We continually research and analyze our manufacturer’s offerings (as well as allied fields) to provide a list of products that make a positive impact on the environment. Our ideal product is one that has the highest efficacy source available, contains mostly recycled content that can be recycled at the end of life, and is made at an eco-conscious facility with components that have the longest life possible.
Until a global definition of 'green' is achieved for the lighting industry, Bagby believes that such products should be judged on the following criteria.
- Luminaire Efficacy Rating (LER): It’s well known that the energy used to manufacture a product pales in comparison to the energy consumed in operating that product over its life. Therefore, considering a product's LER, which gauges its overall energy consumption, is vital in determining its 'greenness'.
- Long-life components: Aside from consuming energy, lighting products also require replacement ballasts and lamps. We must consider the impacts of replacing ballasts on the environment and choose light sources that have the longest life possible to reduce landfill use. For instance, many 4000K CCT metal halide lamps have up to twice the life of their 3000K CCT metal halide counterparts.
- Recycled and Recyclable content:Unfortunately, little is known about luminaire recyclability. The industry is examining this currently so we can’t factor that in today, but it is important so we will continue to monitor this factor for you and integrate recyclability into our selection process as soon as possible.
- Impacts of Manufacturing: Finally, we need to consider the processes used in production. We need to ensure that the manufacture of lighting products doesn’t impact our planet any more than is absolutely necessary. Green policies in the manufacturing facility reduce the impact on the planet just like our choices to use energy-efficient lamps and ballasts.
We look forward to a green future full of sustainable lighting.
