Ushio QIH120-500/L

is a 500 W, 120 V quartz infrared heater lamp designed for fast, controlled radiant heating. Its clear quartz construction provides concentrated infrared output across a 127 mm (5.00 in.) lighted length. The lamp features round ceramic ends with lead-wire connections and a 5,000-hour average rated life. This model is sold in cases of 20 lamps.

Applications

Semiconductor Processing

Provides rapid, controllable infrared heating for compatible semiconductor processing equipment where localized heating and precise thermal control are required.

Laboratory and Scientific Heating

Suitable for laboratory and scientific equipment requiring concentrated, non-contact radiant heat with fast response and repeatable thermal output.

Medical Equipment

Supports compatible medical and warming systems that use controlled infrared energy for specialized heating applications.

OEM Infrared Heating Systems

Designed for compatible OEM equipment requiring a 120 V, 500 W linear quartz infrared lamp with matching dimensions, lead-wire connections, and operating requirements.

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
• Round ceramic ends with lead wires support integration into compatible OEM equipment

Specifications

FAQs

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. This supports 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, 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.
