Ushio QIH105-500T/S #1001286 500W Infrared Heater

The Ushio QIH105-500T/S (Order Code 1001286) is a 500W 105V double-ended quartz halogen infrared heater lamp engineered for precision optical heating, industrial process heating, and thermal processing applications requiring stable, focused infrared output over an extended service life. Delivering consistent 2500K infrared radiation through a compact 223mm translucent T-type quartz envelope with metal sleeve and lead wire terminations at each end, this Japan-manufactured industrial halogen element provides a 6,000-hour rated service life in approved enclosed halogen IR fixture assemblies.

ADL Supply Expert Application & Replacement Guide

The Ushio QIH105-500T/S is primarily specified by process engineers, OEM equipment manufacturers, and industrial maintenance teams for precision infrared heating assemblies, optical processing equipment, thermal cure systems, and specialty industrial fixtures where repeatable focused infrared output and a long 6,000-hour element life are both operational priorities. This is an industrial infrared heating element that terminates via metal sleeves with lead wires at each end — it is hardwired directly into the fixture's terminal connections, not inserted into a plug-in base socket. All wiring and replacement work must be performed by qualified personnel familiar with the equipment's electrical system. The design voltage of 105V is a specialty industrial supply voltage — it is not compatible with standard North American 120V circuits and the equipment's internal regulated power supply or transformer tap must output exactly 105V under load before installation. Over-voltage operation, even at 120V, will significantly shorten element life or cause immediate failure. The 223mm overall length and 11mm maximum tube diameter must physically match the fixture's element channel before ordering — confirm both dimensions against the equipment's maintenance documentation or existing element.

Operation, Safety & Mounting Compliance

Voltage Requirements, Wiring & Process Repeatability

The 105V design voltage is a specialty industrial supply level — the equipment's internal regulated power supply or dedicated transformer tap must output exactly 105V under operating load. Standard North American 120V branch circuits are not compatible and will over-drive the element, causing significantly accelerated filament degradation or immediate failure. The lead wire terminations must be connected to the fixture's terminal block using connectors rated for the element's operating temperature and current load. Because the 2500K infrared output and 6,000-hour rated life are calibrated to exact voltage operation, any sustained deviation from 105V will compromise both the thermal output consistency that process repeatability depends on and the rated service interval.

Quartz Handling, Thermal Safety & Enclosed Fixture Requirement

This element must be installed exclusively in an approved enclosed halogen IR fixture assembly — open-air operation creates both a fire hazard from the quartz tube's extreme operating temperature and a burn hazard to personnel from uncontained infrared radiation. Never handle the quartz tube with bare skin — skin oils bond permanently to the quartz surface during thermal cycling and create localized hot spots that accelerate premature tube failure. Always handle using clean cotton gloves or the element's original protective packaging. In high-vibration industrial environments, verify that the metal sleeve terminations are mechanically secure in the fixture's clamping blocks before powering the assembly. Allow adequate cool-down time before accessing the fixture after operation.
