Ushio 1003159 QIH400-2500/ZH – 2500W 400V Quartz Infrared Heater Lamp

The Ushio 1003159 QIH400-2500/ZH is a 2500W, 400V quartz infrared heater (QIH) lamp, built with clear quartz and a flat ceramic base with lead wire (no adhesive). It has a Maximum Overall Length of 381mm. Rated color temperature is 2500K and average life is 5,000 hours.

Technical Specifications

*Outer diameter comes from the existing ADL Supply listing and is not stated in the Ushio QIH catalog for this part number.

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 1003159 is rated 2500W at 400V with a 381mm maximum overall length. It uses clear quartz. The lamp terminates in a flat ceramic base with lead wire (no adhesive).

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 400V — QIH lamps are voltage-specific across this family; a lamp built for one voltage is not interchangeable with another
• Confirm base type (Flat Ceramic Base with Lead Wire (no adhesive)) 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 381mm against the available socket-to-socket or clip-to-clip distance in the fixture
• This lamp has a one-sided white coated reflector — confirm reflector orientation requirements for the fixture, since it directs heat rather than radiating uniformly around the tube
• Ushio's QIH catalog does not list this part number. Dimensions, color temperature and life come from the existing ADL Supply listing; the glass, jacket, burn position, reflector and base are decoded from the part number using Ushio's part number guide. Confirm against the lamp or Ushio before ordering.
• Country of manufacture is not confirmed for this part number, so none is stated here. Verify before relying on it for customs or compliance.

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

• Specifications per the existing ADL Supply listing and Ushio's QIH part number guide; subject to change without notice by the manufacturer
