Half white reflector halogen heating bulb 380mm 400v 2000w quartz tube heating lamp

Introduction

We built this half-white reflector halogen heating bulb for one reason: to give industrial processes heat that snaps on and responds instantly. It’s a direct-fit solution—no messing around. The whole package is a 380mm quartz tube, runs on 400V, and delivers 2000W. In other words, it packs serious infrared punch into a tight space.

Power, Voltage, and Size—Why It Matters

At 2000W packed into a 380mm tube, you get heat density that can really move the needle—fast. Temperatures rise quickly, especially in those confined zones where you need heat right now. The 400V rating isn’t random. It’s a smart match for industrial power setups. Higher voltage means the lamp draws the current it needs without dragging down voltage over long wire runs. That also keeps the load easier on your control gear. Here’s the nice part: if your line is already set up for 400V, you can spec fewer transformers and skip the heavy-gauge wiring headaches. And the 380mm length? It was chosen to drop straight into standard reflector assemblies and oven cavities. So you can replace the heat source without redesigning the whole chamber.

Materials and Design—Built for the Grind

The quartz tube handles high operating temps with no fuss, and it stays steady even when you cycle the heat quickly. Inside, the halogen cycle keeps the filament clean, which helps the output stay consistent over the life of the lamp. That matters when your process temperature can’t drift. Then there’s the half-white reflector coating. It redirects part of the radiation forward, so you get tighter, more directional heating—and less wasted energy. And the R7s base? Practical, tough, and easy to install. It’s the kind of connector you don’t have to fight, even when you’re doing repeated replacements out on the line.

Where It Shines—And What to Keep in Mind

This lamp is for the moments when you need heat that turns on fast and turns off fast, with predictable performance. Think thermoforming, drying, curing, and localized heating in packaging and plastics equipment. With 2000W, 400V, and a 380mm length, it’s built to be a drop-in replacement that makes retrofits straightforward. Now, a reality check: that 2000W density creates serious heat. The equipment around it needs proper airflow and thermal management. If the chamber can’t shed the heat, you’ll shorten component life. But when you match this lamp to a system that can handle the thermal load, you get stable output and maintenance that stays simple.
