Product Overview
Sylvania AR111 lamps combine a UV-filter capsule with an axial filament set into a precisely engineered aluminum reflector, giving a controlled 8° spot distribution at 20,000 CBCP. The aluminum reflector construction is built for accurate, repeatable beam control in display and accent applications where beam consistency matters.
This 12V, 50W lamp uses a Push Screw Terminal base and is rated for 3,000 hours of average life at 3000K. Because it runs on 12V, it requires a compatible low-voltage transformer or electronic driver rather than a direct line-voltage connection.
