Why we put our bathroom lamps through “damp-heat” torture

Let’s be honest: bathrooms are a nightmare for electronics. You’ve got steam everywhere, constant swings in temperature, and the occasional stray water droplet landing exactly where it shouldn’t. If a heating lamp isn’t built for that chaos, it’s toast. The seal leaks, the filament ruins, and the whole thing burns out in a few weeks. Nobody wants to deal with that.

How we try to break them

We don’t just “test” these lamps. We basically put them through a boot camp of accelerated aging. We shove our infrared units into high-humidity chambers, crank up the heat, and leave them there for hundreds of hours. It’s a shortcut to simulate years of real-world bathroom use. We’re hunting for that one tiny gap—a microscopic leak in the quartz or a weak spot in the terminals—where moisture manages to sneak in. Here’s the thing: water vapor is the natural enemy of the halogen cycle. If even a tiny bit of moisture gets past the connector, the pressure inside shifts and the filament snaps. Simple as that.
