                                                                                                                                        COB (Chip on Board) LED strips consist of many tiny LED chips mounted directly onto a flexible circuit board (FPCB). A phosphor layer covers the chips, diffusing the light and creating a uniform glow. This high chip density allows for a brighter and more even light output compared to traditional SMD (Surface Mounted Device) strips with individual LEDs.

                                                                                                                                        All LED strips generate some heat, but COB strips are generally designed with good heat dissipation. The larger surface area of the COB design allows for better heat management compared to some SMD strips. However, for long runs or high-wattage strips, a heat sink might be recommended for optimal performance and lifespan.

                                                                                                                                        COB LED strips boast a long lifespan, typically rated for up to 50,000 hours. This translates to years of use, assuming several hours of operation daily. However, the actual lifespan can vary depending on factors like quality, operating temperature, and usage frequency.

                                                                                                                                        COB strips can achieve high brightness, but not necessarily the highest compared to some high-powered SMD strips. However, COB strips excel in delivering a more uniform and smooth light output, making them appear brighter due to the lack of visible LED dots.

                                                                                                                                        Yes, COB LED strips can be cut at designated points, usually marked with scissors icons. Make sure to use sharp tools and cut only at designated markings to avoid damaging the circuit and ensure proper functionality.

                                                                                                                                        COB strips are generally considered efficient, with good heat dissipation contributing to longer lifespans. However, efficiency can also depend on factors like the specific LED technology used.

                                                                                                                                        Not all COB strips are waterproof. Look for strips with an IP rating suitable for outdoor use. Higher IP ratings indicate better resistance to dust and moisture.

                                                                                                                                        COB strips require a compatible power supply that meets the strip’s voltage and wattage requirements. Always calculate the total wattage of your strip setup before choosing a power supply and ensure proper polarity when connecting.

                                                                                                                                        Yes, many COB strips are compatible with dimmers. Choose a dimmer that matches the strip’s voltage and power requirements. Dimming functionality might also require a compatible controller depending on the setup.

                                                                                                                                        While COB strips are designed for long lifespans, continuous operation is not always recommended. Following manufacturer recommendations for on/off cycles and duty cycles (percentage of time on) will help maximize lifespan.

                                                                                                                                        COB strips generally offer good flexibility, allowing for bends around corners. For very tight corners, some manufacturers offer cornering solutions or specialized COB strips designed for tighter bends.

                                                                                                                                        Repairing individual LEDs on a COB strip is usually not feasible. However, if a section stops working, you might be able to isolate the issue and bypass the faulty section if the strip is designed for such a configuration. Otherwise, replacement might be necessary.

                                                                                                                                        For shorter strips and lower wattages, a heat sink might not be necessary. However, for longer runs, high-wattage strips, or situations with limited air circulation, using a heat sink is recommended to ensure proper heat dissipation and maximize lifespan.

                                                                                                                                        There are various methods for connecting COB strips, depending on the strip type. Soldering and solderless connectors are common options. Ensure the connectors match the strip’s width and pin configuration for a secure connection.

                                                                                                                                        Yes, some COB LED strips are compatible with smart controllers that can be integrated with smartphone apps or smart home systems, allowing for control features like dimming, color changing, and scheduling.
