NEW Osram BTH 575W 115V (Pkg of 12)
Description
Package of 12.
The Osram Sylvania BTH is a 575W, 115V T6 halogen lamp with a P28s (medium prefocus) base, commonly used in studio, theater, TV, and video lighting where consistent brightness and stable color are critical.
Built for Fresnels and Focused Beam Control
Designed for Fresnels using a P28s medium prefocus base, the BTH features a compact, segmented C13D biplane grid filament that helps produce a controlled, even beam and predictable focus. An improved base design supports better electrical contact for reliable operation in demanding production environments.
Light Output and Color Performance
This clear, single-ended T6 lamp delivers approximately 15,500 lumens at a 3250K correlated color temperature, providing the warm halogen look often preferred for stage and on-camera work. Output and color temperature are noted as similar to the HPL and GLC lamp.
