What CRI and color temperature do you recommend for different retail zones?

General aisles: CRI 80+, 4000K (neutral white, energy-efficient). Fresh produce & deli: CRI 90+, 3500K (warm white, enhanced red spectrum R9 ≥ 50 for food color rendering). Bakery & prepared foods: CRI 90+, 2700K–3000K (warm, appetizing). Refrigerator cases: CRI 80+, 4000K, cold-storage rated. Clothing retail: CRI 90+, 3500K–4000K (accurate color rendering for garment selection).

How do you ensure color consistency across multiple store locations?

We implement MacAdam ellipse binning (within 3-step SDCM) for all retail supply agreements. This means every tube in every batch is within 3 MacAdam steps of your specified color point — visually indistinguishable to the human eye. We also maintain a batch archive so reorder batches can be matched to your original specification.

Can your tubes handle the temperature cycling in refrigerator display cases?

Yes. Our cold-storage rated T8 tubes are specifically engineered for refrigerator and freezer display cases. They feature: anti-condensation housing, cold-start rated driver (operates at -20°C), IP44 moisture protection, and thermal management designed for the temperature cycling (-20°C to +40°C) typical of display case environments. L70 lifespan ≥ 40,000h in cold storage conditions.

Do you offer a chain-wide supply agreement with specification lock?

Yes. Our retail chain supply agreements include: guaranteed color temperature (±150K) and CRI (±2 points) consistency across all batches, specification lock for the duration of the agreement, priority production scheduling, and a dedicated account manager. We currently supply LED products to retail chains in 12 countries.

Why Retail Chains Choose Cornea Lighting?

Enhanced Red-Spectrum for Food Display

R9 ≥ 50

Our food-retail T8 tubes feature an enhanced red spectrum (R9 ≥ 50) that makes fresh produce, meat, and bakery items look more vibrant and appetizing. Studies show high-CRI lighting increases fresh food purchase intent by 15–20%.

Cold Storage Rated (-20°C to +40°C)

IP44 · -20°C rated

Specifically engineered for refrigerator and freezer display cases. Anti-condensation housing, cold-start rated driver, and IP44 rating ensure reliable operation in cold storage environments without flickering or premature failure.
