Harvard Strategic Procurement has negotiated discounted pricing for Lumencor light engines for Harvard laboratories. This sustainable option for light boxes is currently being utilized at the Nikon Imaging Center at HMS.
The Nikon Imaging Center at Harvard Medical School is the largest light microscopy facility on the Longwood campus and now thanks to a new approach to lighting it’s also positioning itself as the greenest. The Center is transitioning the light source for 12 of its 13 microscopes to more efficient solid-state light engines, replacing older metal halide bulbs that contain mercury.
For Dr. Jennifer Waters, the Center’s director, the transition to the more environmentally-friendly light source was primarily motivated by a desire to improve the quality of research data rather than the energy or cost savings the lab would realize (though those certainly are an added benefit). It is estimated that the newer light engines will last for approximately 10,000 hours versus the 1500 hours lifespan of the older bulbs. Because the solid-state light engines can be turned on and off in an instant they will last much longer, dramatically reducing the Center’s replacement and disposal costs. The previous metal halide bulbs also contained mercury, a harmful and toxic chemical element that needed to be disposed of in coordination with Environmental Health and Safety.
