How to configure the right led power supply? 

Configuring the proper power supply for your COB LED strip is crucial to ensuring optimal performance and longevity of your lighting setup. The selection process involves calculating the required power and understanding the distinctions between waterproof and non-waterproof power supply options.

Calculating the Required Power

Before choosing a power supply, it's essential to calculate the necessary wattage. To do this, multiply the wattage per meter of the COB LED strip by the desired length of the strip. For instance, if you're using a 10W per meter COB LED strip and need to power a 5-meter length, the base calculation is 5 meters multiplied by 10W per meter, totaling 50 watts. However, to accommodate potential fluctuations and ensure reliable operation, it's advisable to add 20% to the calculated value. In this case, the final required power would be 60 watts. This additional margin safeguards against power spikes and other variables, making your COB strip's performance more stable.

Choosing the Right Power Supply

When selecting a power supply, it's vital to remember that you should never use a power supply with the same or lower power rating than the calculated required power. Opting for a power supply that exceeds the required wattage is permissible, as your COB strip will only draw the power it needs. For instance, if your COB strip's required power is 60 watts, a power supply rated at 60 watts or higher would be appropriate. In this way, you're ensuring that your power supply can adequately accommodate the demands of your lighting system.

Connection Considerations

When working with COB LED strips, it's important to consider the connection layout. Connecting a lengthy light strip can lead to excessive current and potential damage to the strip. For a COB LED strip with a 10-meter per watt specification, it's recommended to limit the longest strip length to 5 meters. If you need to cover a greater distance, connecting the strips in parallel before linking them to the power supply is advisable. This setup helps distribute the current evenly, reducing the risk of overloading the strips.

Waterproof vs. Non-Waterproof Power Supply

Power supplies are available in two main types: waterproof and non-waterproof. Waterproof power supplies come with a wire connection, making them suitable for setups exposed to moisture or outdoor conditions. On the other hand, non-waterproof power supplies feature terminal or DC terminal connections and are more suitable for indoor applications. The choice between these options depends on the specific requirements of your project.

In conclusion, configuring the right power supply for your COB LED strip involves accurate power calculation, choosing an appropriate power supply with a higher rating than the calculated power, and considering connection setups. Additionally, deciding between waterproof and non-waterproof power supplies depends on your project's environmental needs. By following these guidelines, you can ensure a safe, efficient, and reliable COB LED lighting system for your UK-based projects.
