A Real Look at the 1500W Halogen Heating Lamp
We built these 1500W halogen lamps for those moments when you need a massive amount of heat, and you need it right now. They work by using a tungsten filament tucked inside a quartz tube filled with halogen gas. Here’s the clever part: that gas actually pushes the tungsten back onto the filament. This keeps the quartz from turning dark and murky, which means the lamp lasts a lot longer before you have to replace it. Handling the Power 1500W is a lot of juice. It creates a really intense heat footprint. Before you plug these in, double-check your wiring and power supply. You don’t want any voltage drops messing with your performance. And because the heat is so aggressive, you’ve got to be smart about airflow. If you’re squeezing these into a tight PET blowing machine or a small oven, make sure your cooling fans are actually up to the task. If the ends of the lamp get too hot, your connectors might melt, or the lamp will just burn out way too soon. The Hardware Side of Things The quartz tube is there to handle the wild temperature swings between the glowing filament and the air around it. We used standard connectors—mostly R7s slide-in bases—because nobody wants to spend their afternoon rewiring a whole rig just to swap a bulb. It’s a quick pop-out, pop-in process. But a quick word of warning:don’t touch the glass with your bare hands. I know it sounds picky, but the oils from your skin leave spots on the quartz. When the lamp heats up, those spots create “hot zones” that can actually cause the tube to crack. Use a clean cloth or gloves. It’ll save you a headache. Putting Them to Work You’ll mostly see these in industrial drying or PET preform heating. The short-wave radiation hits the material fast, which cuts down your cycle times. It’s great because when you tweak your PID controllers, the response is almost instant. Just keep an eye on your focal distance. Since the heat density is so high, if the material is too close, you’re going to scorch it. Find that sweet spot, and you’re gold.
