Introduction
We built this replacement lamp for one reason: to fit your SIG Blomax 4/6/8/10 like it was born there. Whether you’re moving from the older SBO models to the new Matrix line, it just works. No rewiring. No machine tweaks. No messing with the socket. It drops in the same way the original did, so you’re back up and running without the headache.
The Nitty-Gritty
This isn’t a run-of-the-mill bulb. It’s engineered to handle the heat and power needed for PET blowing. So we matched the 400V input to the Blomax electrical setup, keeping the current draw exactly where your machine expects it. And the 2500W output gives you the thermal punch to heat preforms fast and evenly. Size matters, too. At 300mm long, the tube fits the tight heating zone of the Blomax series like a glove. That length gives you even coverage across the preform. Cut it short, and you’ll get hot spots. Make it too long, and it won’t even fit the chamber.
Materials and Design
Inside, you’ve got a halogen-filled quartz tube that keeps performance steady, even after countless heat cycles. The halogen cycle helps keep the filament clean, so the output stays consistent over time—exactly what you need when the heat keeps switching on and off. The R7s connector? That’s the standard on these machines. It gives you a solid, two-contact connection that can handle the high current and stay put, even when there’s vibration. The ceramic base and quartz body can take the rapid heat-up and cool-down that blowing cycles demand, so you don’t have to worry about thermal shock.
What It Feels Like on the Floor
Here’s the best part: when a lamp burns out, you swap it and get back to work. No re-pinning. No rewiring. No changing the footprint. It matches the original dimensions and electrical specs, so the install is truly plug-and-play. That means uptime. Pure and simple. Just one thing to keep in mind: this is a 2500W, 400V tube, and it runs hot. Your machine’s cooling system needs to be up to the task. As long as you keep the airflow and heat sinking as designed, this lamp will deliver steady, repeatable performance across the entire Blomax family.
