The HIGHLIGHTER multi-directional LED ring light uses a simple mouse to control the direction of the lights, as well as the intensity and number of LEDs illuminated. This unique new ring light works on all makes of microscopes. By rotating the LED lights in the HIGHLIGHTER, users can view lab samples from multiple angles without ever having to move the specimen being viewed. Problems with glaring and shadows can be virtually eliminated by adjusting the direction and intensity of the light and number of LEDs illuminated. Up to 40 LEDS can be directed either clockwise or counter clockwise simply by rotating the ring light’s mouse control. A left mouse click activates automatic continuous rotation of 1 to 39 LEDS so the operator can compare and contrast the image under different lighting, without having to move the object being viewed. A right click of the mouse alters light intensity to meet optical instrument and individual requirements.
