Stop Replacing Your SBO 20 Series 1 Lamps Every Other Week
If you’re running a SIG Blomax or Sidel SBO line, you know the frustration. You’re in the middle of a run, and suddenly—pop. Another tube breaks. It’s usually thermal shock or just plain wear and tear on the quartz, but it’s a headache nobody needs. We got tired of seeing those lamps fail, so we rebuilt our replacement lamps for the SBO 20 Series 1 to actually hold up. The heat is the enemy. Here’s the thing: your PET preforms need a very specific amount of infrared energy to hit that glass transition temperature. If the neck overheats, you’re in trouble. To keep your speeds up, these lamps have to pull a lot of wattage, which creates an insane amount of heat density. But here is a pro tip:keep your oven reflectors clean. If they’re dirty, the heat bounces straight back into the lamp envelope. That softens the quartz until it eventually just gives up and burns out. It’s a simple fix that saves a lot of money. Built to take a beating Most standard lamps fail at the pinch seal because they can’t handle the constant vibration and the rapid swing between hot and cold. We fixed that by using a reinforced quartz composition. It’s tougher. It’s more resilient. And the best part? We kept the footprint exactly the same as the OEM spec. You just pop them in. No messing with your wiring, no fighting with the brackets. They just fit. A reality check on the hardware Now, I want to be honest with you. These lamps are tougher, but they aren’t magic. Physics still applies. If your cooling air is all over the place, you’re still going to see premature failures. A reinforced tube helps, but it can’t fight a bad environment. Plus, keep an eye on your power. Voltage spikes will pop a filament regardless of how strong the quartz is. Before you swap in your new tubes, do yourself a favor: check your contactors and wiring. Make sure the power coming in is clean, and your new lamps will last a whole lot longer.
