Sphere Daylight HMI Lighting Balloon – 16kW, Ø5.7m for High-Output Cinematic Skylight Simulation
The Artemis Sphere Daylight HMI lighting balloon is engineered for large-scale film and television productions requiring massive, natural-looking daylight illumination. Equipped with four 4000W Osram HMI lamps (5600K), this 75m³ spherical diffuser delivers an impressive 1,440,000 lumens of flicker-free, ultra-soft light—ideal for simulating overcast sky conditions, exterior fill, or studio backdrops without harsh shadows.
Unmatched Scale and Softness for Epic Productions
With a diameter of 5.7 meters, the Artemis Sphere creates one of the largest single-source soft lights available in the industry. Its spherical geometry ensures omnidirectional diffusion, wrapping light evenly around subjects—perfect for night-for-day scenes, period dramas, or automotive shoots where realistic ambient bounce is critical. The unit can be deployed via helium lift for aerial positioning or mounted on ground-based rigging systems using standard grip hardware.

Key Features
True Spherical Diffusion
Unlike flat or elliptical sources, the perfect sphere shape eliminates directional bias, providing 360° even illumination that mimics natural skylight—critical for wide shots and multi-camera setups.
Professional-Grade Lamp Integration
Features four robust G38 lamp holders with thermal protection and secure locking mechanisms, compatible with industry-standard ARRI or Power Gems electronic ballasts for stable, flicker-free operation at any frame rate.
Applications
| Industry | Use Case | Benefit |
|---|
| Feature Films | Simulating overcast daylight in open fields | Replaces multiple HMIs with one seamless source |
| Historical Epics | Illuminating castle courtyards or battle scenes | Massive coverage with minimal rigging footprint |
| Automotive Advertising | Exterior car shoot under “cloudy” conditions | Eliminates specular highlights while preserving detail |
| Studio Backlot | Permanent daylight fill for outdoor sets | Can remain inflated for weeks with proper anchoring |
