The Osram Powerstar HQI-BT is a high-performance 400W metal halide lamp with an E40 base for industrial, warehouse, and sports lighting. It produces a luminous flux of 34,000 lumens with a daylight-style 5500K color temperature — suitable for applications where bright and natural light is required. Requires an external ballast (HID choke) and igniter.

Compatibility and installation

Applications: industrial halls, warehouses, sports halls, construction sites, large-area outdoor lighting. The high luminous flux and 5500K daylight color are suitable for locations requiring precise visual work or high light output over large areas.

Ballast: this lamp requires a separate HID ballast (magnetic choke or electronic HID-EVG) and an igniter. The lamp voltage is 115V, provided via the ballast. Never connect the lamp directly to 230V mains voltage.

Start-up time: the lamp reaches full power in approximately 2–4 minutes, and if the lamp is switched off, it requires 5–15 minutes to cool down before it can be re-ignited.

Installation checklist:

  1. Use only in HID-compatible luminaires with a 400W magnetic choke or electronic HID-EVG.
  2. Allow the lamp to cool completely before replacement — the operating temperature exceeds 300 °C.
  3. Do not touch the glass part of the lamp with bare hands — fingerprints can cause the glass to crack when heated.
  4. Always have the installation performed by a qualified electrician.
  5. See the warranty terms of our partners.

Usein kysytyt kysymykset

What is this lamp intended for?

The lamp is suitable for lighting industrial and sports halls as well as large warehouses and outdoor spaces. A luminous flux of 34,000 lm with a daylight-like 5500K color is sufficient to cover a large surface area, and a CRI of 80+ ensures good color rendering for work requiring precision.

Can the lamp be connected directly to 230V mains voltage?

No. The lamp voltage is 115V, and it requires a separate HID ballast (magnetic choke or electronic HID ballast) and an ignitor. Direct connection to 230V will destroy the lamp immediately. Use only in an HID-compatible luminaire.

Why doesn't the lamp turn back on immediately after switching off?

Metal halide lamps require 5–15 minutes to cool down before they can reignite. When hot, the arc-carrying metal vapor inside the lamp is so dense that reignition would require a peak voltage from the ballast. A cooled lamp ignites normally and reaches full power in 2–4 minutes.

Is an LED option available?

Yes. LED technology has almost completely replaced metal-halide lamps in new installations — the same luminous flux (34,000 lm) can be achieved with an LED high-bay luminaire at approximately 250–300 watts (vs. 400W + ballast losses). We recommend contacting our customer service to ask about an LED alternative if it is a new installation or a major renovation. As a replacement lamp, this Powerstar HQI-BT is suitable for sites where there is no desire to replace the existing luminaire.
