Product Overview

The Osram Halostar Starlite represents the pinnacle of compact halogen technology. Its axial filament ensures that light is projected evenly, maximizing the effectiveness of fixture reflectors in low-voltage systems. Unlike standard capsules, the Starlite is built with UV-filter technology to prevent the yellowing of fixture components and the fading of illuminated objects. With a perfect 100 CRI, this lamp renders colors with absolute fidelity, ensuring that retail displays, artwork, and interior finishes look their best. Its incredibly small footprint allows for sleek, minimalist luminaire designs without sacrificing brightness or dimming capabilities.
