Many people work during the day and can fit in a nighttime stroll. CONTOURED The gentle curve of the luminaire evenly spreads light over a wide area, while minimizing glare BREEZY Branching form maximizes airflow, keeping the powerful LEDs cool.

A software-optimized aspheric profile combined with precision facets provides narrow and medium beam patterns with homogeneous central spots and useful peripheral spilled light. The high collection efficiency reaches 88% of the total flux emitted from the LED. Three locating legs assure proper relative placement between the reflector and the OSTARTM LED. Typical applications are: • Portable lighting (flashlights, bicycle, etc.) • Architectural Lighting • Most application requiring a bright central spot with peripheral spilled light.
