80W90

80W90 is a type of incandescent light bulb, commonly used in general lighting applications. It is part of the Edison screw (ES) series of light bulbs, which are characterized by their screw base and wattage.

The "80" in 80W90 refers to the diameter of the bulb's base, measured in millimeters. In this case, 80 mm is the standard size for an ES bulb. The "90" refers to the length of the bulb, also measured in millimeters. An 80W90 bulb is 90 mm long.

The "W90" in 80W90 refers to the wattage of the bulb, which is 90 watts. This wattage rating indicates the power consumption of the bulb. The higher the wattage, the more light the bulb will produce, but also the more heat it will generate.

80W90 bulbs are available in various voltages, including 120V and 240V, and they are typically used in residential and commercial settings for general lighting purposes. They are known for their warm, yellowish light, which is characteristic of incandescent bulbs.

It is important to note that incandescent bulbs, including 80W90, are being phased out in many regions due to energy efficiency concerns. They are being replaced by more energy-efficient lighting options such as compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs).

The lifespan of an 80W90 bulb is typically around 1,000 hours, although this can vary depending on the specific bulb and how it is used. Proper disposal of incandescent bulbs is also important, as they contain mercury and other hazardous materials.
