Technical Deep-Dive: Power, Voltage, and Dimensions

The twin-tube carbon fiber heating lamp is engineered for industrial processes that demand high heat density in a compact footprint. We spec these lamps to deliver 2500W of power at 400V. This high-voltage, high-power combination is intentional. It drives a high filament temperature, which translates directly into rapid heat-up and high infrared output. The 300mm length is a standardized size, chosen to fit existing machine slots for heating zones without redesigning the entire assembly. You get a lot of heat out of a small space, but that also means the surrounding components must handle the thermal load. Make sure your cooling and thermal management are up to the task.

Material & Design: Carbon Fiber, Halogen, and R7s

The core technology here is the halogen cycle, paired with a carbon fiber filament. The halogen gas inside the quartz envelope prevents the filament from evaporating and blackening the tube. This keeps light and heat output stable over the life of the lamp. The carbon fiber filament itself handles the thermal shock better than standard tungsten, giving you more consistent performance when the lamp cycles on and off. The R7s connector is a double-ended, ceramic-based design. It handles the high current and high temperature without melting the wiring or the socket. It’s a simple, robust interface that makes wiring straightforward on the shop floor.

Application & Benefits: Precision Heating in Tight Spaces

This lamp configuration is built for industrial heating tasks where space is at a premium and response time matters. Typical applications include PET blowing, plastic thermoforming, and adhesive curing. The twin-tube design gives you two independent heating elements in the footprint of one, which simplifies zoning and control. The high-density infrared output targets the material directly, rather than heating the entire machine enclosure. This reduces wasted energy and speeds up cycle times. The trade-off is thermal load on the immediate environment, but when your system is designed for it, this lamp delivers reliable, repeatable heat where you need it most.
