What is Color Temperature? Color temperature is one characteristic of visible light measured by the

Kelvin scale. Generally, the human eye functions more effectively when viewing objects illuminated by a light source whose color temperature is closest to that of mid-day sun. From a work perspective, this translates to a safer and more productive work environment.

What is the Effect of Voltage on Bulb Life and Light Output? Halogen bulb manufacturers develop bulbs to operate at a “design volt-age” (Rated Voltage). Bulb light output and life statements are based under testing bulbs at their Rated Voltage. Operating a bulb at more than or less then its Rated Voltage affects both its life and its output.

NOTE: Total Bulb Light Output is measured in Mean Spherical Candle Power (MSCP)

What is a Lumen? Luminous Flux is the total “effective” output of a lamp. Luminous Flux is expressed in Lumens. The larger the lumens, the greater the output of the lamp.

What is a Candela? Luminous Intensity is light intensity through space. Luminous Intensity is expressed in Candela. The greater the candela, the brighter the light.

What Is Lux? Illumination (luminance) is light density falling upon a surface. Illumination is expressed in Lux. The larger the lux, the more light on the ground.

ExAMPLES 1 Lux = 1 lumen per square meter 5 Lux = 5 lumens per square meter

What is Foot Candle? Foot Candle is also a measure of light density falling upon a surface.

ExAMPLES 1 Ft. Candle = 10 lumens per square foot 5 Ft. Candles = 50 lumens per square foot
