OSRAM DECOSTAR® 51S | 50W 12V | EXN 36° WFL GU5.3 Dichroic MR16 Lamp

The Osram Decostar 51S (EXN) is a professional-grade low-voltage halogen reflector lamp designed for brilliant accent lighting and heat-sensitive displays. Featuring a dichroic reflector, this lamp effectively manages thermal output by emitting up to 66% of produced heat through the rear of the reflector, ensuring the light beam remains cool. With a 36° Wide Flood (WFL) beam spread and an axial filament for precise beam control, it provides a vivid 2950K warm white light. The integrated clear cover glass protects the burner while the UV-filter prevents the fading of illuminated objects, making it the ideal choice for retail galleries, museums, and high-end residential interiors.

Advanced Cool-Beam Technology

Professional lighting requires more than just brightness; it requires heat management. The Decostar 51S utilizes a specialized dichroic coating on the glass reflector that allows infrared radiation (heat) to pass through the back of the lamp while reflecting visible light forward. This reduces the heat stress on sensitive items like jewelry, artworks, or textiles. Additionally, the lamp features a UV-filter and axial filament technology, which ensures a uniform light distribution without "hot spots," delivering a perfect CRI of 100 for absolute color fidelity.

• Brilliant Accentuation: High-intensity light for focal points and architectural details.
• Heat Management: Dichroic reflector reduces heat in the light beam by up to 66%.
• UV Protection: Integrated filter protects sensitive materials against discoloration.
• Fully Dimmable: Allows for total control over atmosphere and mood in any setting.
