A higher number of lumens will mean a higher brightness level and vice versa. Lumens are the measurement of output light brightness of lighting bulbs. So, the term ‘lumens’ came into being, and wattage ratings became unpopular. Such lamps gave off a high level of brightness output at a fraction of wattage. Their working principle is different from older lamps.
So wattage became a measure of brightness.Īs the technology improved, these lighting bulbs were taken over by much more efficient and energy-saving lighting fixtures such as LEDs and energy-saving CFLs. Higher the watts, the higher the brightness level of the output light. The higher wattage meant higher brightness for lamps such as incandescent, fluorescent, etc.įor example, in incandescent lamps, the electricity passes throughout the filament inside the bulb to produce heat and brightness. In olden times, people bought lights by looking at the wattage of the bulb. Watt is the unit of power that measures the energy usage of the lighting fixture. However, this practice has become obsolete as new energy-efficient bulbs entered the market that gives off the same number of lumens (or the brightness level) at a lower wattage. It was common practice to look for the ‘Watts’ before buying a lighting bulb in the past. Light Bulb Facts: The Meaning of Lumens.
