800 Lumens to watts is typically 8 watts using LED, but is dependent on the efficiency of the light source. The outdated metric of using wattage to judge brightness is over, as LED lights use less power to produce the same amount of lumens and can differ according to design. So a new comparison needs to be made.
The Convert Lumens to Watts Calculator is an indispensable tool designed to bridge the understanding gap between lumens and watts, two pivotal metrics in the realm of lighting. Lumens measure the total amount of visible light emitted by a source, while watts quantify the energy consumption required to produce this light.
As an example, a 60W incandescent light bulb may produce around 900 lumens, giving it a luminous effacy of 900/60 = 15 lm/W. What wattage light bulb do I need?
A 60-watt incandescent bulb consumes 60 watts of power. A 10-watt LED uses less power but may emit the same or even more lumens than the 60-watt incandescent. Lumen tells you the brightness of a light source. Watt tells you how much energy it uses. Choosing energy-efficient light sources (e.g., LED) allows you to achieve high lumens with low watts.
Watts (W): This is the electrical power consumption you’re trying to find. Lumens (lm): This is the light output of the source you know. Luminous Efficacy (lm/W): This value represents how efficiently a light source converts electrical power into visible light. It varies depending on the light bulb type.
Higher lumens mean the light source is brighter. It focuses on the amount of light perceived by the human eye. Example: A candle emits around 12 lumens. A 60-watt incandescent bulb emits approximately 800 lumens. Watt is a unit of power, which measures the rate of energy consumption by a device, including light sources.
