Type of LED
3528 - Thin light - Ideal for most home situations for work or ambient lighting where observers are nearby. Like plateaus, under the offices, on the stairs and around the windows
5050 - Bright light - Ideal for commercial or home use, where the observer may be farther away - Like high ceilings, used as a wall washer, outside lighting, ambient lighting for larger areas. 5050 can also be used to change color RGB or RGBW LED tape.
2835 - Much smaller and thinner than 5050, 5730 and 3528, you can see 2835 SMDs as a more efficient replacement for the 5050 producing 20% more light on the same power consumption.
5630 - Basically a stretched LED 5050 with a much wider viewing angle. The wider angle facilitates the emission of brighter performance with the same power
2216 - New innovation, much smaller and thinner than 3528 SMD LED, high-density led available as 300leds/m or 420leds/m, to achieve the best even light without led dot.
