Why we built this
We set out to build a 12V, 150W halogen lamp that acts like a compact heat source for industrial machines—one that fits right into low-voltage DC or AC control circuits. It was designed for those tight, awkward spaces where you need heat fast, and you need it under control, without having to rewire the whole plant.
The 12V choice—why it matters
The 12V rating isn’t arbitrary. It lets you wire the lamp straight into what you already have—control transformers, PLC power supplies, even battery-backed systems. At 150W, you get serious heating power in a small package, but the current stays manageable. That makes conductor and switch sizing straightforward, and it helps keep voltage drop from becoming a headache on longer cable runs.
What’s inside—built for the real world
Inside, the filament runs on a halogen cycle. That means it can run hotter than a standard incandescent without the glass getting dark over time. The envelope is quartz, chosen because it handles sudden temperature swings without cracking. If your machine cycles on and off a lot, that stability matters. And the R7s double-ended cap? It locks in place cleanly. No wobble. No arcing when things get shaky.
Where it shines—and how to use it
This lamp is ideal when you need heat to come up quickly and you don’t have room to spare—think resin heating, sealing bars, small ovens. The heat profile is consistent, and swapping a lamp in the field is simple. Just keep in mind: the quartz envelope gets very hot on the surface. Give it clearance, and plan for heat shielding. A little space and proper mounting go a long way in protecting nearby parts.
