Ring lights made of fluorescent and LED materials are more affordable and provide cold illumination without any shadows. Large thumb screws make it possible to attach practically any brand of microscope with ease. The most cost-effective alternative is the newly redesigned fluorescent ring light, while white LED models with a 10,000-hour lifespan produce the most potent, concentrated lighting. The new 60-bulb LED ring light is configurable and programmable for segmented quadrants to throw shadows as needed, while the cost-effective 48-bulb LED ring light has variable intensity control.
