SNBL USA is pleased to announce that we have completed the lighting portion of our energy conservation project. Since 2017, more than 2,400 fluorescent light fixtures have been replaced with more efficient light emitting LED technology. Our animal vivarium, analytical laboratories, office spaces, common areas and external security lighting have all benefited from the recent upgrades. These enhancements will also decrease the facility’s energy consumption by approximately 62%, which supports our commitment to minimizing negative environmental impact in our community.
Before we initiated the installation of the LED lights, a thorough review of available literature was conducted to ensure there would be no adverse effects on our laboratory animals. Existing research suggests that LED lighting has no discernible impact on common laboratory species and may actually provide a more beneficial environment. The article “LED Lighting and Circadian Biology” published by Laboratory Animal Professional, revealed that daytime exposure to LED lighting in rats had a seven fold increase in melatonin levels. In these animals, exposure to LED light (as opposed to fluorescent light) also “had a marked positive impact on metabolic and physiologic parameters associated with the promotion of animal health and well-being” (Dauchy, R. and Pierce, A.). Based on the positive feedback we have received from SNBL USA staff, we anticipate our employees are also enjoying the benefits of the new lighting.
