Tubular
Bulbous tubular
Reflector
Ellipsoidal

The correct answer is: Bulbous tubular

The BT56 lamp is characterized by its bulbous tubular shape, which is specifically designed for certain applications in lighting. The "BT" designation stands for "Bulbous Tubular," indicating that the lamp has a rounded, bulbous end combined with a tubular body. This shape allows for efficient light distribution and can accommodate various lighting fixtures without sacrificing performance. Understanding lamp shapes is crucial for lighting technicians, as it directly affects compatibility with fixtures and the quality of illumination. The bulbous end provides a larger surface area for light emission, while the tubular portion facilitates installation in standard fixtures that utilize this lamp type.
