On the plant floor, the Sidel SBO 20 Series 2 heating tunnel doesn’t cut you much slack when preform heat is off. If the lamps aren’t pulling their weight, you end up with weak biaxial stretch, walls that run thick, and a growing pile of scrap. And you get unplanned stops while you chase the right temperature profile.
What matters, technically
We built this replacement lamp to match the Sidel SBO 20 Series 2 OEM envelope. Same halogen infrared output, same rated power, same overall length, and the correct R7s connector interface. The quartz envelope is chosen for quick thermal response and stable emissivity across the preform heating window, so you can hold setpoint instead of chasing drift. We spec it to the same mechanical footprint, so it drops straight into the existing lampholders—no bracket changes.
Why it works in this machine
You get OEM-grade heating behavior, but at a direct-replacement price. The heat-up curve stays the same, the control stability stays the same, and the repeatability from bottle to bottle stays the same. That means fewer thickness excursions, less regrind, and more uptime between lamp changes. In practice, many users see stable output through 5,000+ hours, which stretches replacement intervals and helps you trim spare-part inventory. Energy use stays aligned with the original design because the emitter profile matches the reflector geometry in the SBO heating zone.
The practical details
Installation is straightforward. Power off, let it cool, swap the lamps, then re-check your temperature profile. **Match the lamp to the reflector condition.**If the reflectors are heavily oxidized, you can still lose output even with a good lamp. Also confirm your power supply and terminal connections are clean and tight. Loose contacts can create hot spots that shorten lamp life.
