Choosing The Light Source
When selecting the light source for your application, there are some things you need to take into consideration:
Color Rendering Index:
The Color Rendering Index (CRI) is a relative scale to determine a light source’s ability to render an object’s color. The higher the number, 100 being the best, the better the color rendering. Specify a source that has 90+ where color matching/selection is occurring; 80+ for pleasant appearance of people, food and merchandise; 70+ for offices, educational, health care and institutional settings; 50+ for most industrial tasks.
Color Temperature:
Color Temperature is measured in Kelvin and represents whether the light source appears warm (1,500K), neutral (3,500K), cool or daylight (5,500K). The chart below highlights the color temperature and how it affects the mood of the space.
Lamp Life:
Lamps can average 750 hours to 20,000 hours depending on the light source chosen. Average lamp life is the number of hours the lamp should last before it burns out. Lamp life is determined by how many hours at which 50% of the lamps installed are still expected to be illuminated.
