How high should a heat lamp be mounted?

Close enough to hold the surface temperature and far enough not to dry or continue cooking it. The correct distance depends on the plates in use, so an adjustable arm is worth having where plating varies.

How many heat lamps does a pass need?

One per plating position that must be held at the same moment. Count positions rather than measuring bench length, since gaps show up as plates being moved under a lamp instead of plated beneath one.

Can a heat lamp replace a food warmer?

No. A lamp holds a plated surface briefly from above; a food warmer holds prepared food through a service. They solve different parts of the same problem and are usually specified together.

Commercial Heat Lamps Australia | Infrared & Radiant Food Holding Lamps

A commercial or industrial heat lamp holds plated food at the pass for the minutes between plating and service. It works by radiant heat from above, which keeps a surface hot without cooking further, and that short-duration job is what separates it from a cabinet or a bain marie. Food that needs holding for a service period belongs in the broader commercial food warmer range; where cold crockery is the problem, compare commercial plate warmers.

Lamp height above the plate is the setting that decides whether it works. Too high and the surface cools; too low and the food dries or continues to cook. Fixed-height units must be mounted at the right distance for the plates in use, while adjustable arms allow that to be tuned after installation.

Coverage follows the pass. A single food lamp heater serves one plating position; a bar of lamps or a gantry serves a run. Count the positions that need holding at once rather than the length of the bench.

Where a restaurant heating lamp is mounted over a service counter used by guests, guarding and the heat reaching the counter surface matter as much as the food itself.

Choosing the right heat lamps

Key factors to consider before purchasing. Our team can help you find the right fit — call or get a quote anytime.

Capacity & size

Match equipment capacity to your daily output. Consider available floor space and door clearances.

Installation & compliance

Confirm levelling, wall clearance and the access needed for cleaning and service. We can help with kitchen planning.

Compliance & engineering standards

Before comparing heat lamps, confirm how long food waits between plating and service, how many plating positions need covering, and the mounting height available above the pass. Check whether the height can be adjusted after installation.

Look at how lamps are replaced and whether that can be done without dismantling the fixture, how the mount is fixed and rated, and whether guarding is needed where guests or staff pass beneath. Lamps are consumables, so replacement access is a running consideration rather than a detail.

Frequently asked questions

Do heat lamps cook or reheat food?

No. Heat lamps maintain serving temperature only and should not be used for cooking or browning.

Why do foods dry out under heat lamps?

Radiant heat removes surface moisture over time. Correct mounting height and limited holding duration help protect food quality.

Can heat lamps be used front-of-house?

Yes—choose safe-touch housings and softer lighting for FOH or buffet environments.

How many plates can one lamp cover?

Bulb-type lamps typically cover 1–2 plates; strip heaters cover wider pass areas up to 3–4 plates depending on length.

How long can food sit under a heat lamp?

Minutes rather than a service period. Radiant heat holds a plated surface for the short wait before service; food needing longer holding belongs in a cabinet or pan-based unit, because a lamp dries the surface over time.

Minutes, not a service period

Radiant heat holds a plated surface for the short wait between plating and service. Food that must be held for a whole service belongs in a cabinet or a pan-based unit, because a lamp will dry the surface long before the period is over.

Height above the plate

Too high and the food cools; too low and the surface dries or continues cooking. Fixed units must be mounted at the correct distance for the plates in use; adjustable arms let that be corrected after installation, which is worth having where plating varies.

Covering the plating positions

Count the positions that need holding at the same moment rather than measuring the bench. A single lamp covers one plating position; a bar or gantry covers a run. Coverage gaps show up as plates moved under a lamp rather than plated beneath one.
