TL;DR
Lumen output is the measure of the total visible light a fixture or lamp emits, the figure that replaced wattage as the honest way to compare brightness across LED products. Outdoor lighting works at far lower levels than interiors: a path light may emit 100 to 200 lumens while a security floodlight reaches 1,200 or more.

Lumen output is the measure of the total visible light a fixture or lamp emits, the figure that replaced wattage as the honest way to compare brightness across LED products. Outdoor lighting works at far lower levels than interiors: a path light may emit 100 to 200 lumens while a security floodlight reaches 1,200 or more. Designers balance it against beam angle and color temperature so a yard reads as layered light rather than glare.
