Lumens are the measure of light emitted by a bulb
Lumens are the standard unit of measurement for light emitted by a bulb per second. The higher the number of lumens, the brighter the light. Conversely, fewer lumens mean a dimmer light. In many jurisdictions, lamps used for lighting are required by law to be labelled with their light output in lumens.
The lumen is defined as a unit of luminous flux in the International System of Units (SI) and is symbolised by "lm". One lumen is equal to the amount of light given out through a solid angle by a source of one candela intensity radiating equally in all directions. In other words, a light source emitting one candela of luminous intensity uniformly across a solid angle of one steradian emits one lumen (1 cd·1 sr = 1 lm).
The number of lumens emitted by a bulb is an important consideration when choosing lighting for security purposes. While darkness may be a burglar's best friend, outdoor security lights can easily make your home a less attractive target. For outdoor security lights, recommendations generally start at 700 lumens.
It is worth noting that lumens alone do not offer a complete picture of light effectiveness. Other factors to consider include power consumption (in watts, W), voltage (in volts, V), current (in amperes, A), colour temperature (measured in kelvin, K), and the colour rendering index (CRI). While lumens measure the brightness of a light, watts measure the energy consumed per second. LED lights, for example, are much more energy-efficient than incandescent bulbs and therefore have a lower wattage for the same number of lumens.
