The electricity consumption of a spotlight can vary based on its type and wattage. Traditional incandescent spotlights typically use around 50 to 100 watts, while LED spotlights are more energy-efficient, using about 10 to 20 watts for similar brightness. Therefore, the actual electricity used will depend on the specific spotlight model and its wattage rating. To calculate usage, you can multiply the wattage by the number of hours it’s used and divide by 1,000 to get kilowatt-hours (kWh).

This technique helps to capture the desired level of light and shadow in your photos.
