The Norman Lamps Q20DC is a 20W single-ended T4 halogen bulb designed for reliable performance in line-voltage fixtures operating at 130V. Built around the BA15D double contact bayonet base, this compact halogen lamp measures 2.30 inches in length and 0.52 inches in diameter, making it well suited for space-constrained fixture housings where a precise physical fit is essential. The clear glass envelope delivers a warm white halogen glow with near-perfect color rendering, faithfully reproducing the true colors of illuminated subjects. As a single-ended halogen type, the Q20DC supports multiple filament configurations, contributing to stable light output and consistent performance throughout its rated 2000 life hours. The lamp is fully dimmable, allowing smooth brightness adjustment when paired with a compatible dimmer control. With a 130V rating, this halogen bulb is optimized to run efficiently on standard North American line voltage, and the elevated voltage rating also provides a useful operating margin that supports extended lamp life under normal service conditions. The Q20DC is appropriate for display cases, accent lighting, specialty fixture applications, and any installation requiring a compact, bright, clear-glass halogen source in a BA15D socket.
