CoolLED has been named Judges Scientific Company of the Year for a second consecutive year – the first time this has ever happened
We created a straightforward calculator designed to estimate how long your remaining mercury or metal halide lamps may last based on typical usage patterns
You can have an excellent light source, a great camera, rock-solid mechanics, and the right optics – but without tight coordination, you’re left with a setup that’s technically impressive but practically fiddly…
We are proud to announce the new pE-300opto, a light source designed specifically for neuroscience researchers using optogenetics
We recently attended EBP South’s ‘Get Inspired’ event, where Marina, Alex and Andrew spent a busy day speaking with young people about careers in STEM
We’ll be at SEMICON Korea and SLAS 2026, talking with industrial and life science partners about OEM illumination challenges and system design
Come and Visit us at FOM – Focus on Microscopy 2026 – to learn more about our LED Illumination Systems for Fluorescence Microscopy
The data you’ve been asking for is finally here – real LED illumination power data compared to metal halide bulbs
2026 is set to be a busy and exciting year for CoolLED, with a full calendar of exhibitions and events across life sciences, microscopy, photonics, and industrial inspection.
We are pleased to announce that our pE-400max Illumination System can now be operated directly with Evident/Olympus cellSens Dimension
As we look into 2026, our goals are simple, even if the work itself is complex…
Need something a little different?
For manufacturers who wish to gain a competitive advantage through bright, stable and controllable illumination, CoolLED’s world-renowned LED technology is available in customised configurations.

Did you know that LED illumination systems help laboratories reduce their carbon footprint, protecting laboratory staff along the way?
Toxic mercury-based microscope illuminators are bad news for the environment, draw a lot of power and have a short lifetime.
LED illumination systems are cleaner, have a long lifetime and use less power. Our pE-300 Series is also ACT label certified and is a natural choice for labs who want to play their part in helping the environment.
At CoolLED we are committed to giving our customers outstanding service right from the start and throughout the lifetime of the product. Please get in touch if you have any questions or would like a quote. You can also browse our site for technical resources and general support.
