In S2E7, The Age of Tiny Lights, Renee and Marc trace the story of LEDs from a childhood electronics kit with a single red indicator to the decades-long effort to make blue light viable. What began as dim, specialised components required breakthroughs in crystal growth and materials science before becoming practical at scale.

Once blue was possible, white light followed, and with it, a steady transition away from a century of filaments and discharge lamps. Today, semiconductor light sits inside streetlights, buildings, vehicles, and displays, shaping energy use and the look of modern infrastructure.

There’s reminiscing about warm glowing lights, some justified moaning about modern headlights, and more than a little nerding out about materials science.

Join Renee and Marc as they discuss tech topics with a view on their nostalgic pasts in tech that help them understand today's challenges and tomorrow's potential.
