Answer:
Hiroshi Morishima’s Wagami Andon demonstrates how the development of halogen lights has allowed lighting designers to use relatively flammable materials near the light source.
Explanation:
In halogen light bulbs illumination takes place when electricity produces enough heat to turn on a tungsten filament, therefore emitting light or “incandescence”. Even though it is safer than previous lighting technologies, nowadays LED lighting is considered much better, since it produces a lower temperature, being safer than halogen ligthing.
