48″ LED Circular Panel Pendant Light

The 48″ Circular Panel Pendant Light (Model: FP603HLM10048BVKD4W) is a large-scale, monolithic architectural luminaire engineered for commercial office spaces, corporate conference rooms, car dealership showrooms, hospitality lobbies, and high-ceiling reception areas.

Featuring a heavy-duty extrusion aluminum round frame with a 47.24″ (1200mm) overall diameter and a slim 2.17″ housing profile, this commercial disc light provides high-performance, 100% downward-directed ambient illumination. Unlike traditional hollow ring or halo fixtures, its full-surface optical layout utilizes a performance-engineered diffuser assembly to deliver a clean, uniform, and glare-controlled light distribution over large footprints.

Equipped with field-adjustable flexibility, this 4ft diameter commercial pendant allows electrical contractors to select output wattages (60W/80W/100W) and adjust color temperatures (3CCT tunable) directly on-site using integrated dip switches. This multi-configuration capability significantly reduces stock keeping complexity (SKU reduction) for wholesale distributors and importing supply chains.

Commercial B2B FAQ: For Contractors, Distributors & Importers

Q1: How does the on-site field-adjustable wattage and CCT feature benefit distributors and stocking importers?

A: Our 48″ LED circular panel pendant light features integrated dip switches that allow on-site selection between three wattages (60W/80W/100W) and three color temperatures. For importers and wholesale distributors, this 3-Wattage & 3-CCT selectable design means one single SKU can fulfill up to 9 different project specifications. This dramatically reduces your warehouse inventory carrying costs, minimizes dead stock, and speeds up project fulfillment times for electrical contractors.

Q2: What type of dimming protocol does this 4ft diameter commercial fixture support? Is it compatible with standard building automation systems?

A: The luminaire comes standard with a high-performance Class II/P driver supporting 0-10V continuous dimming with a power factor greater than 0.98. This ensures seamless compatibility with commercial building automation systems and major North American commercial dimmers (such as Lutron, Leviton, and Delta Controls). For specialized retrofits, Triac dimming options are also available upon factory request.

Q3: Is this large round pendant light pre-certified for North American electrical inspections?

A: Yes. The entire FP603H series is UL and cULus listed for damp locations, ensuring it fully complies with the National Electrical Code (NEC) in the United States and the Canadian Electrical Code (CEC). Factory production strictly follows ISO quality management standards, and the fixtures are verified under LM-79 and LM-80 performance metrics to clear any job-site inspection hurdles seamlessly.

Q4: How do you ensure the 47.24″ large-scale aluminum frame does not sag or warp over time?

A: Unlike cheap stamped metal or plastic alternatives, our round frame utilizes heavy-duty extrusion aluminum. This advanced structural design provides superior rigidity and hardness to prevent sagging across the 4ft diameter span, while simultaneously serving as an oversized passive heat sink. Coupled with a 5-stage phosphate bonding process and baked enamel finish, the housing resists yellowing, chipping, and thermal degradation, guaranteeing a 50,000+ hour operating life.

Q5: Can this fixture be surface-mounted if the plenum space has zero clearance for aircraft cables?

A: Yes. While the standard configuration comes complete with an 8.66″ canopy and 6-foot (72″) adjustable powered aircraft cables for suspended installation, we also manufacture a dedicated surface-mount hardware kit. Contractors can order the surface-mount kit separately to flush-mount the disc light directly to hard ceilings or low-clearance structural grids.

Q6: Does the luminaire include an integrated driver disconnect to meet US and Canadian safety codes?

A: Yes. To ensure contractor safety during maintenance and to satisfy strict localized electrical codes across North America, a factory-installed driver disconnect is provided where required by regional regulations.

Q7: What are the packaging options for bulk import shipments to prevent transit damage?

A: Given the large 1200mm (47.24″) physical footprint of the 48″ model, we utilize export-grade, reinforced honeycomb padding and high-density foam edge protectors for bulk container shipments from our manufacturing centers. We offer flexible OEM/ODM bundling options, including blank-box packaging for private labeling or custom contractor-pack palletization to streamline delivery straight to US/Canadian job sites. Emergency battery backup (8W 90-Min EM kit) and occupancy sensors can also be pre-installed at the factory level to save field-labor costs.
