This information contains the losses the light- deflecting and light-shielding components of the luminaire and thus the effect the operating efficiency the luminaire. Rated output LED luminaires Initial input power luminaire (W). The measured output rises the maximum value relative to the reduction light output the LED type used. Unless otherwise specified, the values apply for ambient temperature °C. ATTENTION: The light output and luminous efficacy for built-in LED modules are higher than those the luminaires, that these cannot compared with each other. The luminaire manufacturer has specify these parameters for all their luminaires. The maximum deviation may –10% (tolerance). Rated light output LED luminaires Initial illuminance the start operation (lm). This maximum input power corresponds to the initial value with maximum light output. This takes into account the fact that minor fluctuations may occur between the individual measured values during the production period luminaire type consequence of production conditions. Constant light output If constant light output technology used, the light output luminaire remains constant over the lamp life. Note: CLO: constant light output. The operating efficiency not normally shown separately for LED -luminaires. The values are quoted rated values. Important LED key figures .73 The Lighting Handbook Light output, output and luminous efficacy The light output, output and luminous efficacy are important key parameters to describe the efficiency LED luminaires. The maximum deviation may +10% (tolerance). Luminous efficacy LED luminaires Initial value for the ratio light output to input power (lm/W)
