Philips InteGrade engine NB Va 1430 mm 940 PW G4 — Premium White LED engine for refrigerated display case doors

InteGrade engine NB Va 1430 mm 940 PW G4 is an energy-efficient fourth-generation linear LED engine from the Premium White series, equipped with Narrow Beam optics designed for installation in the doors and frames of refrigerated display case furniture (category “For chillers with doors”). At only 10.7 W and 24 V DC, it delivers 1195 lm of precisely directed light at a 4000 K (neutral white) color temperature. The exceptional CRI of 94 and color consistency of 3 SDCM in the Premium White series ensure a uniform, professional display appearance that builds a premium store image.

Key features and benefits

• Premium White — the highest light quality in the G4 family — specially formulated Premium White LEDs deliver pure white light and vivid, saturated colors; fish, dairy, seafood and prepared foods look natural and appetizing, directly influencing customer purchase decisions.
• 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 uniform and luxurious 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 and reduce disappointment after purchase.
• 940 color temperature (4000 K — neutral white) — clean, cool white light perfectly highlights fish, seafood, dairy and prepared foods; it emphasizes freshness and hygiene of the display.
• One consistent appearance for the entire store — Premium White InteGrade G4 can be combined with Philips Fortimo SLM Premium White spotlights; the same color temperature and light quality throughout the store enhances brand image.
• Narrow Beam (NB) optics — precise product lighting — according to Philips classification (“For chillers with doors”), the narrow beam directs light precisely onto the products along the full height of the cabinet; typically mounted vertically in doors, frames or side profiles of the refrigerated display case. Unlike Uniform Beam (UB — upper part of cabinet), NB illuminates the display from the door side, providing excellent product visibility when the door is opened and through the glass.
• Va (value) version — optimized energy efficiency — 10.7 W at 1195 lm is an excellent balance of lighting quality and power consumption; delivers real savings on electricity bills in installations with many refrigerated cabinets.
• 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 and reflections on packaging; the display looks uniform along the full 1430 mm length.
• Instant full brightness — no warm-up time, full light output from the first second of switching on; reliable operation during multiple daily cycles.
• 50,000 h lifetime — more than 8 years at 16 hours a day without replacement; minimal lumen depreciation and color shift over time.
• 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 specific applications is Narrow Beam (NB) optics designed for?

Philips classifies Narrow Beam optics in the “For chillers with doors” category. The narrow beam directs light precisely onto products along the full height of the cabinet — typically mounted vertically in the doors, frames or side profiles of a refrigerated display case with doors. Unlike Uniform Beam (UB — upper cabinet lighting), NB illuminates the display from the door side, providing excellent product visibility when the door is open and through the glass.

What is the difference between the Va (value) and Vi (vision) versions for NB 1430mm 940 PW G4?

The Va (value) version delivers 1195 lm at 10.7 W — optimized for energy efficiency; ideal for standard applications where savings are the priority. The Vi (vision) version offers a higher flux at higher power — intended for installations requiring maximum brightness, such as very deep cabinets or intense ambient lighting in the store.

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 90–92, 5 SDCM) and WWR (CRI 90, 5 SDCM). PW also enables a uniform lighting look throughout the store — especially when combined with Philips Fortimo SLM Premium White spotlights. WWR is dedicated to enhancing warm tones of food products (meat, cold cuts, cheeses) in refrigerated cases.

Which LED driver is required?

The engine requires a 24 V DC Class 2 (SELV) power supply. The product label states: “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 permit 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, designed for direct OEM integration into refrigerated display case furniture construction — doors, frames, side profiles. Fixture (F) is a complete luminaire with housing, ready to mount on standard InteGrade profiles. The NB Va engine is chosen by furniture manufacturers who integrate the LED module directly into the door or frame construction of the cabinet.

This product is intended 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.
