Technical Specs & Certifications
Beauty STC Group manufactures high-performance 4-inch recessed LED downlights designed to meet stringent architectural and performance demands, though it is important to clarify that “Halo” is a registered trademark of Eaton Corporation for their specific product line. Our equivalent 4-inch recessed lighting solutions, such as the BX4 Series, are engineered to exceed industry benchmarks for efficiency, color quality, and durability.
Lumen output and efficacy are critical metrics for energy-conscious projects. Our standard 4-inch recessed LED downlights deliver 750–900 lumens at typical power draws of 6.5–8.0 watts, achieving efficacies of 110–130 lumens per watt. This performance is validated under LM-79 testing at 25°C ambient conditions and accounts for real-world thermal management. Efficacy remains stable across voltage fluctuations (120–277V AC) due to our integrated constant-current drivers, ensuring consistent light output without lumen depreciation under standard operating conditions.
Color rendering is a priority in our design philosophy. All current-production 4-inch models feature a minimum CRI of 92, with R9 (saturated red) values exceeding 50, as measured per ANSI C78.377 standards. This exceeds the CRI >90 requirement and ensures accurate representation of skin tones, textiles, and artwork in retail, hospitality, and residential settings. We achieve this through rigorously selected phosphor blends and binning protocols that maintain chromaticity within a 3-step MacAdam ellipse (SDCM ≤3) for uniformity across installations.
For environmental protection, our standard 4-inch recessed trims carry an IP44 rating, safeguarding against solid objects larger than 1mm and water splashes from any direction. This makes them suitable for damp locations such as bathrooms, covered porches, and commercial kitchens per NEC/CEC guidelines. For specialized applications requiring higher ingress protection, we offer optional IP65-rated airtight housings with gasketed trims, tested to IEC 60529 standards for dust and low-pressure water jets.
Beauty STC’s quality differentiation lies in our holistic engineering approach. We utilize die-cast aluminum housings with integrated heat sinks to maintain junction temperatures below 85°C, directly contributing to L70 lifespans exceeding 50,000 hours. Every unit undergoes 100% photometric and electrical validation, including in-situ thermal imaging during burn-in. Our drivers are Meanwell-sourced or equivalent, featuring 0–10V dimming compatibility down to 1% with no audible noise. Finish durability is ensured through electrostatic powder coating resistant to chipping and corrosion, while rigorous in-house testing includes 1,000-hour salt-spray exposure for coastal installations. This commitment to precision manufacturing is backed by a 5-year warranty covering both LED and driver components, reflecting our confidence in field reliability.

Application Scenarios
As a Senior LED Lighting Engineer at Beauty (STC) Manufacturing Co., Ltd., I must clarify that Halo is a brand owned by Eaton Corporation, not STC. STC focuses on its own proprietary LED lighting solutions. However, I can provide expert guidance on the application and installation of 4-inch recessed LED downlights, which align with industry standards applicable to products like Halo or STC’s equivalent offerings. This information is based on universal lighting engineering principles for commercial spaces.
In hotel environments, 4-inch recessed downlights excel in guest room corridors where ceiling grids often align with this size, providing uniform ambient illumination without overwhelming the space. They are ideal for bathroom vanities when selected with appropriate damp-rated trims and high CRI values to ensure accurate color rendering for grooming. In restaurant areas within hotels, these fixtures work well for general lighting in banquet halls or cafes, though accent lighting for dining tables typically requires directional pendants. Lobbies benefit from their use in coffered ceilings or soffits to create layered lighting effects, but main atrium spaces usually demand larger fixtures for adequate lumen output.
For mall applications, 4-inch recessed fixtures are most effective in back-of-house areas like staff rooms, restrooms, and administrative offices where standard ceiling grids exist. They serve well in mall corridors as supplementary ambient lighting between larger cove or linear systems, particularly where ceiling obstructions limit fixture size. However, they are generally unsuitable for primary sales floor lighting due to insufficient lumen packages and beam spread for high-ceiling retail environments; larger 6-inch fixtures or dedicated track lighting are preferred for merchandise highlighting. Specialty retail kiosks with standard drop ceilings may utilize them for basic illumination.
In office settings, 4-inch recessed downlights are optimal for private offices, conference rooms, and open-plan workspaces with standard 2×2 or 2×4 ceiling grids. Their size matches common tile layouts, enabling even light distribution that minimizes shadows on work surfaces. Select fixtures with 3500K-4000K CCT and 90+ CRI to support visual tasks and reduce eye strain. Avoid placing them directly over workstations in open offices—instead, align them between desks to prevent screen glare. They are less suitable for high-bay warehouse areas but work well in executive suites where lower light levels are acceptable.
Critical installation considerations begin with verifying the fixture’s IC-rated (Insulation Contact) status before installation in insulated ceilings; non-IC fixtures require 3-inch clearance from insulation to prevent overheating. Always confirm the ceiling cavity depth accommodates the housing—most 4-inch retrofit kits require minimum 5.5 inches, while new construction housings need 6.5 inches. Use thermal management pads if specified by the manufacturer, especially in enclosed ceilings. Ensure all wiring complies with local electrical codes with secure connections in listed junction boxes. For optimal visual comfort in offices, select trims with baffles or reflectors to control glare, aiming for UGR < 19 in task areas. In hotels and malls, maintain consistent color temperature within 100K across batches and verify beam angles match the application—narrow beams (25°) for accent, wide floods (45°+) for ambient. Finally, conduct a photometric verification post-installation to confirm foot-candle levels meet IES standards for each space type.
