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.

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:
