• Luminous flux Luminousflux, on the other hand, means all light energy penetrating the face within fixed time. The measure of Luminousflux. is Lumen(=Im).
• Luminance efficiency emission of luminousflux by 1W. higher luminousflux use less electric, make more light. BackSan products is excellent for energy save effect due to high luminousflux.
• Color temperature When the sunlight distracted, light can be seen which looks different color according to temperature. Kelvin is used for measure of light temperature higher temperature looks blue color, lower temperature looks red color The average K as follows : the light of bulb type is 2,800k, the light of fluorescent is 4,500 ~6,500k, the meridian sun is 5,400k, the light of cloudy day is 6,500~7,000k. BackSan products K is 5,000~6,000, most similar to natural light.

• Color rendering The color rendering tells the color similarity when we see the color in natural light and turn on the lamp. The measure unit is Ra.
• Power factor The phase-contract between electric current and voltage in the AC(alternating current) In the AC, the electric power is that multiplies by factor to the double of actual electric current and voltage. This factor called Power factor of circuit(abbreviated. P.F)
• Lumen Lumen is the measured value for light from light source in all-direction which is the index indicating the total light from actual light source. Lumen is the visible light by human in wide electromagnetic wave. High lumen means more bright light source. 1 lumen is almost same brightness as that of 1 candle.
