Ushio 1001297 QIH120-500T/E 500W 120V Quartz Infrared Heater Lamp - 1001297-QIH120-500T/E

Ushio 1001297 QIH120-500T/E – 500W 120V Quartz Infrared Heater Lamp

The Ushio 1001297 QIH120-500T/E is a 500W, 120V quartz infrared heater (QIH) lamp, built with translucent quartz and a r7s base (contact type). It has a Maximum Overall Length of 220.0mm and a 127mm lighted (filament) length, with 216mm contact-to-contact spacing. Rated color temperature is 2500K and average life is 6000 hours. Physically it is a straight lamp with contact-to-contact (L1) base spacing, R7s-style contact base. It cross-references to Ushio's alternate designation QH500T3/7.

Technical Specifications

Product Overview

Quartz infrared heater (QIH) lamps provide clean, instantaneous, precisely controlled radiant heat for applications such as baking, drying, curing, dehydrating, warming of foods, and general area warming. Unlike convection or forced-air heating, a QIH lamp reaches full output almost immediately and can be cycled on/off or dimmed for tight process control, without the lag of a heated air mass.

This 1001297 is rated 500W at 120V with a 220.0mm maximum overall length and a 127mm lighted length. It uses translucent quartz. The lamp terminates in a r7s base (contact type).

At a rated 6000-hour average life and 2500K color temperature, this lamp fits process heating, scientific/medical, and semiconductor applications where Ushio's QIH lamps are commonly specified for their precise, controllable, instant-on heat output.

Compatible Applications

• Industrial process heating: baking, drying, curing, dehydrating
• Food warming and general area warming
• Scientific and medical applications: infant environment warming, heat therapy, spa/sauna heating, laboratory environmental control
• Semiconductor manufacturing: precise temperature and heating-zone control

Before Ordering – Verify

• Confirm voltage matches 120V — QIH lamps are voltage-specific across this family (104V through 600V); a lamp built for one voltage is not interchangeable with another
• Confirm base type (R7s Base (Contact Type)) against the fixture/holder — the seven QIH base types (metal clip, R7s contact, metal sleeve, lead wire, round or flat ceramic) are not interchangeable
• Confirm physical fit: MOL 220.0mm, contact-to-contact 216mm against the available socket-to-socket or clip-to-clip distance in the fixture

Safety and Handling Guidelines

• Quartz infrared heater lamps generate significant heat and infrared radiation — do not touch the lamp during or immediately after operation
• De-energize the fixture and allow the lamp to cool fully before installation, removal, or servicing
• Do not touch the quartz envelope with bare skin during installation; oils from skin contact can cause the quartz to fail prematurely under heat — handle with clean gloves or a cloth
• Install and operate only in fixtures rated for this lamp's wattage and voltage, with adequate clearance from combustible materials
• Follow the manufacturer's specified burning position (horizontal, or per fixture design) — operating outside the rated position can shorten lamp life or cause failure
• Follow all applicable national and local electrical and fire codes for infrared heating installations

Compliance

• ISO 9001 Certified manufacturing
• Manufactured in the USA
• Specifications per Ushio's QIH product documentation; subject to change without notice by the manufacturer
