You need those thermal gradients to be spot on to get rid of internal stress, but if you mess up, you&rsquo;ll warp the lens geometry. It&rsquo;s a delicate process. Here&rsquo;s the thing: we build our <a href="https://o-yate.net">infrared</a> lamps for the real world. And the real world has messy power grids. You can&rsquo;t just take a lamp built for a 110V US outlet and plug it into a 480V or 575V industrial line. If you do, you&rsquo;ll blow the filament instantly.<strong>Pop. Gone.</strong></p>
