The brilliant 40 LED display, with a 50,000 hour lamp life and 6,000 Kelvin color temperature, makes the LED3000 ring light ideal for the inspection of surface cracks and defects as well as for lead-free inspection. The elf-contained ON/OFF and dimming controls allow for dimming up to 15 percent output. The LED3000-PF consumes 9 watts of power and produces up to 3600 footcandles at 4.5 inches of working distance. A removable and replaceable diffuser cover allows for easy cleaning and LED array protection from damage and contamination. The unit is ESD-safe and features static grounding cables to ensure static dissipation.
