Q. What are the advantages to using LED lights?
A. LEDs bring several advantages to the lighting industry, including high efficiency and durability, and, with superior life over other lamp sources, their required maintenance is greatly reduced.
This translates into energy savings, maintenance savings and an overall reduction in cost of ownership over the product's lifetime.
Q. What's the difference between efficiency and efficacy?
A. Efficacy is a term normally used in cases where the input and output units differ. In lighting, we are concerned with the amount of light (in lumens) produced by a certain amount of electricity (in watts).
On the other hand, efficiency is a term that is typically dimensionless. For example, lighting fixture efficiency is the ratio of the total lumens exiting the fixture to the total lumens initially produced by the light source.
Q. How do you evaluate LED products?
A. Lumen output is only part of the story and can be misleading. Read more
