Conventional mercury based illuminators such as arc lamps and metal halide lamps require a warm up period before use and a cool down period after switch off before they can be safely used again. As a solid state device, LEDs switch on/off instantly and need only draw power when illumination is required.  Many laboratories leave the mercury based illuminators switched on all day to ensure its availability when required.  When an LED based illumination system is used, power consumption is significantly lower.

In addition to saving energy, the carbon footprint from using LEDs is trivial compared with mercury lamps.

Energy Consumption

Andy Evans of Green Light Laboratories has carried out independent testing of a CoolLED Illumination System compared with a traditional mercury bulb.  The case study detailing energy consumption data, and associated costs is detailed below:

Proving our commitment to shaping a more sustainable future for microscopy around the world, the pE-300 Series is now ACT Label certified.

With almost 40% of energy at university campuses being used by laboratories, steps need to be taken to increase the sustainability of lab technology. That’s why we’ve strived to achieve ACT Label accreditation for the pE-300 Series.

What is ACT?
Introduced by My Green Lab, the ACT Label stands for accountability, consistency and transparency. It’s a means of measuring the Environmental Impact Factor of a product by reviewing the environmental impact of the product itself, its manufacturing process, packaging and disposal.

Why have ACT labelled products in your lab?
It allows institutions to purchase lab equipment with the knowledge they are not only helping the world they live in-but keeping energy, water and disposal costs down for themselves.
