Episode 15: The Sun is Gone, but I Have a Light
/
Light. It is one of those things that we tend to take for granted until it isn’t available, and then, stumbling around in the dark, the value of light becomes all too clear. Humans have been figuring out better ways to light our homes for hundreds of years, but in the last 200 years lighting technology has truly advanced, and it all started with the creation of the electric light.
This fortnight's show discusses the history and future of the electric light, the world's oldest working light bulb, Lumens, color temperature, and the coolest lighting event that is going to happen in North America this year, the 2017 Solar Eclipse.
