Product Overview

The Osram Decostar 51S Standard series is the go-to choice for professionals who require consistent color quality and thermal management. The axial filament placement ensures a uniform beam pattern, eliminating the "hot spots" often seen in cheaper generic alternatives. This lamp is 100% dimmable, allowing for full control over the ambiance in galleries, retail boutiques, and high-end residential spaces. Its UV-filter glass prevents the fading of delicate fabrics and artworks, while the "Closed Face" design with clear cover glass protects the burner from dust and moisture. At 12 volts, it requires a compatible electronic or magnetic transformer for operation.

Heat Protection: Dichroic coating directs heat away from the front, protecting food, art, and textiles.
Brilliant Accent: High luminous intensity (1000 cd) provides sharp, professional contrast.
Constant Color: High-quality salts in the halogen gas prevent blackening and color shift over time.
Universal Fit: Standard 51mm (2 inch) diameter fits almost all MR16 low-voltage fixtures.
