Technical Deep-Dive: Power and Dimensions
We designed these carbon heater bulbs to pack a serious punch—high-power infrared heat, but in a surprisingly small package. The 400V rating is a game-changer for running higher wattage over distance. It keeps the current manageable, so you don’t need bulky wiring and you won’t lose your head over voltage drop. And the size? A 300mm length with a 10mm diameter. It creates a tight, concentrated heat zone that slips right into snug reflectors and narrow spaces. You tell us the power you need, and we make sure the design delivers it exactly where you want it.
Material and Design
Inside, a carbon filament is nestled in a quartz envelope. We chose quartz because it handles sudden temperature shifts like a champ and lets infrared energy pass through without a hitch. A halogen filler keeps that filament clean, which means the output stays steady over the life of the lamp—no annoying blackening. We also added a reflective coating on the outside. It bounces wasted energy back onto the filament, which boosts the temperature and cuts down on warm-up time. And the R7s double-ended connector? It locks the lamp in place and handles the high current without needing extra hardware. Just a solid, secure fit.
Application and Benefits
These heaters shine in industrial settings where space is tight and you need heat, fast. Think PET blowing, thermoforming, plastic welding—places where you need to hit a setpoint and stay there. The heat density is intense, which means you get up to temperature quickly. But with that kind of power, you do need to plan for proper cooling and mounting to prevent hot spots. You can count on consistent performance throughout the rated life. Just make sure your thermal management is as sharp as the wattage density.
