Tube Tungsten Lighting Balloon – 20kW, Ø3.2m × 8m for Linear Soft Fill in Film & Television
The Artemis Tube Tungsten lighting balloon delivers 540,000 lumens of warm, continuous, and ultra-soft illumination from an elongated 65m³ diffuser. Equipped with four 5000W tungsten lamps (3200K), this 8-meter-long cylindrical source is engineered for scenarios requiring long-axis, shadowless fill—such as interior corridors, aircraft cabins, night street scenes, or period drama interiors where authentic incandescent ambiance is essential.
Precision Linear Illumination for Complex Environments
Unlike spherical or elliptical balloons, the tube design provides directional soft light along its entire 8-meter length, minimizing spill while maximizing coverage in narrow or linear spaces. The high-CRI (>98) tungsten output ensures perfect skin tone rendering and seamless integration with practical lamps on set—ideal for close-ups, dialogue scenes, or mixed-light environments where color fidelity is non-negotiable.

Key Features
Optimized Internal Lamp Arrangement
Four 5kW tungsten lamps are evenly spaced along the central axis with reflective baffles to ensure uniform diffusion from end to end—eliminating hotspots and maintaining consistent intensity across the full 8-meter span.
Thermal Management & Safety
Features dual-layer fabric with an inner heat-reflective barrier that protects the outer diffusion layer from degradation, extending service life even during extended 12+ hour shoots under full load.
Applications
| Industry | Use Case | Benefit |
|---|
| Feature Films | Night interior of a moving train or subway car | Provides continuous ambient without visible fixtures |
| TV Series | Hospital hallway or hotel corridor scenes | Eliminates multiple stand-mounted lights |
| Aviation Commercials | First-class cabin illumination | Matches existing cabin tungsten LEDs perfectly |
| Period Dramas | 1940s–1970s interior with practical lamps | Seamless spectral match with vintage bulbs |
