It&rsquo;s a genuine risk. Since there&rsquo;s no air to help carry heat away, things behave differently. One tiny electrical arc can ruin your entire chamber or fry an expensive substrate in a heartbeat.</p> <h2 id="why-we-test-every-single-lamp">Why we test every <a href="https://o-yate.net">single</a> lamp</h2> <p>We don&rsquo;t believe in &ldquo;batch sampling.&rdquo; That’s a gamble we aren&rsquo;t willing to take. Instead, every single lamp tube goes through a mandatory HiPot (withstand voltage) and insulation resistance test before it even thinks about leaving our shop. Here&rsquo;s the thing: vacuum heaters live under brutal thermal stress. You might have a microscopic crack in the quartz or a tiny flaw in the electrode seal that looks fine during a basic continuity test. But the second that lamp hits operating temperature? That&rsquo;s when the trouble starts. By pushing high voltage—way beyond what the lamp normally sees—we force those hidden weaknesses to show their face. If a tube leaks current or arcs during the test, it&rsquo;s gone. Straight into the scrap bin.</p>
