Plano lightbulb company shines brightly on Shark Tank

A LED light bulb called ilumi fits into regular fixtures, but comes with a Bluetooth connection built-in. You turn it on, off, change between millions of color choices, and adjust the brightness — all with a smartphone app. Co-creator Swapnil Bora calls it a "total evolution in lighting." After he and friend Corey Egan came up with their 'bright' idea, friends prodded them to go to a local tryout for the ABC reality show Shark Tank.
