It’s More Than Just a Light Bulb

Most people treat preheating lamps like light bulbs in a hallway. They look at the voltage, check the length, and find something that fits the socket. Simple, right? But here’s the thing: getting the wattage right keeps the lamp from blowing out, but the lamp is only one small part of the puzzle.

The Heat Struggle

CNC glass cutting is all about balance. You need that specific temperature gradient to stop the glass from stressing out while you’re scoring it. That’s why we use short-wave infrared—it punches through the surface fast. But there’s a catch. If you shove a high-wattage tube into a housing with bad airflow, you’re basically baking your machine frame. It’s a constant tug-of-war. You want more heat to speed up the line, but your cooling system can only take so much before it gives up.
