OSRAM HALOSPOT 48 | 20W 12V | GY4 Spot 8° Halogen Aluminum Reflector

The Osram Halospot 48 (41900 SP) is a high-performance 20-watt halogen reflector lamp designed for precision accent lighting. Operating at 12V, this lamp features a unique 48mm aluminum reflector that provides excellent heat management by directing thermal output forward along with the light beam. With a tight 8° spot beam spread and a luminous intensity of 3100 cd, it is ideal for highlighting specific architectural details or retail merchandise. The GY4 bi-pin base ensures a secure fit in specialized low-voltage fixtures, while the integrated UV filter protects sensitive objects from fading and discoloration.

Brilliant Precision & Heat Management

The Halospot 48 stands out due to its all-aluminum reflector technology. Unlike dichroic reflectors that send heat backward into the fixture, the Halospot's aluminum coating reflects both light and heat forward, protecting fixture components and wiring from thermal stress. This makes it particularly suitable for recessed ceiling lights and modern track systems. With a perfect CRI of 100, it ensures that colors appear vibrant and natural, making it a favorite for galleries, museums, and high-end boutiques.

• Focused Accentuation: Tight 8-degree beam spread for high-contrast lighting effects.
• UV-Filter Technology: Integrated shielding reduces the risk of fading for light-sensitive materials.
• Superior Thermal Control: Aluminum reflector directs heat away from the lamp base and fixture.
• Fully Dimmable: Allows for total control over ambiance and lighting levels.
