Oh... I think if I did one, it would use a 16~18V transformer and 5 LEDs in series per string.
Or a switching power supply from a laptop (the battery charger cord), but it would not fit inside the bulb.

The only commercial LED sign I ever saw up close must have a supply for each LED.
"Each LED" was a cluster of 3 LEDs, red, yellow, and blue. I have a closeup photo, somewhere.
It is in New York City in the NBC building.  This photo is not so great, but it's all I found on the internet.
