24V 5-in-1 Dimmable Universal LED Transformer | 40W - 288W

Step 1: Determine Total Wattage

Calculate the total wattage of the LED strip lights you plan to use. This is done by multiplying the strip's wattage per foot (or meter) by the total length you'll need.

For example, if your strip uses 5 watts per foot and you need 20 feet, the calculation is:

Total Wattage = 5 watts per foot × 20 feet = 100 watts

Step 2: Add a Safety Margin

To ensure reliability and prevent overload, it's wise to add a safety margin of 20% to your total wattage. This means you will need a transformer that can handle:

$\text{Required Transformer Capacity }=\text{Total Wattage }\times 1.2,\; so100\text{watts }\times 1.2=120\text{watts}$

Therefore, in this example, you should select a transformer with at least 120 watts capacity.

*Example: a 16.4ft strip is 50 watts x 1.2 = 60 watt driver is needed
