OSRAM DECOSTAR® 51S | 35W 12V | MR16 Spot 10° Dichroic Reflector

The Osram Decostar 51S (ANSI FRB) is a professional-grade 35W low-voltage halogen reflector lamp designed for precision accent lighting. Engineered with a dichroic reflector, this lamp effectively manages thermal output by directing most of the heat through the rear of the reflector, reducing heat in the light beam by up to 66%. This makes it the ideal choice for illuminating heat-sensitive objects in retail displays, galleries, and hospitality settings. Featuring a tight 10° spot beam spread, a crisp 3000K color temperature, and a protective clear cover glass, it delivers a concentrated, brilliant light that enhances textures and colors with a perfect CRI of 100.
