Dark Sky returns darkness to the night
The luminaires from our “Dark Sky” series direct their light with high efficiency onto the illuminated area, and emit less than 1% of their luminous flux into the upper half-space of the luminaire.
The exact data regarding luminaire luminous flux in the upper half-space as well as information on the BUG rating according to IES TM-15-07 and the CEN Flux Code according to EN 13032-2 can be found in the product data sheets for the individual luminaires on the BEGA website and must be checked against the respective regionally applicable regulations.
BUG rating in compliance with IES TM‑15‑07
The system for luminaire testing with photometric data refers to measurement of light incidence:
Backlight – Light behind the luminaire Uplight – Light above the luminaire Glare
The measured lumen values are represented on a scale from 0 (low) to 5 (high). These values must be checked against relevantly applicable regulations.
CEN Flux Code according to EN 13032‑2
Percentage of the luminous flux of the luminaire emitted upward and downward in specific solid angles. Each segment has an assigned number.
