InteGrade engine UB Vi 1150 mm 940 PW G4 is a fourth-generation linear LED engine from the Premium White series, equipped with Uniform Beam optics designed for mounting in the upper part of refrigerated furniture (category “For canopy lighting”). Power of 18.6 W with a luminous flux of 1896 lm and a color temperature of 4000 K (940 — neutral white) delivers intense, clean light that highlights the natural color of products across the entire height of the fixture. The Premium White range stands out with an exceptional CRI of 94 and excellent color consistency of 3 SDCM, creating a uniform, professional look for the display along the full length of the refrigerated unit.

Key features and benefits

• Premium White — the highest light quality in the G4 family — specially formulated Premium White LEDs provide dazzling clean white light and vivid, saturated colors; fish, seafood, dairy and ready meals look natural and appetizing, boosting customer purchase decisions.
• 3 SDCM color consistency — a distinguishing feature of the PW series: color deviations between adjacent engines are practically imperceptible to the naked eye; the display appears uniform and professional even in large multi-unit installations.
• CRI 94 (typical) — the highest color rendering in the G4 family; natural, faithful product colors increase customer trust in product quality and reduce disappointment after purchase.
• Color temperature 940 (4000 K — neutral white) — a clean, cool white that excellently highlights fish, seafood, dairy, ready meals and light-packaged products; it emphasizes freshness and hygiene of the display, encouraging customers to reach for the products.

• Vi (vision) version — maximum luminous flux — 1896 lm at 18.6 W provides exceptional brightness and product visibility even through glass refrigerator doors; the merchandise attracts customers from a distance.
• Efficiency up to 137 lm/W (G4 system) — state-of-the-art G4 system efficiency lowers operating costs while delivering top-quality light.
• Continuous light line without hot spots and glare — revolutionary G4 optics eliminate dazzling bright spots and reflections on packaging; the display looks uniform across the full 1150 mm length.
• Instant full light — no warm-up time, full brightness from the first second every time it is switched on; reliable operation during multiple daily cycles.
• 50,000 h lifetime — at 16 hours of operation per day, more than 8 years without replacement; minimal lumen depreciation and color shift over time.

FAQ — most frequently asked questions

How does this engine (940) differ from the 930 PW G4 version of the same length?

For 1150 mm length in the upper part of the fixture, two PW Vi variants are available: 940 PW G4 (this product, 10NC: 9290 021 608, 18.6 W, 1896 lm) and 930 PW G4 (10NC: 9290 021 607, 19.0 W, 1738 lm). Both have CRI 94 and 3 SDCM color consistency. The difference is the color temperature: 940 (4000 K — neutral white) works better for fish, seafood, dairy and ready meals. 930 (3000 K — warm white) is a better choice for meat, cold cuts, cheeses and bread. The choice should be matched to the assortment of the specific refrigerated fixture.

How does the Premium White (PW) series differ from WWR and standard series?

The Premium White (PW) series offers CRI 94 and 3 SDCM color consistency — better than the standard series (CRI 90–92, 5 SDCM) and WWR (CRI 90, 5 SDCM). Additionally, PW enables a uniform lighting appearance throughout the store when combined with Philips Fortimo SLM Premium White spotlights. WWR is dedicated to enhancing warm tones of food products (especially meat and cold cuts) thanks to its special LED formulation.

How does the Vi (vision) version differ from Va (value) for UB 1150mm 940 PW G4?

The Vi (vision) version delivers 1896 lm at 18.6 W — designed for deeper fixtures and demanding applications where the product must be clearly visible through glass doors. The Va (value) version of the same engine offers a lower flux at significantly lower power — chosen where energy savings are a priority.

Which LED driver is required?

The engine requires a constant voltage 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 a combination guarantees the 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, which is confirmed by the product label. NSF and UL 2108 certifications allow use inside refrigerated and frozen furniture 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 ready-made fixture?

Engine is an LED module without an external enclosure, intended for direct OEM integration into refrigerated furniture construction. Fixture (F) is a complete luminaire with an enclosure, ready for installation on standard InteGrade profiles. The Vi UB engine is chosen by refrigerated furniture manufacturers who integrate the LED module directly into the upper part of the unit.

Product intended for OEM applications — requires installation in the structure of refrigerated furniture and connection to a compatible Philips 24 V DC Class 2 driver. The engine is not a standalone ready-to-use luminaire.
