In simple terms, Lumens are a measure of the total amount of visible light from a lamp or light source. The higher the lumen rating, the “brighter” the lamp will work.
How does this compare with other light sources?
Familiar examples
• A typical 4 x D cell battery maglite will emit approx. 70 lumens
• The average path light using 2-3 LEDs emits 15-18 lumens
• A 25W incandescent globe emits approximately 160 lumens
