Page 2: Introduction
Lightmeter LM10 1. Introduction The Lightmeter LM10 is an innovative new development for checking the quality of light sources. For this, the parameters such as illumination intensity, flicker frequency and flicker rate are measured. Moreover, the flickering of lamp can be illustrated acoustically in audible as well as ultrasonic range via a loudspeaker. -

Lightmeter LM10 6.3. Calculation of flicker component LM10 calculates the flicker component according to the following selectible procedures: Ripple content: Φmax – Φmin ∗100% Φmax In accordance with the Standard of Building Biology Testing Methods SBM-2015. Flicker%: Φmax – Φmin ∗100 %... - Page 15 Lightmeter LM10 In case of incandescent lamps and halogen lamps, the flicker frequency is always 100 Hz and the flickering rate is from 15% to 25%. Low-volt halogen lamps with electronic power supply are an exception. Brightness of a compact fluorescent lamp (Flicker rate 31%, flicker frequency 49 Hz) Compact fluorescent lamps also known as energy-saving lamps have a flicker frequency in the range from approx.
