But here&rsquo;s the catch: usually, that rating only covers the outer shell. The actual electrical junctions? That&rsquo;s a different story. In high-wattage infrared systems, the real danger zone is right where the lead wire hits the heating element. We see it all the time. The heat from the lamp travels backward along the wire, basically baking the insulation until it gets brittle and cracks. Then, the first bit of rain or dew hits those cracks, and boom—you&rsquo;ve got a short circuit.</p>
