SMD Ceramic LED, available in alumina and aluminum nitride materials, has stronger thermal conductivity than conventional SMDS, so in smaller sizes, you can make more power, conventional sizes are 3535,5050, and special 3636,3939,7070,5060,6065 and so on. The power of a single 0.5W,1W,3W, up to 40W, at most can be divided into 5 channels control, if you have special requirements, you can consult and customize
