Luminous efficacy for our standard hardwired under cabinet lines consistently achieves 110-120 lumens per watt at 3000K and 4000K color temperatures under real-world operating conditions. This high efficacy is realized through the use of premium Samsung LM301H or Epistar 2835 LED chips mounted on thermally optimized aluminum PCBs, coupled with our proprietary constant current drivers featuring 92-94% efficiency. System efficacy measurements strictly adhere to IES LM-79 testing protocols, accounting for all optical and driver losses, ensuring the published lumen output and wattage values reflect actual installed performance without inflated theoretical figures.
Color rendering is a critical focus for kitchen and task lighting applications. All hardwired under cabinet models targeting premium markets utilize LED bins specifically selected to guarantee a minimum CRI (Ra) of 92, with R9 values consistently exceeding 50. We further validate performance using TM-30-15 metrics, achieving Rf values of 92+ and Rg values near 100, ensuring accurate and vibrant representation of all colors, particularly critical for food preparation and presentation. This high-fidelity color rendering is maintained across the entire production batch through our rigorous in-line binning and post-assembly spectrophotometric verification process, eliminating batch-to-batch variation.
Regarding environmental protection, standard hardwired under cabinet lighting from Beauty STC carries an IP20 rating, suitable for dry indoor locations as per NEC Article 410. For installations requiring resistance to moisture splashes near sinks or in high-humidity environments, we offer specific models rated IP54. This rating signifies protection against dust ingress sufficient to prevent harmful deposits and resistance to water splashes from any direction, achieved through sealed driver compartments and gasketed lens joints. It is essential to note that IP54 is the practical maximum for under-cabinet applications; higher ratings like IP65 are generally unnecessary and can compromise optical clarity and thermal management in this specific fixture type. All IP ratings are validated through third-party testing to IEC 60529 standards.
Beauty STC’s commitment to quality is embedded in every aspect of these hardwired systems. We utilize 6063-T5 aluminum extrusions with a minimum wall thickness of 1.8mm for superior heat dissipation, directly contributing to the rated 50,000-hour L90 lifetime at 25°C ambient. Our custom-wound transformers employ high-temperature class H components and feature robust over-temperature, short-circuit, and open-load protection. Rigorous 100% in-circuit testing of drivers and 100% photometric and color verification of finished fixtures ensure compliance with specifications. All products undergo extended burn-in and thermal stress testing, carry UL/cUL Wet Location Listing for applicable models, and support smooth 0-10V dimming down to 1% without flicker. This comprehensive approach to engineering and quality control guarantees reliable, high-performance illumination that maintains its lumen output and color fidelity throughout its service life, distinguishing Beauty STC products in the professional lighting market.
