Ushio QIH120-500/S

is a 500 W, 120 V quartz infrared heater lamp designed for fast, controlled radiant heating in compatible equipment. Its clear quartz construction provides concentrated infrared output across a 127 mm (5.00 in.) lighted length. The lamp features metal-sleeve ends with lead-wire connections and a 5,000-hour average rated life.

Applications

Paint and Ink Drying

Provides rapid radiant heating for compatible drying systems used with paints, inks, coatings, and related production processes.

Graphic Arts and Printing

Suitable for compatible printing and graphic arts equipment where infrared energy is used to accelerate drying and process heating.

Semiconductor Processing

Supports semiconductor equipment requiring localized infrared heating, rapid response, and controlled thermal processing.

Scientific and Medical Equipment

Provides controlled radiant heat for compatible laboratory, scientific, and medical equipment requiring reliable infrared output.

Features

• Fast-response infrared output supports rapid heating and process adjustment
• Direct radiant heating concentrates energy on the target without relying primarily on heated air
• Non-contact heating supports controlled processing without physical contact with the workpiece
• Linear lamp design distributes radiant energy across a defined heating area
• Clear quartz construction supports efficient transmission of infrared radiation
• Metal-sleeve ends with lead wires support integration into compatible OEM equipment

Specifications

FAQs

What is the difference between clear and translucent quartz infrared lamps?

Clear quartz allows more visible light to pass through the lamp envelope, while translucent quartz diffuses more visible light. Both configurations transmit infrared energy for heating, but the correct lamp type should be matched to the original equipment specification.

How does quartz infrared heating differ from convection heating?

Quartz infrared heating transfers radiant energy directly toward the target rather than relying primarily on heated air, allowing faster response and more localized heating than many convection-based methods.

Can a physically similar infrared lamp be used as a replacement?

Not necessarily. Replacement lamps should match the required voltage, wattage, overall length, lighted length, quartz type, end configuration, burning position, and other specifications required by the equipment manufacturer.

What safety precautions should be followed when using this infrared lamp?

Infrared lamps operate at very high temperatures and can present burn, eye, fire, electrical, and breakage hazards. Do not look directly at the operating lamp or touch it until it has fully cooled. Keep combustible materials away from the heating area and disconnect electrical power before installation, removal, cleaning, or servicing. Handle the quartz envelope with clean gloves or a lint-free cloth and avoid touching it with bare fingers. Always use the lamp in properly rated equipment and follow the equipment manufacturer's installation and safety procedures.
