Philips InteGrade engine Va 1150 mm WWR Shelf G4 — Food LED engine for shelf lighting

InteGrade engine Va 1150 mm WWR Shelf G4 is an energy-efficient fourth-generation linear LED engine designed — according to Philips classification — for shelf lighting in refrigerated cabinets and freezers (category "For shelf lighting"). With merely 5.46 W power and 24 V DC voltage, it delivers 618 lm in Philips Food LED WWR (warm white red) technology — a dedicated LED formula that enhances food product colors. Meat, deli products, cheese, and bread look appetizing and fresh throughout the day, with minimal energy consumption.

Key Features and Benefits

• Philips Food LED technology (WWR — warm white red) — specially formulated LED recipe for food display in refrigerated conditions: enhanced saturation of reds and warm tones while maintaining natural white; products look fresh and appetizing, translating into higher customer engagement and increased sales.
• Exceptionally low power consumption of 5.46 W — the Va (value) version of the G4 generation offers the best ratio of lighting quality to energy consumption; significant savings on electricity bills in installations with multiple refrigerated cabinets.
• Efficacy up to 137 lm/W (G4 system) — state-of-the-art energy efficiency of the G4 generation; more light from less power compared to previous InteGrade generations.
• Continuous line of light without hot spots and glare — revolutionary G4 optics create an uninterrupted, uniform light beam along the entire shelf; no blinding spots and reflections on packaging improve display readability.
• CRI ≥ 90 — natural, faithful color reproduction of food products; customers see the goods as they really are, building trust in display quality.
• Color consistency 5 SDCM — minimal color differences between adjacent engines; uniform lighting appearance across the entire refrigerated shelf.
• Instant full light — no warm-up time, full brightness from the first second at every turn-on; reliable operation with multiple daily cycles.
• Lifespan 50,000 h — minimal degradation of luminous flux and color shift over time; low maintenance costs and rare display downtime.
• Dimmable — flexible control of lighting intensity adapted to time of day and store zone; real energy savings outside peak hours.
• Wide operating temperature range — certified for operation from -30°C to +30°C; reliable performance in both refrigerators and deep-freeze units.
• Full compatibility with InteGrade G4 ecosystem — mounting profiles, clips, power cables, and controllers from the G4 portfolio fit without modification; easy expansion and upgrade of existing installations.

FAQ — Frequently Asked Questions

What does the "Shelf" designation in the product name mean?

The Shelf designation indicates that the engine is designed for shelf lighting — mounting under or in the shelf profile of a refrigerated cabinet, directed at goods on the lower shelf. Philips classifies these products in the "For shelf lighting" category in the InteGrade G4 brochure. This is a different application than engines for the upper part of the cabinet (canopy) or door lighting.

What is the difference between the Va (value) version and Vi (vision) version?

The Va (value) version is optimized for energy efficiency — delivering 618 lm at just 5.46 W, making it an ideal choice where energy savings are a priority. The Vi (vision) version of the same engine offers higher luminous flux at higher power, designed for installations requiring maximum brightness. For shelf lighting, where the engine operates close to the product, the Va version typically fully meets photometric requirements.

What does the Philips Food LED (WWR) technology mean?

WWR is an acronym for warm white red — an LED recipe developed by Philips specifically for food display in refrigerated conditions. It enhances the saturation of reds and warm tones (meat, deli products, cheese, bread) while maintaining natural white. WWR products are dedicated exclusively to refrigerated cabinets and freezers — not for general room lighting.

What LED controller is required?

The engine requires a 24 V DC Class 2 (SELV) constant voltage power supply. The product label states: "Use Only with Class 2 Power unit". Philips certified the system exclusively with Philips Constant Voltage controllers — only this combination activates the 5-year system warranty and guaranteed 50,000 h lifespan.

Is the engine suitable for freezers?

Yes. The product is certified for operation at ambient temperatures from -30°C to +30°C, as confirmed by the product label and NSF and UL 2108 certifications. The engine is designed for use inside refrigerated cabinets and freezers in accordance with 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, designed for direct OEM integration into refrigerated cabinet construction — shelf profile, frame, or dedicated mounting channel. Fixture (F) is a complete luminaire with a housing, ready for mounting on standard InteGrade profiles. The Va Shelf Engine is selected by refrigerated cabinet manufacturers who integrate the LED module directly into the shelf construction.

Product designed for OEM applications — requires mounting in a refrigerated cabinet profile or construction and connection to a compatible Philips 24 V DC Class 2 controller. The engine is not a standalone fixture ready for use.
