Philips InteGrade engine UB Vi 1150 mm 930 PW G4 — Premium White LED engine for the upper part of refrigerated display case furniture

InteGrade engine UB Vi 1150 mm 930 PW G4 is a fourth-generation linear LED engine from the Premium White series, equipped with Uniform Beam optics designed for installation in the upper part of refrigerated display case furniture (Philips category “For canopy lighting”). The 19.0 W power with a 1738 lm luminous flux and 3000 K (930 — warm white) color temperature delivers intense, warm lighting that highlights the natural color of food products across the full height of the cabinet. The Premium White series stands out with an exceptional CRI of 94 and excellent color consistency of 3 SDCM, creating a uniform, luxurious display appearance.

Key features and benefits

• Premium White — the highest light quality in the G4 family — specially formulated Premium White LEDs deliver brilliant pure white light and vivid, saturated colors; meat, cold cuts, cheeses, fruits and vegetables look natural and appetizing, attracting customers' attention.
• 3 SDCM color consistency — a standout feature of the PW series: color differences between neighboring engines are practically invisible to the naked eye; the display looks homogeneous and professional even in large multi-cabinet installations.
• CRI 94 (typical) — the highest color rendering index in the G4 family; natural, faithful product colors strengthen customer trust in product quality.
• 930 color temperature (3000 K — warm white) — warm, cozy light ideal for displaying meat, cold cuts, cheeses, bread and fruits; it gives products an appetizing, inviting appearance and creates a welcoming shopping atmosphere.
• One consistent appearance for the entire store — Premium White InteGrade G4 can be combined with Philips Fortimo SLM Premium White spotlights; the same light quality throughout the store enhances brand image and provides a consistent customer experience.
• Uniform Beam (UB) optics — even lighting from top to bottom — according to Philips classification (“For canopy lighting”), the advanced optical system evenly illuminates the full height of the interior from the top section to the bottom shelf; it eliminates dark zones in the center of glass door cabinets.
• Vi (vision) version — maximum luminous flux — 1738 lm at 19.0 W provides exceptional brightness and product visibility even through glass refrigerator doors.
• Up to 137 lm/W efficiency (G4 system) — state-of-the-art G4 generation efficiency reduces operating costs while delivering top light quality.
• Continuous light line without hot spots or glare — advanced G4 optics eliminate dazzling bright points, reflections on packaging and dark areas; the display looks uniform along the entire length of the shelf.
• Instant full brightness — no warm-up time, full light output from the first second of switching on; reliable operation during multiple daily on/off cycles.
• 50,000 h lifetime — minimal lumen depreciation and color shift over time; more than 8 years of operation at 16 hours per day without replacement.
• Dimmable — flexible brightness adjustment for time of day and store zone; energy savings outside peak hours.
• Full compatibility with the InteGrade G4 ecosystem — mounting profiles, clips, power cables and drivers from the G4 portfolio fit without modification; easy expansion and modernization of existing installations.

FAQ — frequently asked questions

What is the difference between 930 and 940 color temperature in the Premium White series?

Both variants belong to the Premium White series and feature CRI 94 and 3 SDCM consistency. The difference is in color temperature: 930 (3000 K — warm white) delivers warm, cozy light ideal for meat, cold cuts, cheeses and bread — products that look better in warmer light. 940 (4000 K — neutral white) provides cooler, cleaner light that works better for fish, seafood, dairy and prepared foods. The choice should be matched to the assortment of the specific refrigerated display case.

What is the difference between the Premium White (PW) series and the standard or WWR series?

The Premium White (PW) series offers CRI 94 and 3 SDCM consistency — better than the standard series (CRI 90, 5 SDCM) and WWR (CRI 90, 5 SDCM). WWR (warm white red) is dedicated to enhancing the colors of food products in refrigerated cases (special LED formula). PW, on the other hand, delivers the highest color reproduction quality and enables a uniform lighting look throughout the store — especially when combined with Philips Fortimo SLM PW spotlights.

What is the difference between the Vi (vision) and Va (value) versions for UB 1150mm 930 PW G4?

The Vi (vision) version delivers 1738 lm at 19.0 W — intended for deeper cabinets and demanding applications where products need to be clearly visible through glass doors. The Va (value) version of the same engine offers lower flux at significantly lower power — chosen when energy savings are prioritized in smaller cabinets.

Which LED driver is required?

The engine requires a 24 V DC Class 2 (SELV) power supply. The product label indicates: “Use Only with Class 2 Power unit”. Philips has certified the system only in combination with Philips Constant Voltage drivers — only such pairing ensures 50,000 h lifetime.

Is the engine suitable for freezers?

Yes. The product is certified for operation in ambient temperatures from -30°C to +30°C, as confirmed by the product label. NSF and UL 2108 certifications confirm suitability for use inside refrigerated and freezer cabinets according to IEC/EN 60335-2-24 and IEC/EN 60335-2-89 standards.

What is an LED engine and how does it differ from a finished fixture?

Engine is an LED module without an external housing, intended for direct OEM integration into refrigerated display case furniture. Fixture (F) is a complete luminaire with an external housing, ready to mount on standard InteGrade profiles. The UB Vi engine is selected by manufacturers who integrate the LED module directly into the upper part of the cabinet.

This product is designed for OEM applications — it requires installation into refrigerated display case furniture construction and connection to a compatible Philips 24 V DC Class 2 driver. The engine is not a standalone ready-to-use luminaire.
