What is wattage?
Wattage indicates how much power is needed per unit of time to operate, for example, LED lighting. This varies by device. Wattage is always indicated with the product. Wattage is denoted by the letter "W". The unit is named after the Scottish engineer James Watt. Wattage can be calculated using a simple formula. The formula is as follows: the number of Volts x the number of Amperes = wattage. It indicates how much energy your LED lighting consumes.
Wattage in LED Vehicle Lighting
When we talk about LED vehicle lighting, the wattage is often significantly lower than with traditional halogen lamps, because LEDs are more efficient at converting electrical energy into light. This means that, for example, those beautiful spotlights on the truck consume less energy for the same amount of light, saving the battery and improving the vehicle's efficiency.
Units of Watt
Since wattage can vary significantly, there are different names for different units. For example, 1000 watts is 1 kilowatt. The units of watt are shown in the table below.
| Units of watt | ||
| Factor | Name | Symbol |
| 10−6 | microwatt | μW |
| 10−3 | milliwatt | mW |
| 1 | watt | W |
| 103 | Kilowatt | kW |
| 106 | Meagwatt | MW |
| 109 | Gigawatt | GW |
| 1012 | Terrwatt | TW |
| 1015 | Petawatt | PW |
Wattage in kWh
On your energy bill, you have probably come across the abbreviation kWh. This stands for kilowatt-hour. One kWh is 1,000 watts for one hour. The "k" stands for kilo, which means a thousand. The "W" stands for watt, and the "h" stands for the English "hour." For example, if you have a LED work lamp that consumes 48 watts and it operates for one hour, it is equivalent to 48 watt-hours or 0.048 kWh.
