Product Overview

The GE 22838 QH2500T3/CL is a tubular quartz halogen infrared lamp engineered for industrial process heating, drying, curing, and warming applications. At 2500W and 480V, this lamp delivers radiant infrared energy output from a compact T3 quartz envelope (28.80" long), making it suitable for installation in industrial heating fixtures and equipment designed for this exact wattage and voltage.

The 2400K color temperature reflects operation at a filament temperature calibrated for infrared process heat rather than general illumination — producing a high proportion of infrared radiation relative to visible light. The R7s recessed single contact base (each end) provides a connection suited to industrial fixture mounting. Horizontal burn position only — operating at other orientations will cause premature filament sag and failure.

Compatible Applications

Industrial process heating — Drying, curing, baking, and thermal processing equipment requiring 2500W 480V tubular quartz infrared sources.
Commercial warming and heating equipment — Food service warming equipment, outdoor patio heaters, and comfort heating fixtures using T3 quartz halogen elements.
Retrofit and maintenance replacement — Confirm voltage, wattage, MOL, diameter, burn position, and termination style before ordering.

Before Ordering — Verify

Voltage: Confirm equipment is rated for 480V. Do not install on a mismatched voltage system.
Wattage: Confirm the fixture or equipment is rated for 2500W.
Burn Position: This lamp is rated for horizontal operation only. Vertical or angled installation will cause premature filament failure.
Physical Dimensions: Confirm 28.80" MOL and 0.375" (T3) diameter fit within your fixture or equipment lamp housing.
Termination: Confirm your fixture accommodates r7s recessed single contact base (each end).

Safety and Handling Guidelines

Extreme Heat Warning: This lamp operates at very high surface temperatures. Use only in approved fixtures or equipment rated for high-temperature quartz halogen infrared operation. Keep all combustible materials away from the lamp and fixture.
Do not touch the quartz envelope with bare hands. Skin oils cause hot spots leading to premature failure. Use clean gloves or a lint-free cloth. If accidentally touched, clean with isopropyl alcohol before use.
Horizontal Burn Position Only: Operating vertically or at an angle will cause premature filament sag and lamp failure.
Do not exceed rated voltage. Operating above 480V dramatically shortens lamp life.
Allow Complete Cool-Down: Allow the lamp to cool fully before handling or replacement.
Disconnect Power: De-energize the circuit before lamp replacement. 480V systems carry lethal voltage.
