Having efficient light bulbs is great. It saves energy which gives you lower electricity bills and lower impact on the environment. So why have we stopped using the very energy-efficient low-pressure sodium vapor lamps?
In this video, I take a closer look at this vintage technology and compare it to modern, state-of-the-art LEDs. How do they compare in luminous efficacy and color rendering index?
