OSRAM DECOSTAR 51 ECO | 35W 12V | MR16 10° Spot Halogen Lamp

The Osram Decostar 51 ECO is a high-efficiency halogen dichroic reflector lamp that utilizes IRC (Infra-Red Coating) technology to deliver the performance of a standard 50W MR16 while consuming only 35 watts. This ECO-range bulb features a closed-face design with a clear cover glass, providing a concentrated 10° spot beam ideal for precision accent lighting. With a 3000K warm white color temperature and a perfect CRI of 100, it ensures constant luminous intensity and superb color rendering throughout its extended 5,000-hour rated life. The UV-filter glass protects sensitive objects from fading, making it a premium choice for galleries, retail displays, and high-end residential interiors.

Key Performance Features

The Osram Decostar 51 ECO sets a benchmark for halogen efficiency. By reflecting heat back onto the filament, the IRC technology significantly reduces energy consumption (up to 30%) while maintaining a brilliant, high-quality light output. The dichroic coating on the glass reflector ensures that most of the heat is dissipated through the back of the lamp, keeping the beam cool and comfortable for highlighted objects.

• Energy Savings: Delivers 50W of brightness while using only 35W of power.
• Integrated UV-Filter: Significantly reduces the risk of UV-induced fading on fabrics and artwork.
• Closed Face Construction: Clear front glass protects the reflector from dust and ensures easy cleaning.
• Constant Light Quality: Special reflector coating prevents color shifting over the life of the bulb.
