Kelvins, watts, CRI, CFLs, LEDs. What does it all mean? In this episode, Devyn gives a history of the light bulb starting with the incandescent and ending up with his beloved LEDs. (It's true!) Memory lane is real, and we go there.

Later in the episode, Devyn completely demystifies the overwhelming light bulb aisle for Stacy and anyone else who can't figure out which bulb to buy for their antique fixtures.
