Details on LED luminaires
One critical aspect in comparing LED luminaires of different suppliers is the comparison of luminous flux levels, as mentioned above. In the catalogues of many manufacturers, you will find details regarding the luminous flux and efficiency of individual LEDs at a junction temperature of 25 °C in the LED chip (Tj), details regarding the luminous flux levels of the LED board used at a specific Tc temperature, but also details regarding the luminous flux levels of luminaires and luminaire efficiency levels, including the power loss of ballasts and any potential loss of efficiency through lighting optics, such as lenses, reflectors or mixing chambers.
You can find more information in the brochure.
