Efficiency & Efficacy

Total Lumens vs. Delivered Lumens

Delivered Lumens / Ronald Motsch

Total lumens has been a long-used term in lighting to describe the total light output of a given light source. Now it is common to see delivered lumens in it’s place, particularly with LED products. Understanding the difference between these two terms will help explain one of the reasons for the ascension of LED technology […]

LED Efficacy…

Efficiency versus Efficacy / Ronald Motsch

How much value are you getting from your lighting? That depends, in part, on the fixture’s efficacy. Technically, efficacy means lumens divided by watts: the higher the efficacy of a fixture, the more light it will produce with a lower wattage, which saves energy on a per watt basis. Read More…
