LED Round Luminaire with Skylight - with Umbrella Roof

Back to Overview

Model 603

Product Description and Application
BöSha round luminaires interpret the classical shape of the round luminaire in a new, contemporary way. Consequently, a light, transparent luminaire without external struts was created, combining timeless design with the latest LED technology. Not only does it impress with its unsurpassed energy efficiency, its needs-based light distribution and control but also with its sturdiness and durability.
Various roof shapes, pleasant light colours, possibilities of dimming and night-time dimming as well as segmental assembly for partial shading of house fronts ensure high acceptance. Optionally, a skylight provides additional decorative aspects.
The sober and reserved shape can be integrated anywhere, creates an attractive cityscape and upgrades squares and parks, prestigious city areas, residential and collecting roads. Furthermore, the round luminaires are suited for outdoor grounds of administrative buildings, hospitals and schools.
Pay attention to the quality and efficacy of the product. 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 LED modules - supplying nominally 120 lm/W at 5,000 K.


Recommended pole height: 3 - 5 metres
