The Quantum Photo-Meter L (Digital Lux Meter) is used for lighting surveys by architects, designers, or industrial engineers to determine lighting design efficiency. It quickly compares ambient illumination to, for example, video screen brightness to determine suitability of the visual environment. Scene lighting of sets can be measured and adjusted for uniform illumination. Other applications suited to the pocket Photo-Meter LX are stage lighting design, green house surveys, measurement of illuminated signs, lamp manufacturers' testing, and more.
Quantum Photo-Meters 1, 2 and Lux Meter are precision digital meters for laboratory, scientific and industrial use, as well as for video and cinematographic applications wherever accurate footcandle, footlambert or lux measurements are called for. The switch from footcandle or footlambert calibration is accomplished in seconds.
Note: Luminance measurements with PhotoMeter E and L are possible with optional Luminance Receptor PM-13. Must be calibrated to individual meter. Quantum recommends ordering accessories at the same time meters are ordered. Otherwise, it will be necessary to return meters to the factory for calibration.
