Our High Frequency Fluorescent Ring Lights feature tri-band phosphor bulbs with many different color options and easy lamp replacement. Staying cool to the touch, the polycarbonate plastic housing does not radiate heat that could affect samples. Ring configuration allows 360° diffuse illumination with strong intensity even at long distances. These Fluorescent Ring Lights are useful in inspection and assembly environments. They are also especially well suited for video and machine vision applications, providing flicker-free, high frequency output. When illuminating reflective objects, our Polarizer/Analyzer Accessory Kits are easily integrated and can improve image quality by reducing glare. Variable intensity option allows for 10 – 100% adjustment. Fixed versions feature a 7ft cord length from end of unit to plug-in wall transformer; Variable versions feature a 6ft cord length from unit to control ballast and 7ft input power cable.
