Let’s Talk About These 355mm 440V Quartz Halogen Lamps
If you need a massive amount of heat hitting one specific spot, these are your best bet. We built these lamps to pump out 2000W of power in a tight 355mm frame, so you get a lot of punch without needing a giant machine. The Nitty-Gritty on Power Here’s the thing: running these at 440V is a bit different than your standard 230V tubes. It pushes more current through the tungsten filament, which means the lamp gets hotter, faster. You’re moving into that shortwave IR range, so you aren’t sitting around waiting for things to warm up. Plus, since 355mm is a pretty standard size for industrial ovens, you can usually just swap these in for your old, burnt-out tubes without any headache. Why the “Half-White” Look? You’ll notice one side of the quartz has a white, aluminum-based coating. That’s not for looks. It’s there to act like a mirror. Instead of letting heat bleed backward into your machine’s housing—which is just a waste of electricity—the coating bounces all that energy straight down onto your workpiece. It’s way more efficient. And we use quartz because it’s tough. You can flip the switch from a cold start and it won’t shatter from the sudden heat jump. It just handles it. Real-World Tips for the Shop Floor You’ll probably be dropping these into shrink-wrap tunnels or PET blowing machines. Just a heads-up: 2000W is a lot of heat in a small space. Make sure your cooling fans and reflectors are actually up to the task. If the air isn’t moving enough, the ends of the lamps will fry way sooner than they should. One last thing—and this is important—keep the glass clean. If you touch the quartz with oily fingers, those prints create “hot spots.” Eventually, the glass stresses out and the tube pops. Grab some isopropyl alcohol and give them a quick wipe before you fire them up. Your lamps will thank you.
