CoolLED welcomed neuroscience researchers to CNS China 2026, with the pE-300<sup>opto</sup> drawing strong interest for precise, accessible optogenetic illumination
Why developing illumination for an OEM instrument involves rather more than choosing a bright LED, attaching a lens and pointing it in the right direction…
What actually happens between switching on the light and seeing an image? From LED illumination to fluorescence image, it’s a surprisingly busy day for a photon…
A day in the lab with metal halide versus LED illumination, from warm-up delays and heat to bulb changes, downtime and disposal
Have you ever felt like your microscope has a slight vendetta against you? It seems to works okay for everyone else, but for you it’s like trying to convince a really tired toddler to put their shoes on? Chances are, it might not be your fault…
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.
