Fireworks rockets are pyrotechnic devices that are propelled into the air and explode to produce colorful and dazzling visual effects. They are typically made of a cylindrical tube filled with explosive materials and a fuse at the base. When the fuse is ignited, the rocket is propelled into the sky and bursts into a display of bright lights, sparks, and loud noises. Fireworks rockets are commonly used in celebrations and events to create a spectacular and memorable experience for spectators. **

Trailing-edge dimmers are typically used for LED and electronic low-voltage lighting, as they provide a smoother dimming experience and help prevent flickering.
