LED-Old Town Luminaire Square with LED Insert Metis
Back to OverviewModell412
Due to their nostalgic design, BöSha old town luminaires are perfect for the efficient illumination of historical old town areas. By combining the latest LED and reflector technology as well as additional control functions they provide an economic efficiency previously not attained.
This luminaire primarily creates lighting accents in historical old towns and alleys, fashions squares and parks and impresses by pleasant, glare-free light. Diverse roof variants allow for creative scope.
The LED insert "Metis" displays a pleasant, wide-beam lighting character. By means of segmental assembly partial areas, where less light is wanted (e. g. near house walls), can be shaded.
Having an optimised luminous intensity distribution, the quantity of luminaires can be reduced due to larger luminaire spacing. The luminaires are equipped with highly efficient multi-chip-on-board LED technology - supplying nominally 120 lm/W at 5,000 K. A service life of more than 100,000 hours is ensured.
Recommended pole height: 3 - 5 metres
