 50 percent, there is a visible halo that extends to almost four feet in diameter. Its aluminum case measures just 5.25 inches long by 2.5 inches in diameter and houses six AA batteries. Two O-rings seal the housing, and the on/off switch has a good lock to prevent accidental activation. A lantern handle provides a solid grip and can be replaced with a mounting bracket if you want to use the SLX as a camera focus light.
