RGB COB LED strip means to make three colors of R, G and B on the same PCB board. The need for any color of the strip, or the need for gradient programs is realized through the RGB controller. There are currently two main ones: 630 and 840 lights per meter. 630 lights are 24V 10 wide PCB board, 18W per meter. The difference is that the 630 is relatively cheap, but the color of the 840 is better. The following video shows you the changing effect of RGB COB led Strip.

Yes, COB LED STRIP can be cut.

Yes, it’s can be dimmable with dimmer controller.

• The light-emitting chip adopts flip-chip technology, which has a cost advantage with the same number of lamp beads.
• Shorter heat dissipation path and lower thermal resistance, less light decay.
• No silver plating, no vulcanization risk
• Lighting angle can reach 180 degrees

• Poor color consistency control.

This is determined by the difference in the manufacturing process of COB LED STRIP and SMD light strips. The production process of SMD led strip is to first produce SMD lamp beads, and then split each lamp bead, and make the light bead after light separation to achieve color consistency on the same board. The COB LED STRIP is to flip the chip on the PCB board, and then drop the phosphor to achieve white light. Without the steps of light splitting, there is no way to achieve the consistency of the SMD led strip.

• Low power

Because the chips of the COB LED STRIP are too dense, it will affect the heat dissipation, so the power cannot be made too large, at most 14W per meter, and the SMD lamp beads of the SMD led strip have brackets, which can dissipate heat and can achieve 18W.

• Low luminous efficiency.

At present, the highest luminous efficiency of COB LED STRIP is: 120LM/W. SMD has a high-power lamp bead that can achieve 160-170LM/W. If the power requirement exceeds 120LM, you still need to choose a high-brightness SMD led strip.

• Flip chip, the defect rate is higher than that of SMD led stripwhen making waterproof led strip.
