Sustainability

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.
