I purchased them from lighthouse leds. They are located in Washington state. They are
plcc-2 SMD clear white ultra bright 1210/3528 leds. At one time I was pretty familiar with the terminology but I believe 1210 and 3528 are different names for the same thing. Plcc is a plastic leadless chip carrier and 1210/3528 refers to the dimensions.
I hope to have a post with step by step instructions up soon. It is fairly straight forward but any mistakes would be hard to correct obviously
