We have a number of CoolLED units and have been impressed with how all units have integrated seamlessly with our microscopes. Using CoolLED instruments have been of huge benefit to the imaging facility due to the long lifespan, ease of installation and great technical support. Furthermore, researchers and users of the facility have benefitted as CoolLED illumination systems are so easy to use and offer excellent results. I would highly recommend CoolLED to any microscopy facility.
