In the modern architectural era, Rectangular LED Panel Lights have emerged as the gold standard for indoor illumination. From sprawling corporate offices in New York to high-tech manufacturing labs in Shenzhen, these fixtures provide more than just light—they provide an environment conducive to productivity, safety, and energy conservation. As the world pivots towards carbon neutrality, the demand for high-efficiency lighting has skyrocketed, positioning rectangular LED panels at the forefront of the global energy transition.
Globally, the commercial lighting market is undergoing a radical shift. Traditional fluorescent troffers are being phased out in favor of LED technology, which offers 50-70% energy savings and a significantly longer lifespan. Rectangular formats, particularly the 2x4ft and 1x4ft dimensions, are perfectly engineered to fit into standard T-bar ceiling grids, making them the most sought-after solution for retrofitting projects and new constructions alike.
The industry is no longer just about "turning on the lights." We are witnessing the rise of Human-Centric Lighting (HCL) and IoT-enabled panels. Today’s rectangular LED panels are often equipped with CCT (Correlated Color Temperature) tuning capabilities, allowing users to switch between warm white and daylight to match human circadian rhythms. Furthermore, smart sensors integrated into these panels enable motion detection and daylight harvesting, further optimizing power consumption in large industrial warehouses and smart offices.
Designed for large-scale commercial applications, our 2x4ft troffer light offers seamless integration into standard drop ceilings. With a back-lit design, it ensures uniform light distribution without the "yellowing" issues commonly associated with older edge-lit models.
Key Features: 4000 Lumens output, flicker-free driver, and UL/DLC certification for rebate eligibility in North American markets.
View Product DetailsWhen global enterprises and government contractors look for Rectangular LED Panel Light Manufacturers, their requirements go far beyond the unit price. Quality assurance, certification compliance (UL, CE, RoHS, SAA), and supply chain stability are the primary drivers of procurement decisions.
The versatility of rectangular LED panels makes them ideal for a wide variety of environments:
Designed for pharmaceutical labs, hospitals, and electronics manufacturing, this IP54-rated recessed light prevents dust ingress and is easy to sanitize. Its robust construction ensures long-term reliability in sensitive environments.
Technical Spec: 2x2ft dimensions, SMD technology, and precision-engineered seals for recessed mounting.
Explore SpecificationsChina continues to lead the world in LED lighting production for three primary reasons: unrivaled supply chain integration, rapid R&D cycles, and cost-efficiency at scale. As a specialized manufacturer, Hangzhou Velvet Light Co., Ltd. leverages these advantages to provide global clients with premium products at factory-direct pricing.
Being based in Hangzhou, we are at the heart of China’s technological innovation hub. This proximity allows us to source the highest quality chips (San'an, Osram, Bridgelux) and drivers (MeanWell, Lifud) while maintaining strict oversight of the manufacturing process. Unlike many trading companies, we operate our own production lines, ensuring that every rectangular panel leaving our facility meets international QC standards.

Its product portfolio includes LED panel lights for offices and commercial spaces, indoor lighting solutions for residential and retail environments, and robust parking garage and canopy lighting systems designed for safety and long-term operation.
The company operates a well-equipped production facility supported by a skilled team of engineers, quality control specialists, and experienced technicians. By integrating advanced LED technology with strict quality management processes, Hangzhou Velvet Light ensures consistent product performance and compliance with international standards.
Driven by innovation and sustainability, the company continues to invest in research and development, offering smart and energy-saving lighting solutions to global customers. Hangzhou Velvet Light Co., Ltd. is committed to delivering reliable products and building long-term partnerships worldwide.
The longevity of a rectangular LED panel is determined by three main components: the Frame, the Light Guide Plate (LGP), and the LED Driver. At Hangzhou Velvet Light, we prioritize these components to ensure our panels don't just look good on day one, but perform for a decade.
We use high-grade 6063 aviation aluminum for our frames. This provides superior heat dissipation, preventing the LEDs from overheating and ensuring the lumen maintenance stays above 90% after 50,000 hours.
Our panels feature Laser Dotting LGP technology. This ensures that the light is distributed evenly across the surface of the panel, eliminating dark spots and glare. We use PMMA material which is resistant to UV-aging, preventing yellowing.
The driver is the heart of the LED. We use constant current isolated drivers with high power factors (PF>0.95). They are protected against short circuits, over-voltage, and over-temperature.
