GE MVR1000/U 1000W Metal Halide Light Bulb

The GE MVR1000/U is a 1000W quartz metal halide lamp designed for high-output, large-area illumination where a single source needs to deliver serious lumen levels from significant mounting heights. At 100,000 lumens horizontally (108,000 vertically), this is a fixture-scale light source — paired with an appropriate reflector and housing, it illuminates sports facilities, warehouses, industrial high-bays, and large commercial interiors effectively. The 4000K color temperature produces a neutral white that renders environments without the yellow cast of HPS sources or the harsh blue of 6500K lamps, and the CRI 90 rating means color accuracy is sufficient for retail, hospitality, and applications where merchandise or occupant appearance needs to look natural under artificial light.

The BT56 bulb shape fits mogul-base fixtures and supports both horizontal and vertical burning positions, which gives specifiers flexibility when selecting compatible luminaires. The 15,000-hour rated life is a practical advantage in hard-to-access installations where relamping involves lifts or significant labor. As with all probe-start metal halide sources, a correctly rated 1000W ballast is required and must be specified separately — this is a lamp, not a complete fixture. The warm-up and hot restrike characteristics are inherent to metal halide chemistry and must be factored into controls design: occupancy sensors and circuits that cycle frequently are incompatible with this source type. For installations where the lamp burns on a fixed schedule and maximum lumen output per watt is the design priority, the MVR1000/U remains a reliable specification-grade choice.
