Introduction
So, picture this: you build a mirror heater that’s really just a dedicated infrared halogen lamp. We designed it to slide right into bathroom mirror defogging setups. It’s small, but packs a punch. The whole point? Keeping your view clear by wiping out condensation on the glass. The idea is simple—radiant heat—but getting it right takes serious care. You need the power density nailed down, and the parts have to hold up, day after day.
The Nitty-Gritty
Let’s talk power. These lamps typically run at 2500W and need a 400V supply. That combo gives you enough heat across the whole mirror without overhauling your electrical system. And it has to fit. We’re talking about a footprint that’s roughly 300mm long, just enough to slip into standard mirror frames. Because space is tight, the power is packed in tight. That means the lamp has to handle heating up and cooling down—over and over—without flinching.
What It’s Made Of
Inside, you’ve got a quartz envelope filled with halogen gas. That mix keeps the filament temperature steady, so the lamp doesn’t burn out early and stays consistent over its life. The shortwave infrared heat hits the mirror surface directly, so it warms up almost instantly. And for the connection? We use an R7s connector. It gives you a solid, two-point contact that can handle the current, and it makes replacement a breeze when it’s time for a new one.
How It Feels in the Real World
When it’s installed, this thing clears fog almost instantly. It’s fast. Really fast. The compact size makes it easy to work with, and the R7s hookup keeps wiring straightforward. Now, there is one thing to keep in mind. All that heat density means the mirror frame and mounting hardware will get hot. So, make sure the surrounding parts can take the temperature. When you manage the heat properly, you protect the components from wear and tear, and that’s what keeps the whole system running for the long haul.
