  In a previous post, I’ve discussed sustainable aluminum as a path to further improve the sustainability of lighting. Another important metal to the lighting industry is copper. Copper is also critical for electrification, electric motors, electric vehicles, and many renewable energy technologies. The Copper Mark is a labeling program for copper producers to demonstrate [...]

  Some LightNOW readers are likely familiar with the existing white light laser approach of a blue laser diode (LD) pumping a phosphor to make safe, high intensity, white light. The challenges with blue LD + phosphor are: low CRI for phosphors that can withstand the intensity and heat, only high CCTs for these phosphors, [...]

  In the lighting world, we usually think of reducing carbon by increasing efficiency of energy use. However, there is a new push to reduce the carbon used to create construction materials, known as embodied carbon. This matters in the fight against climate change. Building materials and construction comprise about 11% of global energy carbon [...]

I’ve written previous articles about the gradual shift in US imports away from China toward Mexico, India, Southeast Asia and Eastern Europe, here and here.
