Generally speaking, the higher the SMD number, the brighter the light. Also the higher the amp draw.
3528 strip are overly bright for interior lighting......which means 5050 strip
would be blinding.
Exterior lighting should be at least 5050s, if not 5630s.
If you plan on using a dimmer, keep this in mind: You need a switching dimmer, not your standard voltage dimmer. LEDs are on/off, with no in-between. That means lowering the voltage ain't gonna do squat. You need to reduce the amount of time the LEDs are lit -- basically, you need to adjust how rapidly they are switched on and off. A switching dimmer will decrease the amount of on/off cycles, increasing the amount of off time between on cycles -- but so fast that human eyes don't detect any flicker, only dimmer light.
