Generally, SMD LEDs are rectangular, so its name is based on the size L x W, so the 3528 & 5050 with different dimension, another difference is usually the 3528 type with 1 LED chip inside, but 5050 can have 3 chips inside.
For the IP65 means the equipment can be used in outdoor permanently, and protect from the rainning and dust, and IP68 means it can be use underwater, and can bear the water pressure, Of course Higher protect than IP65.
