Large Strobe U-Shaped Tube Head A professional-grade large light with a U-shaped flash tube. While its luminous efficiency and light output are lower than C-shaped tubes, it is closer to a point light source, making it suitable for portraits and product photography where sharp shadows are desired. Point Light Source Characteristics: The U-shaped flash tube emits light from a specific central point. When combined with accessories like grids or spotlights, it creates sharp contrast. Suitable Photography: Ideal for dramatic portraits requiring clear shadows, product photography where edges need emphasis, and situations where a hard light is used to express texture. Compatible with Photona and Sunstar strobe generators. The tube is clean and not dirty. It has been used infrequently. The flash duration is shorter compared to C-shaped tubes. - Type: Strobe - Cable Length: Approx. 2 meters - Bulb Type: Halogen Bulb - Reflector: Silver Reflector - Connector Type: 6-pin connector Thank you for looking.
