Food Heat Lamps for Delis & Sandwich Shops: Streamline Service
Short answer: a deli counter needs 250 W over each 600×400 mm holding zone, mounted 30–45 cm above the food, running 8–12 hours a day at about $0.04 per hour. Two lamps cover a typical 1.2 m sandwich display. See mounting and wattage options in our heat lamp range.
What a deli actually needs from a lamp
A deli counter is a retail surface with a service constraint: food sits in view of the customer, gets handled repeatedly, and has to look good for hours. That makes three demands on the lamp — even coverage without a hot spot, no visible glare into the customer's eyes, and a housing that can be wiped down between customers.
Holding-zone maths for a sandwich case
Measure the case, not the lamp. A 1.2 m display is roughly 1,200×500 mm, which is about 0.6 m². At 250 W per 0.25 m² that is two heads, spaced evenly so the join between them does not create a cold strip. One 500 W lamp in the centre would overheat the middle and leave both ends cool.
Crisp versus moist: where lamps beat chafers
A deli sells texture as much as temperature. Breaded chicken, pasties and pies lose their crust in a chafer within 10–15 minutes because the water pan puts steam against the surface. A lamp keeps the surface dry, so the crust survives 25–40 minutes — long enough for a lunch rush, short enough that you still need to rotate stock.
Cleaning and allergen control on an open counter
An open display collects crumbs and flour dust on the reflector, and a greasy reflector noticeably reduces downward output. Wipe it daily with a damp cloth and pH-neutral detergent, never a spray directed at the housing. Between products, wipe the counter rather than the lamp, and keep tongs in a holder so the same utensil does not cross between fillings.
Deli station sizing
| Display | Lamps needed | Wattage | Height |
| Sandwich / wrap case, 1.2 m | 2 | 250 W each | 30–45 cm |
| Hot counter, 1.8 m | 3 | 250 W each | 30–45 cm |
| Soup and pie pass | 1–2 | 150–250 W | 25–35 cm |
| Carvery joint | 2 | 2 × 250 W | 40–50 cm |
Bulb choice for retail display
A clear bulb shows food colour honestly, which suits sandwiches and salads; a red-tinted bulb flatters cooked meat but makes pale fillings look grey. Whatever the tint, keep the wattage the same — colour changes the look, not the heat.
Cleaning routine for a deli lamp
Switch off and let the housing cool for 15 minutes. Wipe the reflector with a damp cloth and a pH-neutral detergent. Do not spray cleaner onto the housing; moisture gets into the socket and the lamp fails weeks later. Once a week, check the bulb seat for looseness and look at the cord where it leaves the housing — both faults are visible before they become failures.
Queue time is part of the specification
A deli counter is a queue in front of a display. If the lamp is mounted so low that staff must duck to reach the case, every sandwich costs two extra seconds and the lunch line compounds it. Keep the lowest edge of the housing above eye level for the customer and clear of the server arm path, then confirm the food still reads 60–70°C at the surface. Height, coverage and reach are one decision, not three.
Frequently Asked Questions
Do heat lamps dry out sandwiches?
They dry the exposed cut surfaces within 20–30 minutes. Wrap cut faces or hold assembled sandwiches no longer than that under direct lamp heat.
How high should the lamp be over a deli counter?
30–45 cm for 250 W. Higher and the surface cools; lower and the bread dries and the risk of a burn rises.
Can I leave the lamps on all day?
Yes, but run them only while the case is stocked. An empty lit counter wastes about $0.04 per hour per lamp and shortens bulb life for nothing.
What bulb suits a deli counter?
A 250 W infrared E27 bulb. Red-tinted bulbs look warmer over cooked meats; clear bulbs show food colour more honestly.
Is a heat lamp cheaper than a heated display case?
Per hour, yes — about $0.04 against $0.15–0.30 for a heated case. A case holds temperature more evenly, so the choice depends on hold time.
