Why this heat bulb earns its place
The jacketed quartz lamp is the safety answer for takeaways, farm shops, bakeries and quick-service kitchens where visible hot food drives sales. Raw quartz infrared lamps work—but if the bulb shatters, glass hits your product. The Oxford Hardware R7 comes jacketed, which means the bulb is enclosed within a protective sheath. If it fails, the jacket contains it. Food stays safe, your insurance stays clean.
At 300 W and 220 mm long, it's a solid mid-size lamp for display cabinets and heated counters. It's the kind of straightforward heat source that fits most commercial display fittings and heats steadily through the rush. The linear design (20 mm diameter) is a standard fit in catering equipment, so it integrates into existing fixtures without refitting. At 50 grammes, it's light enough to handle, but built to the pressure specs quartz needs.
Food outlets benefit from the reliability: a jacketed lamp means zero glass-in-food risk, which is non-negotiable under HACCP. This is the replacement bulb you reach for when the original fails—or the first choice if you're fitting a new display and want to start safely.
