Lux lumen converter11/6/2023 ![]() Lumen is a physical unit that describes luminous flux. Therefore, the word “lumen” came into being, and choosing lamps by wattage is no longer so popular. They work differently than traditional light fixtures, and they tend to use less heat while producing the same level of light output. This means that the efficiency of converting electrical energy into light energy is very low for incandescent lamp.Īs technology advances, these bulbs are replaced by more efficient and energy-saving lighting devices, such as LED (Light Emitting Diode) and CFL (compact fluorescent light). In an incandescent lamp, the current passes through the filament inside the bulb to generate heat and brightness, but the heat accounts for a large proportion, and this is not what we need. Generally speaking, the higher the wattage, the higher the brightness of traditional lamps such as incandescent and fluorescent lamps, so at that time wattage became a measure of brightness. When I was young (20th century), people bought lights by looking at the wattage of the bulb, for example we often needed a 100W incandescent to light our living room. Watt is a unit of power that measures the energy consumed by lighting fixtures. Watts to Lumens, Lumens to Lux What are Watts? ![]() These parameters we think are well very necessary to be well studied. Finally, we can check the illuminance level of the illuminated space through a lighting simulation or lux meter. Lumens measure the amount of light produced by an LED fixture, and this allows you to compare the brightness of different fixtures (under the same usage conditions). However, wattage doesn’t tell you how much light is actually being produced, and that’s when you need to care about another metric – lumens. Generally speaking, the higher the wattage, the brighter the light. When you’re shopping for LED fixtures, you’ll want to look at the wattage to determine how much power the LED fixture needs to produce light. LEDs have taken off in the 21st century primarily because they can produce the required amount of light at a lower wattage (energy consumption). Knowing the difference between wattage and lumens, as well as calculated lux, can help you choose the right fixture for your application. ![]() Lux is the lighting effect achieved by the lamp after installation. Wattage is a measure of the energy required by a light fixture to produce a certain amount of light, while lumens are a measure of how much light is produced by light fixture. Wattage and lumens are two commonly used measurements of light output when shopping for light fixtures.
