Today I take a look inside a party disco light. It's simply an RGB LED lamp with a rotating disco globe (dome) on top of it. It projects moving red, green and blue beams. It has an E27 (E14) screw base, so you can install it into any ceiling light or table lamp. It runs on 230V 50Hz mains and draws about 3W. I reverse engineered the full schematic of it. The power supply was a bit different than I expected :).
WARNING: Mains voltage is dangerous. Risk of electric shock and death!
