Is there any advantages of the product? 
These energy-efficient LEDs deliver superior brightness with low power consumption, feature universal 2.54mm spacing for broad compatibility, and come in bulk 50pcs value pack.The 7-core structure enhances the bendability of the wire, avoids frequent bending and breakage, extends its service life, and the copper cores improve current transmission efficiency.

How to use it? 
Insert the longer anode lead (+) to positive voltage (12V) and shorter cathode lead (-) to ground through current-limiting resistor.

What should I notice? 
Critical: Always observe correct polarity and use current-limiting resistor; not suitable for wet environments; reverse connection may damage components.
