These two dimensional fluorescent bulbs are actually three white LEDs. The 'bulb' is a laser cut and engraved piece of acrylic. Stuck to one side of the acrylic is a piece of sticky copper, which is connected to a touch sensor. The light turns on with a simple touch, and off again with another touch. All the electronics are contained in the box base, with a hole for the AB to USB cable to plug into a wall transformer or other USB power source.
