Philips 9W Bulb Cool Day White

A LED bulb is a type of light bulb that uses light-emitting diodes (LEDs) to produce light. Unlike traditional incandescent bulbs, which use a filament to produce light, LED bulbs produce light through the movement of electrons in a semiconductor material. LED bulbs are known for their energy efficiency and long lifespan. They use up to 80% less energy than traditional incandescent bulbs, and can last up to 25 times longer. They also produce less heat, making them safer to use.

LED bulbs come in a variety of shapes and sizes, and can be used in a variety of applications, including residential lighting, commercial lighting, and automotive lighting. They are available in different colors, from warm white to cool white, and can be dimmable or non-dimmable depending on the specific model.
