2. Light Effects
The YouOKLight YK0004 bulb features red, blue, and green LEDs that combine to create a full-color spectrum. The crystal dome rotates automatically, producing a dynamic strobe effect similar to a traditional disco ball. The light patterns will continuously change and move across surfaces.

Maintenance
- Cleaning: Ensure the bulb is powered off and cool before cleaning. Wipe the surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: If storing the bulb for an extended period, keep it in its original packaging in a cool, dry place.
- No User-Serviceable Parts: The bulb contains no user-serviceable parts. Do not attempt to disassemble or repair it.
Troubleshooting
- Bulb does not light up:
- Ensure the bulb is securely screwed into the socket.
- Verify that the light fixture has power. Test with another working bulb if necessary.
- Rotation is inconsistent or stops:
- Check the bulb's orientation. It performs best when installed vertically (straight up or down).
- Ensure there are no obstructions preventing the crystal dome from rotating freely.
- Light output is dim or colors are incorrect:
- This is unlikely with LED technology, but if observed, ensure the bulb is receiving adequate power.
- Clean the crystal dome to remove any dust or debris that might be affecting light projection.
