One burns out, or a glass edge isn&rsquo;t curing right, and the immediate reaction is to order another one with the same wattage and pop it in. We see it all the time. But here&rsquo;s the thing: swapping a lamp without looking at why it failed is just a band-aid. You&rsquo;re ignoring the actual problem.</p> <h2 id="glass-is-picky">Glass is Picky</h2> <p>Glass doesn&rsquo;t just &ldquo;take&rdquo; heat. Depending on how thick it is or what coating you&rsquo;ve used, it absorbs infrared radiation differently. Shortwave IR goes deep. Medium-wave stays on the surface. If your lamps are tuned to the wrong wavelength, you&rsquo;ll get those annoying cold spots right in the middle of the glass. The temptation is to just crank up the voltage to force the heat in. Don&rsquo;t do that. All you&rsquo;re doing is frying your filaments faster.</p>
