Changes

It’s tempting to start by discussing the application of lights, because this is like not running out of hot water or never having the toilet plug. You don’t want to spend cruising hours pissed off because you can’t read comfortably (or whatever). But to make the best choices for different applications, we have to take the long road through the technology of lighting. Illumination and colour are the main aspects of lighting. Energy efficiency obviously affects the load on the electrical system but taken in isolation will not deliver the most comfortable living environment.
