| Edge-Lit LED Panel | LEDs are mounted around the edge of a slim light guide that distributes light across the front surface. | Approx. 90–120 lm/W | Very good when the light guide and diffuser are well designed. | Typically 50,000–60,000 hours | Offices, classrooms, retail spaces, corridors, and low-ceiling installations. | Slim profile, low glare potential, lightweight construction, and attractive appearance. | The light guide can yellow or lose uniformity over time; thermal management is concentrated around the edges. |
| Backlit LED Panel | LED modules are distributed across the rear of the panel and shine directly through a diffuser. | Approx. 100–140 lm/W | Excellent with adequate LED spacing and optical diffusion. | Typically 50,000–100,000 hours | Commercial offices, supermarkets, hospitals, warehouses, and general-purpose ceiling lighting. | Strong thermal performance, reliable uniformity, and less dependence on a light guide. | Usually thicker than edge-lit designs and may require more material and installation depth. |
| SMD LED Panel | Surface-mount LED packages are soldered directly to a printed circuit board or LED module. | Approx. 90–160 lm/W | Good to excellent, depending on diffuser, spacing, and optical design. | Typically 50,000–100,000 hours | General indoor lighting, task lighting, commercial fixtures, and retrofit products. | Flexible design options, high availability, efficient production, and a broad range of color temperatures. | Performance varies widely with LED package quality, driver design, and heat dissipation. |
| COB LED Panel | Multiple LED chips are mounted closely together on a substrate and covered with a common phosphor layer. | Approx. 100–160 lm/W | High visual uniformity with a continuous-looking emitting surface. | Typically 50,000–100,000 hours | High-output luminaires, architectural lighting, retail displays, and applications requiring compact light sources. | High LED density, compact footprint, smooth appearance, and good optical control. | Higher heat density can increase thermal-management demands; repairs may be less modular. |
| Tunable White LED Panel | Separate warm-white and cool-white LED channels allow the color temperature to be adjusted. | Approx. 80–130 lm/W | Very good when both LED channels are evenly mixed. | Typically 50,000–75,000 hours | Healthcare, education, offices, hospitality, studios, and human-centric lighting schemes. | Adjustable white appearance, scheduling capability, and improved flexibility for different activities. | Requires compatible controls and wiring; maximum output may change at different color-temperature settings. |
| RGB or RGBW LED Panel | Red, green, and blue LEDs create colored light; RGBW adds a dedicated white LED channel. | Approx. 50–110 lm/W for white output, depending on configuration | Good to excellent with proper pixel mixing and diffusion. | Typically 30,000–70,000 hours | Entertainment, exhibitions, signage, decorative interiors, events, and accent lighting. | Wide color range, dynamic effects, programmable scenes, and strong visual impact. | More complex controls, lower efficiency in some colors, and generally higher system cost. |
| High-CRI LED Panel | LEDs are selected and phosphor-engineered to provide more accurate color rendering, commonly CRI 90 or higher. | Approx. 70–120 lm/W | Good to excellent, depending on the panel's optical construction. | Typically 40,000–75,000 hours | Art and design spaces, retail, photography, healthcare, hospitality, and premium offices. | More natural-looking colors and improved visual assessment of materials, skin tones, and products. | Often produces fewer lumens per watt and may cost more than standard-CRI panels. |
