SlimLine COB LED Strip Collection – Revolutionizing Ambient Lighting
Ultra-Narrow LED Strip Lights FAQ
The reduced width of LED light strips does not significantly diminish light output. The slim illumination is primarily designed for ambient lighting, perfectly meeting the needs of both residential and architectural lighting applications.
This depends on your specific application. Typically, SMD LED mini strip lights require extremely high LED density and deep groove depth to achieve a completely spot-free linear effect. COB LED strips, due to their inherent characteristics, offer greater versatility.
Yes. Due to the extremely narrow PCB, no connectors are available below 5 millimeters in width. Manual soldering is recommended instead.
In fact, aside from low-voltage 5V, 12V and 24V thin light strips, consistency remains good across the length of each roll. Some require power supply at only one end, while others may need power supply at both ends.
