I'm building a lighting system that will use a 3m length of 5630 LED strips at 60 LEDs per meter (generic Chinese eBay LED strips). In my personal research, 3m will have a 72W/6A draw. I'll be using a potentiometer or PWM to dim the lights as needed (I'll figure that out later). If I get a 12v 6A transformer, will that be adequate or should I get something rated higher as a precaution? Next question: I'm lighting my studio apartment. My current light source is a single 3-way light bulb with a max brightness of 1750 lumens. However I'm seeing that a single 5630 is 45 lumens. That means that this strip will get up to 8100 lumens, which seems way too bright. Are those numbers correct? Would I be better off using 5050's (or even 2x 3528's)? Thanks in advance.
