This is a 220mm bare infrared quartz heat bulb rated at 500W, fitted with a standard R7 push-in cap. It is a direct replacement bulb for commercial food warming applications where the existing fitting accepts an R7 cap type. The quartz glass sleeve is a normal feature of this bulb format and is not an additional protective guard.

In a working kitchen, heat lamps over the pass, chip dumps, burger shoots and hot holding stations depend on reliable infrared output to keep plated food at a safe serving temperature between the kitchen and front-of-house. A failed bulb in that position disrupts service and risks food safety compliance. Having a supply of correctly specified replacement bulbs on hand avoids that disruption.

The R7 cap is one of the most widely used fittings in catering heat lamp equipment, which makes this bulb compatible with a broad range of pass lamps and food warming units already in circulation. Key practical points include:

  • Push-in R7 fitting for straightforward replacement
  • Quartz glass construction suitable for the heat and humidity of a working kitchen environment
  • Infrared output focused on food surface warming rather than ambient air heating
  • Compact 220mm format fits standard lamp housings designed for this bulb length

Before purchasing, confirm that your existing lamp housing is rated for 500W and accepts the 220mm R7 format specifically — lamp housings vary and not all accept this bulb length or wattage. If you are unsure of the correct specification for your equipment, it is worth checking the lamp unit's documentation or the original bulb markings before ordering.

This bulb is suited to any commercial kitchen or front-of-house operation using heat lamp equipment for pass service, chip and fried food holding, or similar food warming duties. If your operation runs multiple high-throughput stations or extended service periods, it may be worth discussing your wider heat lamp setup with us — we are happy to help you identify the right replacement specification.

Frequently asked questions

How do I confirm this bulb is compatible with my heat lamp fitting?

Check the cap type and bulb length marked on your existing bulb or lamp housing documentation. This bulb uses an R7 push-in cap and measures 220mm in length — both need to match your fitting exactly. If the markings on your current bulb are unclear, the lamp unit's manual or manufacturer plate will usually confirm the required specification.

Is 500W the right wattage for a food pass or chip dump application?

500W is a common wattage for single-bulb pass lamps and chip dump heat lamps in most commercial kitchens. However, the correct wattage depends on your specific lamp housing — fitting a higher-wattage bulb than the unit is rated for is a safety risk. Always match the replacement wattage to what is specified for your equipment rather than assuming a higher wattage will perform better.

How often should heat lamp bulbs be replaced in a busy kitchen?

Bulb life varies depending on how frequently the lamp is switched on and off, the ambient conditions, and the quality of the fitting. In a high-volume kitchen where heat lamps are in use throughout service, it is practical to keep a small stock of replacement bulbs on hand so a failed bulb can be swapped quickly without interrupting service.
