NOT ALL LED IS THE SAME
Our American flexible printed circuit board is a standard 3oz thickness, ensuring better heat performance and a reduction in voltage drop maintaining LED brightness versus the Chinese equivalent with a 1-2oz PCB which can result in early failure.
Solder paste on our American ribbon has a higher silver content improving performance in electric conduction. The higher silver content also improves ribbon flexibility, the cheaper alternative tends to break easily during the installation process.
One bin selection by our American manufacturer ensures tight control of +/-100K compared to inferior ribbon which bins at anything up to +/-1000K. It should be noted that the naked eye can recognise a colour shift from 300K and above.
