400W halogen Heating Bulb: The Heat You Need, Where You Need It
We built this 400W halogen heating bulb for the industrial jobs that demand fast, focused heat. Forget the idea of it being just a light bulb—it’s a shortwave infrared heater, pure and simple. It packs a ton of power into a small space and is tough enough to earn its keep on a busy plant floor.
The Specs, Straight Up
The 400W rating is what you get—solid, dependable heat output. Now, here’s the thing about how it’s powered. In a lot of industrial setups, it runs on 400V, not your standard wall outlet voltage. That higher voltage keeps the current lower, which means less strain on your wiring. It also lets you use smaller switches and terminals. The bulb itself is short, usually around 300mm long. That compact size gives you a tight, precise heat zone. Perfect when you’re only heating a small part, a specific joint, or a narrow process area.
What It’s Made Of
Inside, the filament runs incredibly hot, so we don’t skimp on the housing. It’s encased in quartz, not regular glass. Quartz handles the intense heat shock and stays clear, even after being switched on and off again and again. And the halogen cycle? That’s the secret sauce. It takes evaporated tungsten and sends it back to the filament. This fights off blackening and keeps the output steady over the life of the lamp. For the connection, we use an R7s connector. It’s a practical, industrial choice that gives you a secure, two-contact fit. It’s easy to wire up and is consistent across different fixtures. If your machine uses an SK15 base instead, we can match that, too. The whole point is a drop-in replacement you can trust to stay aligned and reliable.
Where It Shines
This is the bulb you reach for when you need heat, fast. We’re talking about applications like plastic sealing, adhesive curing, and drying components. The shortwave infrared output gets hot almost instantly, so you can shorten those cycle times and keep things moving.
The Honest Trade-Off
Let’s be real. Packing this much power into a small area means things get hot. That means your fixture and the parts around it need to be ready for the heat. You’ve got to plan for proper heat shielding, good airflow, and thermal protection. We build these bulbs to take the heat, but your machine has to be built to manage it, too.
