What is Lux Level ?Lux Level is often used as a messurement to indicate the illumination intensity of a light source at a certain height, its formular is Lux Level = Lumens/square meter or lumens / square foot, its unit lux or foot candle.
e.g. a retail shop proper lux level about 30-40lux, or 3-4 footcandle
A customer can use a light meter to detect the lux level of your room.
While to design a lighting system, we need our engineer to conduct a Dialux test simulation with software and can judge if our light fixtures is good for your lighting application.
What is THD In Lighting?
THD is abbreviation of total harmonic distortion, a meassurement of mutual elec-magnic distortion draw between the electronic components. The lower the value is, the better for the entire system, which means higher power factor and energy efficiency for the system.
For LED lighting, the good THD value should be kept as low as 20%, the best THD is less than 15%.
