Food Heat Preservation Lamp Key benefits — why you need it Keeps food at serving temperature: a 290 mm diameter lampshade concentrates heat over a wide area so you can maintain consistent temperature across most dishes without worrying about a too-small lamp. Durable, long-lasting operation: the high-elastic spiral wire is engineered to withstand heavy use — it can stretch about 10 million times and offers a much longer service life than inferior wires. Flexible positioning for any setup: the lamp uses a telescopic (scroll) adjustment knob that lets you freely set the stretching length between 60–180 cm to suit counters, buffet lines, or pass-throughs. Easy, safe control: the gear-type shift switch provides simple, reliable operation while maintaining a clean, professional appearance. Features and performance Lampshade diameter: 290 mm — sized to meet thermal needs of most foods. High-elastic spiral wire: built for repeated extension and retraction (approx. 10 million cycles), improving reliability and reducing downtime. Telescopic adjustment knob (scroll design): smooth, stepless stretching control with an adjustable range of 60–180 cm for precise heat positioning. Gear-type shift switch: secure, convenient switching that fits professional foodservice environments. Compatibility and use Designed for food heat preservation tasks in restaurants, catering, buffet lines, and similar foodservice applications. Works well with plates, chafing dishes, carving stations, and pass-through counters where controlled overhead heat is required. Suitable for both permanent install positions and mobile setups where flexible reach and durability are important. Practical use scenarios Restaurant pass: Mount the lamp above a pass-through to keep plated dishes warm while they wait for pickup, using the telescopic adjustment to set the ideal distance for different menu items. Buffet or catering line: Use the wide 290 mm lampshade to cover chafing dishes and serving trays; adjust height from 60 to 180 cm to accommodate different station layouts. Catering and mobile service: Durable spiral wire and gear-type switch provide reliable, repeatable performance on off-site events where frequent setup and breakdown are required.
