Mercury Vapor 100W Lamp

The Ushio USH-102DH is a 100-watt mercury vapor discharge lamp producing 2500 lumens. It suits projection or specialist lighting fixtures that require this specific burner type. Buyers needing higher lumen output or longer service intervals should consider alternative lamp technologies.

Sustained Output Stability

Rated life is 200 hours under standard operating conditions. Light output and colour consistency are maintained across this period when the lamp runs at its designed 100 watts. Frequent striking cycles or inadequate cooling will reduce the achievable runtime below the rated figure.

Fixture And Power Constraints

The lamp must be operated on a compatible mercury vapor ballast matched to 100 watts; direct mains connection will destroy the burner. Enclosed fixtures require adequate ventilation to prevent envelope overheating. Buyers without a verified ballast and fixture combination cannot use this lamp safely.

Questions about this item

How much heat and power does the 100 W mercury-vapor bulb produce when running continuously?

The lamp draws 100 W and has a rated life of 200 hours, so it will generate typical HID heat levels during extended use.

What fixture and ballast are required to operate the USH-102DH bulb?

It requires a fixture that accepts a high-intensity discharge lamp and a ballast specifically rated for 100 W mercury-vapor operation.

Will the 2500-lumen output work alongside older lower-wattage mercury-vapor lamps in the same circuit?

Each 100 W lamp needs its own dedicated ballast; mixing wattages on one ballast is not supported.
