Led Chip

Simply put, these LED chips are called SMD 5050 because the dimensions of the chips are 5.0mm x 5.0mm. They have 3 LED diodes in one housing (sometimes called tri-chips), and are a lot brighter than individual 3528 LED chips.

5050 SMDs used in RGB LED strip lightingThe 5050 SMD is actually a 'tri' chip, meaning it has three smaller chips in every SMD. So each white LED actually has three white chips inside. 5050s can also be used for colour-changing LED tape, with red, green and blue chips inside
