Dimmable LED-High Output Ring Light maximizes light output at a greater working distance. Its 80 high-output LEDs  draw on 18-watts of energy while producing up to 5800 footcandles at 4.5" working distance. The LEDs are distributed among 2 concentric rings of light (each containing 40 LEDs) and are controlled via 8 quadrant switches. A 50,000 hour lumen lamp life makes this an ideal lightsource for the inspection of surface cracks and defects, welds, lead-free solder joints, flux residues and hairline stress cracks as well as a suitable replacement for traditional 150W Fiber Optic illuminators.
