Welcome to CoolLED

CoolLED designs and manufactures cutting edge LED illumination systems for researchers and clinicians using the latest LED technology.

The company has specialised in fluorescence microscopy since it introduced the first commercially available LED illumination system in 2006. LEDs are now the system of choice because they are more stable, longer lasting, and energy efficient than traditional mercury based illuminators as well as offering superior safety and environmental features.

Why choose CoolLED?

  • Simple, high-performance products
  • Fast, friendly and expert support
  • Reliable delivery (>99% on-time)
  • Sustainable technology

What Our Clients Say

Dr Martin Spitaler
Head of Imaging Facility, Max Planck Institute of Biochemistry

We are extremely happy with our CoolLED pE-300white System. Integration with our microscope was simple, and the robust system has never needed maintenance or alignment. I am particularly happy with the user interface as it is simple and intuitive.

Dr Michael Craig
Research Fellow, University of Exeter Medical School

I have been using a pE-4000 for optogenetic experiments using in vitro slices for just over a year now. The pE-4000 has been fantastic for my needs: the ability to simultaneously use multiple wavelengths of light has allowed me to carry out experiments using two different opsins to study how external inputs converge on hippocampal interneurons. I’m currently setting up my own research group at the University of Exeter, and all of my patch-clamp rigs will have a pE-4000 on them, as they are such versatile devices for optogenetic experiments.
