Smooth White Series COB LED Arrays Luminus Devices Generation Smooth White COB LED Arrays are high-power LEDs with a high lumen output and efficacy that reduces power consumption. The LEDs provide a correlated colour temperature (CCT) range of 2700K, 3000K, 3500K, and 4000K. The White LEDs feature has a large selection of light-emitting surfaces (LES), operating power ranges, and colour qualities. These COB LED Arrays also feature pure white colour rendering with excellent colour saturation and optimum appearance. These LEDs have long-term colour stability, superior thermal conductivity, and optical emission uniformity. The smooth white COB LED arrays are RoHS and REACH compliant, making these LEDs environmentally friendly. The extensive applications of these LEDs include spotlights/track lights, downlights, shop lighting, hospitality lighting, architectural/specialist/parking area lighting, and street/tunnel lighting.
