Product Overview

The Ushio 1001298 QIH120-500T/S is a precision quartz infrared heater lamp engineered for industrial heating applications requiring instant on/off response and precise heat control. Ushio's QIH series provides clean, instantaneous infrared heat output — making these lamps ideal for radiant applications involving heat-sensitive materials that cannot tolerate sustained exposure to a heat source between cycles.

The double-ended T3 quartz tube construction with metal sleeve terminations and lead wires at each end allows direct integration into industrial heating equipment, conveyor systems, curing ovens, and specialty process machinery. The 2500K color temperature and high-efficiency quartz envelope enable large amounts of heat transfer with precision wattage density control — suited for high-speed production processes requiring even, controlled heat zones.

This lamp also supports focused beam optical applications. Approved enclosed fixture use only — confirm your equipment is designed and rated for this lamp before ordering.

Compatible Applications

Industrial process heating — Conveyor heating systems, curing ovens, drying equipment, and high-speed production processes requiring instant on/off IR heat control.
Heat-sensitive material processing — Applications where materials must not linger in a heat source — quartz IR provides instantaneous response with no warm-up lag.
Focused beam optical applications — Equipment requiring directed infrared output for optical or sensing purposes.
Replacement in approved enclosed IR fixtures — Direct replacement for QIH120-500T/S or QH500T3 designated lamps in compatible 120V equipment.

Before Ordering — Verify

Voltage: Confirm equipment is rated for 120V operation.
Wattage: Confirm equipment is rated for 500W.
Lamp Description: Confirm existing lamp matches QIH120-500T/S or alternate designation QH500T3.
Dimensions: Confirm 223mm MOL, 127mm light length, and 10mm diameter fit within your equipment's lamp housing.
Fixture Type: This lamp must be used only in approved enclosed halogen/IR fixtures. Confirm your equipment is rated for this lamp type.

Safety and Handling Guidelines

Approved Enclosed Fixtures Only: This lamp must be installed in approved enclosed IR fixtures. Do not operate in open or unapproved equipment.
Do not touch the quartz envelope with bare hands. Skin oils cause hot spots that can lead to premature failure or lamp burst. Use clean gloves or a lint-free cloth. If accidentally touched, clean with isopropyl alcohol before use.
Allow Cooling: Allow the lamp and equipment to cool fully before handling or replacement. Quartz IR lamps operate at extremely high surface temperatures.
Correct Voltage Required: Use only in equipment rated for 120V. Incorrect voltage will cause immediate failure or drastically reduce lamp life.
Handle with Care: The quartz tube is fragile. Avoid mechanical shock during handling and installation.

Compliance

Manufactured in Japan by Ushio Inc., Tokyo, Japan.
Verify RoHS compliance status and additional certifications with the Ushio manufacturer specification sheet prior to use in regulated installations.
