Now RTC original OEM lamps are available built to your order.  Factory original lamps, developed by RTC and manufactured in the USA by USHIO. 

IR Lamp

These lamps perfectly match the OEM lamps in your RTC and/or LCI IR furnace. Compared to "compatible lamps" by  other manufacturers, these original equipment IR lamps operate at lower temperatures at their connections prolonging the life of each lamp and reducing premature lamp failure.  Suitable for all LCI and RTC IR furnaces, RTC ovens and FurnacePros and/or RTC dryers. 

We have some lamps in stock in limited quantities. Other lamp models are available built-to-order with 4-8 week lead time. Call (714) 935-0302 x230 or email parts@furnacepros.com for availability.

Small changes in composition cause changes in the EMF signal generated by the wire pair and can cause errors in the temperature signal. Replacement once per year, or every 2 years in clean environments, is recommended.
