Precautions luminometer use
Luminometer has a filament-type light bulb called standard light bulbs is calibrated as a light source. Fluorescent lamps are widely used in general work site, such as an LED illumination measurements the wavelength of the light is different than the standard light bulbs may be different.
In such a case, measured at several luminometer (different manufacturers of different models) by taking the average value it will be necessary to devise such.
