Sphere Daylight HMI Lighting Balloon – 16kW, Ø5.7m Professional-Grade Skylight Simulation for Cinematic Production
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.
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 – Provides 360° even illumination that mimics natural skylight, ideal for wide shots and multi-camera setups.
- Professional-Grade Lamp Integration – Features four robust G38 lamp holders with thermal protection, compatible with ARRI or Power Gems electronic ballasts for stable, flicker-free operation.
- High Output & Natural Light Quality – 1,440,000 lumens of 5600K daylight with >90 CRI for realistic outdoor simulation.
- Versatile Deployment – Supports helium lift for aerial use or ground-based rigging.
- Durable Construction – Hydrolysis-resistant, anti-UV nylon fabric with high helium retention, suitable for challenging environments.
- Rapid Warm-Up – Achieves full output in under 3 minutes.

Applications
Feature Films – Simulating overcast daylight in open fields, replacing multiple HMIs with one seamless source.
Historical Epics – Illuminating castle courtyards or battle scenes with massive coverage and minimal rigging footprint.
Automotive Advertising – Exterior car shoots under “cloudy” conditions, eliminating specular highlights while preserving detail.
Studio Backlot – Permanent daylight fill for outdoor sets, capable of remaining inflated for weeks with proper anchoring.
Product Advantages
Power & Performance – High-output HMI technology delivers daylight color accuracy unmatched by LED alternatives at this scale.
Durability & Deployment – Fabric treated for UV and hydrolysis resistance; includes reinforced lifting points and anchor loops for secure installation.
Support & Compatibility – Fully compatible with industry-standard ballast systems; global shipping with optional on-site technician support.
