Product Overview

The Osram Halostar Frosted series is the professional choice for glare-free accent lighting. The frosted coating on the T3 bulb envelope scatters light evenly, making it particularly effective in fixtures with visible bulbs or shallow shades. This 12V capsule is fully dimmable, allowing for seamless control of the ambiance in hospitality or residential settings. It is approved for use in open luminaires (to IEC 60598-1) and contains no mercury, ensuring it is both safe to use and easy to dispose of with standard household waste. Its robust design and reliable performance make it a staple for high-quality under-cabinet "puck" lights and specialized landscape spotlights.
