Medium-power 800W HMI fixture offering versatile coverage. A solid compromise between output intensity and ease of handling on set.
Definition
The 800W HMI is a daylight fixture for film productions with 800 watts of power and a 5600K color temperature. HMI lamps produce daylight-like light with high luminous efficacy through mercury-metal halide discharge.
Practical Application
Areas of use for the 800W HMI:
- Daylight Matching: Balancing window light in interiors
- Fill Light: Fill-light for outdoor shots in sunlight
- Subject Illumination: Key light for smaller sets and interviews
- Background Light: Separation of subject and background
Technical Details
Technical specifications:
- Power consumption: 800W with electronic ballast
- Luminous efficacy: approx. 85 lm/W (significantly higher than Tungsten)
- Burn time: 400-750 hours depending on manufacturer
- Start-up time: 2-3 minutes to full brightness
Practical Tips
- Electronic ballast (EVG) with 25 kHz prevents flicker at 25p/50i
- Change lamp only with gloves - fingerprints shorten lifespan
- Allow 10 minutes cooling time after switching off before switching on again
- CTB filter for 3200K matching reduces light output by 1.5 stops
Professional Standards
Standards in film production:
- Flicker-free operation through high-frequency ballasts from 25 kHz
- Color Rendering Index (CRI) above 90 for natural skin tones
- Consistent color temperature throughout the burner's lifespan
- Safe cabling with separate circuits for high power
