We built this infrared wall heater around a high-output halogen quartz tube for one simple reason: you need focused radiant heat, not a room full of warm air. It’s for engineers who want a compact, direct heat source that hits the target—right where you need it—in localized processes and enclosures. Here’s the thing about the power. The tube is rated at 2500W at 400V. That high-voltage, high-power combo packs serious heat density into a small footprint. And the 300mm length keeps the heated zone tight, so you’re not wasting energy warming up everything around it. Just the spot that matters. The materials do the heavy lifting. Halogen technology keeps the quartz envelope steady even under intense heat, and the internal gas fill shields the filament. The whole design is built to handle rapid on-off cycling without burning out. The R7s connector is a straight-through, double-ended fit, so wiring is quick and the tube runs cleanly end-to-end inside the reflector housing. Mount it on a wall or bracket and you’ve got instant spot heating for production lines, drying stations, or machine enclosures. Warm-up is fast, and the infrared output hits immediately. But keep this in mind: 2500W at 400V means you need a circuit that’s properly spec’d, and you’ll want enough cooling around the housing to keep ambient temperatures in check.
