transparent halogen tube

June 8, 2026

Introduction

We built this transparent halogen tube for one simple reason: to give you heat you can actually control, packed into a small space. This isn’t about gently warming the air around you. It’s about delivering direct, focused energy exactly where you need it—when you need it. For jobs that demand an instant response and pinpoint temperature control, this is your go-to.

The Power Behind It

Here’s the thing: it comes down to power density. You get 2500W of output packed into just 300mm of tube. That translates to serious heat flux, perfect for heating a small zone or a specific line on a machine. Now, the 400V voltage is a trade-off. It lets us cram all that wattage into a smaller physical size, but it means your control gear and wiring have to be up to the task. Spec the system to handle the load, and this tube will deliver the heat, no problem.

What It’s Made Of

The tube itself uses a transparent quartz envelope. And that’s not just so you can peek inside. Quartz handles the intense heat and the shock of rapid on/off cycles without breaking a sweat. Inside, the halogen cycle keeps the filament clean, which means a longer life and steady light and heat output over time. And the R7s connector? It’s a practical, two-pin design that handles the current and makes this tube a simple, drop-in replacement for standard fixtures.

Where It Shines

This design really comes alive in applications like PET blowing or shrink tunnels. Because the body is transparent, you can keep an eye on the heating zone without shutting the line down. You see a problem, you fix it—simple. The focused infrared energy hits the product directly, not the air around it. That means faster cycle times and less wasted energy. Just be aware—this thing runs hot. So you need to make sure your machine’s cooling and clearance specs are squared away before you integrate it. We built this tube to take the daily grind on the factory floor. It’s a tough, direct-heat workhorse for engineers who need power, precision, and a component they can wire up and trust to just do its job.
