On the floor, a tired or drifting heater lamp doesn’t just throttle the line—it writes scrap. Underheat the preform and you get brittle bottles. Overheat it and you get crystallization and haze. The Sidel Matrix heater lamp spares we supply are built to keep your heating tunnel predictable, cycle after cycle. We build these emitters around short-wave infrared halogen technology—quartz envelope, tight filament design—so they respond quickly to PLC control. The specs stay true to OEM intent: rated wattage and voltage matched to the heater block, standard R7s base, and the right arc length and end-seal geometry so the lamp seats clean in the reflector. That gives you stable spectral output and repeatable heat density across the preform wall—exactly what matters when you’re running thin-wall or high-barrier grades. Compatibility comes first, and we don’t leave it to guesswork. These lamps are engineered for Sidel Matrix series blow molders, and they also drop into common heating sections on Krones Contiform and HyPET platforms. When you replace lamps with parts that match the original thermal profile, warm-up is faster, temperature swings in the tunnel settle down, and bottle weight and top load hold steady. The payoff: fewer rejects, less downtime on lamp changes, and lower energy use per thousand bottles. Installation is straightforward, but the heating window is sensitive. Use clean gloves, check reflector condition, and confirm lamp alignment to avoid hot spots. Match voltage and connector type to the machine label—wrong wattage changes the heating curve and can cut lamp life short. For best results, pair the lamp change with a routine reflector clean and a calibration of your temperature sensors.
