The LEDVANCE OSRAM DECOSTAR 51 PRO FL 48860 20W/12V/24°/GU5.3 is a halogen floodlight lamp that combines IRC energy-saving technology with a 24° flood beam, suitable for broader area illumination in kitchen, dining, retail, and workplace settings. Its decorative cover gives a clean finish in open-face luminaires.

Like the PRO SP variant, this lamp maintains consistent luminous intensity and a stable colour location throughout its rated life, avoiding the gradual dimming and colour shift that affects standard halogen types.

Key Features

• 24° flood beam angle for broader area illumination
• GU5.3 bi-pin base, 20 W, 12 V
• IRC (infrared coating) technology for improved energy efficiency
• Decorative cover (Deco cover) included
• Ultraviolet filter
• Mercury-free; approved for open luminaires per IEC 60598-1
