118mm Ruby Halogen Heat Lamp 240v 300w

May 28, 2026

We built the 118mm Ruby Halogen Heat Lamp for one reason: to pack serious industrial heat into a tiny space. It’s a compact, high-intensity infrared emitter that cranks out 300W at 240V. Think of it as a pinpoint blast of warmth that doesn’t take up a lot of real estate.

Here’s the thing about the size and power

We went with a 118mm length and a 300W rating because you need serious power density without a bulky lamp. This lets you squeeze high heat into those tight corners on your equipment. And the 240V rating? That’s standard industrial voltage. So you can wire it straight into your existing control panels and power circuits. No need to tear apart your electrical setup just to make it work.

Why the ruby tint and the design matter

The ruby-tinted quartz envelope does two key things. It filters out the visible light and lets the shortwave infrared through. That infrared penetrates materials fast, getting right to work. Inside, the halogen cycle keeps the filament clean, so the lamp lasts longer than a standard incandescent. And the R7s double-ended base gives you a solid, low-resistance connection. It’s a straightforward, drop-in replacement in any compatible fixture.

Where it shines—and what to keep in mind

This setup is perfect for plastic processing, drying coatings, and any localized heating that needs a quick response. It hits full output fast, so you get instant thermal control. But here’s the catch: that power comes concentrated. The envelope runs hot—so your fixture and machine have to be rated for those temperatures. You’ll want proper heat shielding and airflow to protect nearby parts and keep things running smoothly.
