Flags for review:
- Osram's own catalog lists two control-gear ratings under this one EAN/lamp reference: 400W (with NAV-VG gear, 37,000 lm, CRI 93, 5200K) and 350W (with HQI-VG gear, 31,000 lm, CRI 90, 5600K). Both are shown below rather than picking one silently, since the correct rating depends on which ballast/gear drives it.

Product Overview
Osram’s POWERSTAR HQI lamps are quartz metal halide lamps used across commercial, industrial, and display lighting where compact size, high lumen output, and good color rendering are required. Different HQI families (T, BT, TS, E, E/P) vary by bulb shape, base type, and intended fixture/reflector design — always match the exact family and base type to the installed fixture.

Key Features
- HQI-TS family POWERSTAR quartz metal halide construction on a Fc2 base.
- 5200K color temperature at CRI (Ra) 93.
- 12000-hour average rated life.
- Rated for two control-gear configurations (NAV-VG and HQI-VG) with different output at each.
Compatible Applications
- Commercial and industrial high-bay, floodlighting, and display fixtures rated for this HQI family and base type
- Retail and architectural accent lighting requiring high color rendering metal halide sources
- Maintenance replacement where Osram lamp reference HQI-TS 400W/D or EAN 4050300015385 is specified
Before Ordering Verify
- Exact Osram Lamp Reference: Match HQI-TS 400W/D (EAN 4050300015385) to the existing lamp label or fixture documentation.
- Base Type: Confirm the fixture socket matches a Fc2 base.
- Wattage & Control Gear: Confirm the fixture/ballast is rated for 400W and check which control gear (NAV-VG vs HQI-VG) it uses, since output differs between the two — see the alternate rating table above.
- Color Temperature: Confirm 5200K matches the existing lamps in the fixture or space.
- Burning Position: Confirm the fixture orientation matches the rated p 45 burning position.
Safety & Installation Guidelines
- Qualified Installation: Install and service only with power disconnected, following applicable electrical codes.
- UV Exposure: Use only in fixtures with adequate shielding; do not operate with a damaged or broken outer envelope.
- Correct Ballast Match: Operating this lamp on an incompatible ballast/gear type can cause premature failure, incorrect color temperature, or fixture damage.
- Disposal: Metal halide lamps contain mercury — dispose of per local regulations (www.lamprecycle.org).
- Cooling: Allow the lamp to cool fully before handling or removal.
