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.
