OSRAM HMI Digital 400W Metal Halide Bulb

The OSRAM HMI Digital 400W bulb is a high-intensity discharge lamp built for film, TV and video production. It delivers 33000 lumens at a 6000K colour temperature with a CRI above 90 for accurate colour rendition. The GZZ9.5 base fits compatible electronic ballasts used on professional lighting fixtures. This lamp suits cinematographers and lighting technicians who need flicker-free output at high frame rates.

Thermals Noise and Power Draw

The lamp operates at 400 watts and achieves up to 100 lumens per watt for efficient output. Round moly-foil construction distributes heat and current evenly to extend the 650-hour rated life. Hot-restart capability allows immediate re-ignition after a power interruption without a cool-down wait. UV-Stop quartz reduces UV emissions by up to 99.9 per cent, lowering heat load on fixtures and talent.

Bundled Accessories and Software

A reusable splash-proof carrying case is supplied to protect the lamp during transport and storage. The dimmable design works with high-speed electronic ballasts running at 1000 Hz or higher to eliminate flicker on high-speed cameras. No software or additional accessories are included beyond the protective case. Buyers needing a different colour temperature or base type should verify fixture compatibility before purchase.

Questions about this item

How do I install the OSRAM HMI Digital 400W bulb into a GZZ9.5 socket, and what step is commonly missed?

Align the pins with the GZZ9.5 socket, push firmly until seated, then verify the electronic ballast is set to 1000 Hz or higher for flicker-free operation — the hot-restart feature will not engage correctly if the ballast frequency is too low.

What maintenance or replacement will the OSRAM HMI Digital 400W bulb need after its rated life?

Replace the bulb after approximately 650 operating hours; the round moly-foil construction distributes heat evenly to reach this lifespan, and the reusable splash-proof case protects the spare during transport.

What limit appears first when the OSRAM HMI Digital 400W bulb runs continuously at full output?

The 650-hour rated life is the primary limit; sustained 400W operation at 75V with 6000K colour temperature will reach this limit before thermal or UV-stop degradation becomes critical.
