half white reflector halogen heating lamp

Introduction

We built this half white reflector halogen lamp for one reason: to give industrial heating jobs a seriously compact, high-intensity heat source. It’s all about packing a lot of heat into a small footprint. We pair a halogen-filled quartz tube with a half-coated reflector, so you get a tight, directional beam of infrared. No fuss. Just focused heat where you need it.

Power, Voltage, and Geometry: The Practical Details

When we size these lamps, we focus on three things: wattage, voltage, and length. Why? Because those three determine the heat density and how easily the lamp fits into your machine. High wattage in a short tube means concentrated infrared energy. Perfect for spot heating and getting things hot fast. Voltage is another piece of the puzzle. It has to match your control gear and wiring. Here’s the neat part: if we spec a high-voltage version, you run less current for the same power. That can let you use smaller wires and cut down on voltage drop over a longer run. But it does come with a trade-off. The lamp and its terminals have to be rated for that higher voltage, and you have to be spot-on with your insulation and clearances.

The Build: What Makes It Tick

The quartz envelope isn’t just tough—it handles high temps and stays clear, so the infrared energy gets through. The halogen gas is the secret to longevity. It lets the filament run hotter without quickly blackening, because the halogen cycle puts tungsten back on the filament. The result? Stable output over the life of the lamp. That half white reflector coating? It’s not just for looks. It reflects infrared forward while letting the back half of the tube radiate heat away. You get better directional efficiency and less wasted energy. For mounting, we use an R7s connector. It’s straightforward, secure, and reliable. It’s a common industrial standard, which makes replacement easy and keeps alignment issues off the table.

Where It Shines (And What to Watch For)

These lamps shine when you need fast, localized heat. Think plastic processing, coating curing, or assembly work where you need heat on demand. Because the output is directional, you can put the heat exactly where you want it. That helps shorten cycle times and keeps heat from bleeding off into the surroundings. We size the lamp to match your process, but you still need to plan for the heat load. A high-wattage lamp throws off serious heat density, so your machine needs proper cooling and shielding. Think of it as a drop-in heat source, but take a moment to check the surroundings. A little planning keeps nearby components from getting too hot.
