Low wattage heater

We built this low-wattage halogen heater to squeeze a surprising amount of heat into a tiny space. It’s for those industrial setups where room is at a premium, but you still need heat that’s steady, precise, and dependable. Here’s the inside story. We went with a 300mm tube running at 400V. High voltage means we can hit the wattage you need with lower amperage. That lets us keep the wiring thinner and cuts down on voltage drop over distance. The 300mm length packs a lot of power into a small footprint—so you get serious heat in a tight spot. But that heat is concentrated, so your cooling system needs to be ready for the local temperature rise. Plan accordingly. The core runs on the halogen cycle, which keeps the filament intact. That means less blackening and steady output over the life of the lamp. The quartz envelope has a coating that directs infrared energy toward the target, so less heat goes to waste. And the R7s connector? It’s industrial-grade, made to handle the expansion of the quartz tube and lock in a solid, vibration-resistant electrical connection. No fuss, no wobble—just a secure fit. This setup shines when you need fast response in tight zones—think PET blowing or small-area preheating. The low-wattage approach gives you control without overwhelming the process. And because it uses an R7s base, it slides right in as a replacement when maintenance time comes around. Just remember: the heat is focused. So set up your airflow and shielding thoughtfully.
