What lights can I use in a walk-in cooler or freezer?

Use LEDs rated for cold, damp service. The Promolux tubes we stock carry IP54 and IP65 ratings and are built for continuous refrigerated operation, unlike standard fluorescent or shop LEDs which dim and fail early in the cold.

Will these LED tubes fit my existing fixtures?

Usually, yes. The Plug-N-Play T8 tubes work as a drop-in replacement for T8 fluorescents on an electronic ballast with no wiring changes, and also run on direct line voltage. Send the fixture length and a photo if you are unsure.

What is the difference between the DTube and the Slimline Bar?

The DTube is a 5ft door tube that installs into door frames and mullions, rated IP65 for wash-down areas. The Slimline Bar is a 4ft canopy light that connects in series up to 150W, rated IP65, for lighting over open cases.

Why is food-safe LED lighting worth paying for?

Ordinary lighting pushes heat and UV onto the product, fading colour and shortening shelf life. Food-safe LEDs are tuned to light the product without cooking it, which protects both the look of the case and what you can sell out of it.

Do you sell the drivers and mounting parts separately?

Yes. The 24V driver, magnetic canopy clips and Molex power cords are all stocked as individual line items so you can order only the piece that failed.

How fast does lighting ship?

Promolux lighting typically ships within two business days.

LED Lighting for Refrigerated Display Cases

Food-safe LED lighting for walk-in coolers, freezers and refrigerated display cases, including Promolux door and canopy tubes.

Cooler lighting does two jobs at once: it sells the product behind the glass and it has to survive the cold and damp doing it. These are LED walk-in cooler and freezer lights built for refrigerated service, not repurposed shop fixtures.

Food-safe by design. The Promolux line is engineered for merchandising fresh food, protecting colour and shelf life rather than fading it the way ordinary lighting does. It is the reason these tubes are specified for meat, deli, dairy and produce cases.

Retrofits what you already have. The Plug-N-Play T8 tubes drop into existing T8 ballasts with no rewiring, or run on line voltage as a type-B LED. The DTube and Slimline Bar mount into door frames and mullions on pre-installed end brackets or spring clips, so most upgrades are a swap rather than a rebuild.

Walk-in cooler light fixtures and the parts around them. Alongside the tubes we stock the 24V driver, canopy clips and Molex power cords, so a lighting job does not stall waiting on the one small part nobody listed.

Not sure which tube length or colour temperature you need? Send the case make and model, or a photo of the existing fixture, and we will match it.
