Factory-Price Halogen Bulbs: Compact Heat for Industrial Work
We make halogen bulbs at a straight-up factory price, built for the engineers who need heat they can count on. This isn’t about cozy lighting. It’s about packing a ton of infrared heat into a small space, so your industrial lines keep moving. Think of these as workhorses. They’re made for the kind of work that demands a fast response and a steady output, day after day.
Power, Voltage, and Size—Why It All Matters
When you’re sizing up a halogen heating bulb, you’re really looking at three things: wattage, voltage, and length. That’s it. A 2500W rating gives you serious radiant power in a small package. Perfect when you need to heat one specific spot, fast. Running at 400V is a smart move, too. It means you get the same power with less current, so your wiring is simpler and you don’t need to oversize the conductors. It’s just cleaner for fixed equipment. And the 300mm length? That gives you a predictable heat zone that lines up with standard reflectors and oven openings. No guesswork.
What’s Inside: The Build That Earns Its Keep
The envelope is quartz, plain and simple. It can take the heat, and it lets the infrared energy through without a fuss. The halogen cycle is the quiet hero here. It keeps the filament clean even at scorching temperatures, which means the output stays stable over the life of the bulb. No fading. No surprises. We’ve also added a reflective coating on the tube wall. It pushes more energy forward, so more heat hits your target and less gets wasted sideways. And for the connector? We went with the standard R7s. It’s a direct swap for most industrial halogen heaters. You line it up, you wire it up. No custom parts, no headaches.
Where It Shines—And What to Keep in Mind
You’ll see these bulbs in action on PET blowing lines, plastic thermoforming, and packaging sealing—anywhere you need heat to show up and behave, immediately. The combo of high wattage, 400V operation, and that 300mm size gives engineers a repeatable heat module that’s easy to replace when it’s time. Now, here’s the reality check: that kind of concentrated heat needs proper machine cooling and shielding. Manage the ambient temperature, protect nearby parts, and this thing runs like it’s supposed to.
