Reading the two numbers that matter
Neither the operating temperature range nor the IP rating is a class wide property. Two products in one series can differ, so check the listing for the exact item.
On moisture, work from the exact figure, not from the word waterproof. IP20 covers dry interiors and nothing else. IP65 means the product resists jets of water from any direction. IP67 means it withstands temporary immersion. For a cabinet that sees condensation and washdown, the EnoLED 24V Glow67 IP67 wet location strip is one option; read its published rating, output, and stated operating temperature range before you commit (verify all of those on the listing before you rely on them).
Whatever you choose, the rating has to carry the whole assembly. Strip, every joint, both end seals, the cable entry, and the driver in its enclosure each need to suit their environment. A wet location rating on the tape does not protect a dry location connector six inches away.
Even light across every shelf
The visual problem in most coolers is vertical falloff. A single canopy run lights the top shelf well and leaves the bottom in shadow, which shoppers read as empty stock.
Mount a run under the front edge of each shelf, set back behind the price rail and aimed slightly forward. Vertical mullion runs on the door frames suit multi-door line-ups, though they need the same setback discipline so the emitter stays out of the sightline at the glass. Keep one product and one nominal color temperature across the line-up: two output series in adjacent doors read as a color change in the merchandise.
A high output run suits deep cases, since the glazing takes its share. One option is the LEDClub 24V SMD 400 Series; check its lumens per foot, watts per foot, CRI, voltage, cut interval, rating, and temperature range for the position (each of those needs verifying before you rely on them). Browse the wider LED strip light collection to compare formats, chosen per product on output, viewing distance, channel depth, diffuser, and LED density.
Color rendering and how the product looks on the shelf
Packaging, produce, and printed labels all shift under a low rendering source. A high CRI product keeps those appearances closer to daylight, which is why CRI is worth reading off the page rather than inferring from a series name.
Color temperature follows the merchandise and the rest of the store. Cooler settings suit chilled and frozen sections in many layouts, warmer settings suit deli and bakery counters, and a mismatch between the case and the aisle above it shows from a few feet away. Our guide to bakery and deli display case lighting covers the warm counter side.
Power, wiring, and getting the case serviced
Work the load out case by case: installed feet times the published watts per foot, then pick a driver holding at least 20 percent current headroom above that number (verify the current guidance). Match voltage exactly: 24V tape on a 24V driver, never crossed. Shelf runs and mullions return in parallel rather than chained in series, so the far door does not sit dimmer than the first.
Strips still generate heat while running, even in a cold cabinet, and an aluminum profile inside a shelf rail helps dissipate it while protecting the tape from carts and restocking. No cabinet requires one. A profile reduces visible dotting without guaranteeing it disappears, since dot appearance tracks LED density, profile depth, and diffuser too.
Leave the mains supply, hardwired drivers, junction boxes, and fixed switching to a licensed electrician, who follows the manufacturer instructions, local code, and the NEC. Case manufacturers publish their own service instructions, which govern anything inside their cabinet.
