All our lab members have been very glad that the microscope representative recommended CoolLED pE-300white to us. It is really cool! With this new and award-winning technology, we got rid of the big and heavy fluorescence power supply box and camera controller, and will never worry about the life time of a fluorescence lamp again, because we can use the pE-300white almost forever. Now we can turn the fluorescence on or off instantly and adjust the intensity precisely and conveniently with no shutters required. In addition, the illumination is clean, bright and stable across the spectrum, and it is not just safer for us but also energy-efficient for our environment. We love it! Thank you, CoolLED!
