Why we put our bathroom lamps through a “humidity hell”
Let’s be honest: bathrooms are absolute nightmares for electronics. You’ve got steam everywhere, random water splashes, and temperatures that swing from freezing to boiling in a matter of minutes. If we just tested a lamp on a dry workbench and called it “good to go,” it would probably blow a fuse or burn out within six months of hitting a real home. We don’t want that phone call. So, we put every single batch through what I call damp-heat aging tests. The battle against moisture Here’s the thing about humidity: it loves to find a way in. Water vapor sneaks into the housing and settles right on the lamp terminals. Once that happens, you get these tiny “leakage currents.” In plain English? That’s how you end up with a tripped breaker or a dead lamp. To stop this, we lock our lamps in a chamber, crank the humidity up to 95%, and bake them for hundreds of hours. We’re hunting for any sign of rust on the contacts or tiny leaks where the quartz meets the metal. If it can’t survive our chamber, it definitely won’t survive your shower. The “Thermal Shock” problem It isn’t just the wetness that kills these things—it’s the cycle. An infrared lamp goes from room temperature to scorching hot in seconds. That makes the materials expand and contract violently. Now, imagine doing that while the air is thick with steam. That’s “thermal shock.” We flip the lamps on and off, over and over, in that humid air. We’re checking to see if the seals crack. Because if a seal gives way, moisture hits the filament, and pop—there goes your lamp. A little extra bulk for a lot more peace of mind To make sure these lamps actually last, we have to over-engineer the seals and insulation. Because of that, you might notice the housing feels a bit heavier or looks slightly bulkier than a heater made for a dry living room. It’s a trade-off we’re happy to make. I’d rather spend a bit more on materials now than have a customer’s lamp fail the second they take a hot shower. After the test, we check the insulation resistance. If the numbers aren’t exactly where they need to be? We scrap the whole lot. No exceptions.
