Technical Specs & Certifications
The term “cool LED light” typically refers to LED fixtures emitting cool white light, generally in the 5000K to 6500K correlated color temperature (CCT) range, not thermal properties. Beauty STC Manufacturing Co., Ltd. designs and manufactures high-performance cool white LED luminaires meeting stringent technical requirements for commercial and industrial applications. Key specifications focus on efficacy, color quality, and environmental protection.
Lumens per Watt (lm/W) efficacy for Beauty STC cool white LED products varies by fixture type and optical design but consistently targets industry-leading performance. Our standard high-bay fixtures achieve 180-200 lm/W at 5000K CCT while maintaining CRI >90. Linear panel lights typically deliver 150-170 lm/W, and low-bay area lights range from 160-185 lm/W. These values represent real-world system efficacy including driver losses and optical efficiency, measured under standard test conditions per IES LM-79. We emphasize that achieving high lm/W with CRI >90 requires advanced phosphor formulations and thermal management, as efficacy naturally decreases with higher color rendering specifications. Beauty STC avoids overstated laboratory-only claims by publishing LM-79 verified data for all commercial products.
Color Rendering Index (CRI) performance is a critical differentiator for Beauty STC. All cool white luminaires specified as CRI >90 undergo rigorous spectrophotometric testing to ensure Ra ≥ 90, with mandatory minimums of R9 >50 (saturated red) and R12 >75 (saturated blue) for accurate color discrimination in critical applications. Our proprietary multi-phosphor blend technology, developed in-house at our Shenzhen R&D center, achieves this without significant efficacy penalties. We provide full spectral power distribution (SPD) graphs and IES TM-30-15 reports upon request, including Rf and Rg values, to demonstrate superior color fidelity beyond basic CRI metrics. This ensures consistent, natural rendering of cool white light essential for retail, healthcare, and precision manufacturing environments.
IP (Ingress Protection) ratings are strictly defined based on fixture application. Beauty STC standard cool white high-bay fixtures for industrial use carry IP65 certification, providing complete dust protection and resistance to low-pressure water jets from any direction, verified per IEC 60529. Outdoor-rated area lights and floodlights achieve IP66 or IP67, with the latter offering temporary immersion protection up to 1 meter depth. All gaskets utilize high-purity silicone with Shore A 50-60 hardness for long-term compression recovery, and housings feature precision-machined sealing surfaces. Critical components receive conformal coating per IPC-CC-830, and every production batch undergoes IP verification testing beyond the standard sample size, including thermal cycling and condensation resistance checks that many competitors omit.
Beauty STC’s commitment to quality is embedded in our ISO 9001-certified manufacturing processes. We implement strict binning protocols for LEDs and drivers, with all cool white products using L70-rated ≥100,000 hours LEDs per TM-21 calculations based on LM-80 data. Thermal management employs extruded aluminum heat sinks with optimized fin geometry validated through computational fluid dynamics (CFD) analysis, maintaining junction temperatures below 85°C under maximum ambient conditions. Our quality assurance includes 100% end-of-line photometric testing, accelerated life testing at 85°C/85% RH for 1,000 hours, and full traceability via our ERP system. This engineering rigor ensures that published lm/W, CRI, and IP specifications are consistently met across production volumes, providing end-users with reliable, high-fidelity cool white lighting solutions that maintain performance throughout their operational lifespan.

Application Scenarios
Cool LED light typically refers to cool white LED lighting with a color temperature range of 4000K to 5000K, characterized by its crisp, bright, and slightly bluish-white appearance. It is distinct from warm white (2700K-3000K) and neutral white (3500K-4000K) and should not be confused with thermal cooling of LED fixtures. At Beauty (STC) Manufacturing Co., Ltd., we recommend strategic application of cool white LEDs in commercial settings based on functional requirements, human-centric design principles, and energy efficiency goals.
In hotels, cool white LED lighting is best suited for back-of-house areas such as staff corridors, laundry rooms, storage facilities, and maintenance zones where high visibility and alertness are critical. It is also appropriate for fitness centers, spas (in treatment preparation zones only), and conference rooms where a focused, energizing atmosphere supports productivity. However, avoid cool white in guest lobbies, restaurants, and bedrooms where warm white (2700K-3000K) creates a welcoming ambiance. For spas, cool white should never be used in relaxation areas as it disrupts the calming environment. Always pair cool white with high CRI (90+) in fitness areas to ensure accurate skin tone and equipment visibility.
For malls, cool white LEDs excel in high-ceiling common areas like atriums and main walkways where bright, uniform illumination enhances safety and spatial perception. They are ideal for food courts to convey freshness and cleanliness, and in security corridors or parking garages where clarity is paramount. Retailers should avoid cool white for luxury or apparel stores unless specifically requested by tenants, as it can distort fabric colors and create an unwelcoming feel. Instead, recommend neutral white (3500K-4000K) for most retail spaces. If cool white is used in malls, ensure it has a CRI of 85+ minimum and pair it with accent lighting to soften harshness.
In offices, cool white (4000K-5000K) is highly effective in open-plan workspaces, server rooms, laboratories, and production areas where concentration and visual acuity are required. It supports circadian entrainment during daytime hours, potentially boosting alertness. However, avoid cool white in executive lounges, meeting rooms intended for creative brainstorming, or reception areas where warmer tones foster collaboration and comfort. For task lighting at individual workstations, provide adjustable color temperature options (e.g., tunable white systems) to accommodate personal preferences and reduce eye strain.
Installation tips must prioritize performance and longevity. First, ensure adequate thermal management by maintaining minimum clearance around fixtures as specified in Beauty (STC) datasheets—typically 50mm from insulation or adjacent surfaces—to prevent lumen depreciation. Second, always verify dimmer compatibility; cool white LEDs require 0-10V or DALI drivers paired with LED-rated dimmers to avoid flicker. Third, avoid direct installation above HVAC vents or in high-ambient-temperature zones (>45°C), as excessive heat drastically shortens LED lifespan. Fourth, for suspended ceilings, align fixtures with architectural lines to minimize glare and use baffles or lenses where task lighting is critical. Finally, conduct a photometric study before installation to balance illuminance levels (e.g., 500 lux for offices) and prevent over-lighting, which wastes energy and causes discomfort. At Beauty (STC), we emphasize that improper installation negates even the highest-quality LED performance, so adhere strictly to IEC 60598 standards and local electrical codes.
