The LEDVANCE OSRAM DECOSTAR 51 PRO SP 48860 20W/12V/10°/GU5.3 is a halogen spotlight designed for applications where brilliant, focused accent lighting is required. Its 10° spot beam angle concentrates light tightly on a subject, making it effective for display cases, dining tables, mirrors, and kitchen work surfaces.

Built with IRC (infrared coating) technology and a decorative cover, this lamp maintains consistent luminous intensity and stable colour rendering throughout its rated service life, a key advantage over standard halogen lamps of equivalent wattage.

Key Features

• 10° spot beam angle for tight, focused illumination
• GU5.3 bi-pin base, 20 W, 12 V
