Gigahertz - Model MSC15 - Compact and Handheld Spectral Light Meter Brochure

LEDs enable much greater control of the lighting quality than the technologies they are rapidly replacing. Many international standards now specify requirements for internal and external lighting systems in terms of both ‘quality’ and ‘quantity’ of light as well as in terms of efficiency and life time. Photometry in the lighting industry generally focuses on the intensity (i.e. illuminance) and color (i.e. correlated color temperature CCT and color rendering index CRI) of light falling on a surface. LED lamps are extremely versatile in terms of emission spectra, which is why spectral measurement of the illuminance and color has now become essential for any high-end light meters.
