Technical Specifications and Application of 150W Halogen Infrared Heating Lamps

August 18, 2026

Let’s talk about the 150W Halogen Infrared Heater

If you need a punch of heat but don’t have the room for some massive heating element, this 150W halogen lamp is your best bet. It’s a short-wave infrared source, which is really just a fancy way of saying it puts a concentrated blast of heat exactly where you need it. Inside, there’s a tungsten filament tucked into a quartz tube filled with halogen gas. Simple, but it works. The heat side of things At 150W, you’ve got a sweet spot. It’s enough power to get surfaces hot almost instantly, but it won’t blow your circuit or overload your system. It’s fast. Really fast. You can get your material up to temperature in a matter of seconds, which makes it a lifesaver for small-scale curing or those annoying localized drying tasks. The secret in the glass We use quartz glass for the envelope because it can handle the shock of going from cold to scorching hot without flinching. But the real magic is the halogen cycle. Normally, filaments evaporate and the bulb turns black over time. The halogen gas stops that. It basically grabs the tungsten and puts it right back onto the filament. This keeps the light clear and the heat consistent for a lot longer. A quick warning Here is the thing: quartz is incredibly sensitive to oils. If you touch the glass with your bare hands, those fingerprints create “hot spots.” When you flip the switch, those spots can cause the glass to crack. **Do yourself a favor: wipe the bulb down with some isopropyl alcohol before you install it.**Your future self will thank you. Putting it to work These are great for swapping into PET blowing machines, shrink wrappers, or lab setups. We usually suggest the 150W version when you’re working in tight spaces and don’t want to accidentally melt your substrate. Just make sure your power supply matches the lamp’s voltage, or you’ll pop the filament the second you turn it on. And keep your reflectors shiny. The cleaner they are, the more heat actually hits your workpiece instead of wasting away into the air.
