Yes so what you see there is an LED chip (the rectangle part) and then a lens in front (the dome portion).
The Joker head is a bit more simplistic than GL because they are higher powered, spaced apart chips, theoretically can be changed out, but tricky and specialized.
GL is more like a traditional LED wall, made up individual cabinets, with smaller bare chips located within ‘shaders’ that keep the sun off and make them brighter in the daylight.
- fun fact, the GL logo would be capable of displaying full video content (albeit only green) but at the time of it’s install it was not desired to implement that capability.
