To Start, Lets Talk About What These 3 Number Codes Mean When Applied To LED Chips Types.

3528 LED 5050 LED and 5630 (5730) LED are the 3 most commonly used surface mount diodes for flex strip lighting. They are traditionally used in mono-lights or RGB flex LED strip lighting.(aff.) As LED technology advances, these 3 types of LED chip are now used for home and commercial lighting to replace compact fluorescent and other incandescent lighting.

 
Once you see the 3 types of diodes, you can easily tell that the 3528 LED is smaller in size than the 5050 LED. But what most people do not know is this , a 5050 LED actually contains 3 sets of 3528 LED chips inside. So a 5050 LED is actual a combination of 3x 3528 chips in 1.

The 5630 (5730) LED is basically a stretched 5050 LED with a much wider viewing angle. Making the 5630 (5730) LED the brightest of all 3 with the lowest power consumption per watts. The wider angle makes it easy to emit a brighter output with the same wattage.

A 3528 LED will illuminate brightness equivalent to approximately 6 Lumen

A 5050 LED diode will illuminate brightness equivalent to approximately 18 Lumen

A 5630 (5730) LED diode will illuminate brightness equivalent to approximately 50 Lumen

The same goes for each chip's power consumption, a 3528 LED will consume approximately 0.06 Watt, while a 5050 LED will consume approximately 0.18 Watt of power and a 5630 (5730) consumes about 0.5 Watt.
