3528 SMD LED is nearly the longest history SMD LED components, ‘3528’ itself means this SMD LED component is about 3.5mm(L)X2.8mm(W).
Normally, the most used 3528 SMD LED have 1 chips inside, it can be Red LED chips, Blue chips, Green chips, Yellow(Amber) chips to output Red color, Blue color, Green color, Yellow(Amber) color, and using a blue chip and the phosphor together to fabricate the white LED to output like 3000K, 4000K, 6000K different white colors.
3528 SMD LED components are widely used for many products. In Coolight LED lighting, we use them most to make different LED strip products, mainly for flexible LED strips.
In 2014, we signed a long-term strategy contract with the quality LED component manufacturer-Refond company.
