Testing
Each of our finely manufactured bulbs are tested in our in-house quality lab, which is equipped with international level of testing mechanism like humidity test, life test etc. Apart from in-house checks, we also conduct timely testing of the bulb quality from the external agency. This leads to zero defects and makes our bulb fare highest in quality. We conduct 100% inspection of the raw material before processing them on production floor, and same level of rigorous check takes place while production also. Each bulb is quality tested by the engineers before going for final packing.
Photometry
Photometric globe is used to check all the electrical parameters of the bulb such as voltage, wattage, current, lumens and color temperature (CCT)

Luminous flux Φ
Unit: Lumen [lm]
Luminous flux is the term used to represent the quantity of energy of the light emitted per second in all directions.
Light Output ŋ
Unit: Lumen per Watt (lm/W)
The amount of light that falls on a surface is measured in lux. One lux is the light that obtained from a light source of one lumen over an area of one square meter.
Color Temperature
This is measured in degrees Kelvin that indicates the color of a specific type of light source. (Kelvin is indicated by the unit symbol K.) Color temperatures over 4000K are called cool white colors while lower color temperatures (2700~3000K) are called warm white colors (yellowish white). The higher the temperature of a light source, the greater the portion of blue and lower the proportion of red in the color spectrum.
