Recandescent is an artificial light source that combines traditional incandescent lighting technology with innovative nano-technology to create the most energy efficient but also the most holistically environmentally friendly light bulb ever.  Inspired by advances in hot mirror technology developed by academics at MIT, Recandescent proposes the application of this technology in a modular light bulb design supported by a circular economy business model.  

This has led to the creation of a light bulb that is more energy efficient than existing LED technology, but also to the development of a product where every component can be reused or recycled; material and components from the Recandescent bulb can be reused almost indefinitely, avoiding depletion of our natural resources.  This resolves the major problem with existing energy efficient lighting technology, where materials used in their production are damaging to people and the environment, and also fused together in such a way that they cannot be reclaimed, recycled or reused.
