![]() ![]() If a 100-watt incandescent light produces 1,500 lumens, and a 10-watt LED light does the same, the 10-watt LED bulb may claim 100-watt equivalency and energy efficiency. Wattage is a measure of how much electricity (or energy) a light bulb consumes to achieve its lumen output.Įach type of light source - LED, fluorescent, halogen or incandescent bulbs - has a different lumen-to-watt ratio. LED lights provide higher Color Rendering Index (CRI), so, while they more accurately reveal the colors of the subject being lighted, they don’t provide more light. Strictly speaking, 600 LED lumens provides the same amount of light as 600 incandescent lumens. The reference point: A standard 100-watt incandescent light bulb produces about 1,500-1,700 lumens. It’s also commonly known as brightness or light output. Lumen output is a measurement of the total quantity of visible light emitted by a light source. For exact analysis, please consult a lighting design professional. Use this calculator to calculate the lumens needed to light a room.
