    Sylvania HSI-T 1000W/4K – tubular clear metal halide lamp for E40 sockets: 1000 W, 80,000 lm, neutral white light. Operates on a standard 1000 W mercury ballast with an external ignitor, enclosed luminaires only.

  • Product description

    Metal halide lamp | E40 | 1000W | 4K | 80000 lm | tubular | 230V | Sylvania HSI-T | 5410288205953

    Sylvania HSI-T 1000W/4K is a tubular, clear 1000 W metal halide lamp with an E40 base and quartz arc tube. It is intended for logistics, industrial and outdoor sites – warehouses, stadiums, car parks, rail and dock yards. The lamp operates on a standard 1000 W mercury lamp ballast with an external ignitor on a 230 V supply.

    Key point:
    This is a replacement lamp for existing 1000 W metal halide luminaires and floodlights. Because it runs on a standard mercury lamp ballast, it fits most existing 1000 W installations – only the lamp is replaced, not the luminaire. Neutral white 4K light renders colours much better than the yellow light of sodium lamps.

    Operating principle

    The lamp is screwed into an E40 socket in an enclosed luminaire with a 1000 W ballast (standard mercury lamp type) and an external ignitor. When switched on, the ignitor strikes the arc in the quartz arc tube with a high-voltage pulse, and the ballast limits the current to the operating value of 8.25 A.

    After ignition, the lamp warms up for several minutes before reaching full luminous flux. A hot lamp that has been switched off will not restrike immediately – it must cool down first. This makes it suitable for long operating periods rather than frequent switching.

    The result is 80,000 lm (approx. 80 lm/W) of neutral white light from a single point. The manufacturer states an average life of 10,000 h.

    Why choose Sylvania HSI-T 1000W/4K?
    It restores existing 1000 W lighting for the price of a lamp, without replacing luminaires, ballasts or cables. It also suits installations with mercury lamp gear – an external ignitor is enough.

    Key features

    • 80,000 lm from one source – a single luminaire lights a large area, with fewer points on ceilings or masts.
    • Neutral white 4K light – colours are distinguished much better than under sodium lamps.
    • Runs on a mercury lamp ballast – fits most existing 1000 W installations, only an external ignitor is needed.
    • E40 base, tubular shape – standard format for 1000 W floodlights and industrial luminaires.
    • 10,000 h average life – less frequent replacement in high-mounted luminaires.
    • Clear bulb – precise beam control by the reflector, especially in floodlights.

    Where is it used?

    • High-bay logistics centres and warehouses
    • Industrial halls and hangars
    • Stadiums and large sports grounds
    • Outdoor car parks
    • Rail yards and port areas
    • Loading yards and construction sites
    • Floodlighting of large areas

    Use by need

    For warehouse or logistics facility managers.
    Quickly restores failed lighting in existing luminaires without waiting for a refurbishment project.
    For port, terminal or yard operators.
    Keeps outdoor areas lit with even white light where recognising colours and markings matters.
    For electricians / maintenance companies.
    A standard E40 1000 W MH lamp for stock – fits most existing 1000 W floodlights with mercury-type ballasts.

    Practical application

    If a loading yard has 1000 W floodlights and some of them no longer ignite or glow pinkish, check that the ballast is 1000 W (8.25 A) and that the luminaire has an external ignitor. If so, replace the lamps with Sylvania HSI-T 1000W/4K – ideally all lamps in one zone at once, so that the light colour stays uniform.

    Advantages

    • High luminous flux – 80,000 lm from a single point.
    • Neutral white light – 4K, good colour discrimination.
    • Wide compatibility – runs on a standard mercury lamp ballast.
    • Long life – 10,000 h on average.
    • Replacement without refurbishment – much cheaper than replacing the luminaire with LED.

    Disadvantages / limitations

    • Does not work without a ballast and external ignitor – not for direct 230 V connection
    • Takes several minutes to warm up and will not restrike hot – unsuitable for frequent switching or motion sensors
    • The manufacturer has discontinued this model – quantities are limited and the same lamp may not be available later
    • Energy class G, efficacy ~80 lm/W – LED solutions are more economical
    • Luminous flux cannot be dimmed

    Safety and installation notes

    • Before replacing the lamp, disconnect the power and let the lamp and luminaire cool down – the bulb operating temperature is very high.
    • Use only in an enclosed luminaire with an intact protective glass.
    • Do not touch the bulb with bare hands – use gloves or a clean cloth.
    • In a mercury lamp luminaire, an external ignitor must be installed – without it the lamp will not ignite.
    • Do not fit the lamp in sodium (SON) lamp gear unless the luminaire manufacturer specifies it.
    • If the lamp breaks, follow the manufacturer cleaning instructions – the lamp contains 72.5 mg of mercury; dispose of used lamps as hazardous waste.

    Quick selection guide

    Suitable when you need:
    • to replace a 1000 W metal halide lamp in an existing luminaire
    • white light in warehouses, stadiums or outdoor areas
    • spare lamps for a maintained site
    Check before use:
    • that the ballast is 1000 W, 8.25 A (mercury lamp type)
    • that the luminaire has an external ignitor
    • that a Ø 66 × 382 mm lamp fits and the luminaire is enclosed
    Important reminder: this lamp does not replace the ballast or ignitor – if the gear is faulty, a new lamp will not ignite or will fail quickly.

    FAQ

    Can the lamp be connected directly to a 230 V outlet?
    No – it only works via a 1000 W ballast and an external ignitor.
    Can it replace an HPL-N 1000W mercury lamp?
    Yes, the ballast is suitable, but an external ignitor must be installed in the luminaire.
    Can it replace a SON-T 1000W sodium lamp?
    Only if the luminaire gear is suitable for metal halide lamps – a sodium ballast and ignitor are not suitable for this lamp.
    Why is the lamp dim right after switching on?
    A metal halide lamp reaches full luminous flux only after warming up for several minutes.
    Why does the lamp not restart immediately after switching off?
    A standard ignitor cannot restrike a hot lamp – wait until it cools down.
    Can it be used in an open luminaire?
    No – the manufacturer permits use only in enclosed luminaires.
