I have RGB+W LED strips that light my home office. http://imgur.com/a/JgWV8 http://imgur.com/a/JgWV8 The LEDs are 5050's (not individually addressable), and it alternates between white and RGB LEDs, controlled via analog/PWM (there are +5V, R, G, B and W connections). I bought this from ebay, and it came with a remote and controller (and a crappy wifi controller that I've never gotten to stay connected and working for more than 2 minutes). The remote is kind of crappy, but it does allow independent control of white brightness, RGB hue, and RGB brightness. My office is a 10x10 room with a vaulted ceiling, and I have two boxes each with two 1m strips (4m total) mounted on top of cabinets on opposite sides of the room, shining up and mostly reflecting off the ceiling. I'm very happy with this. That said, I primarily use the white (which is a "warm white") though often mix in some subtle color (eg: 50% brightness of the white). At night I'll often have more of a 1:1 mix or even the color slightly stronger, just because. When turned up full, it's significantly brighter than the 50W halogen floor lamp I used to have in here. The key thing that makes this usable for me is the white LEDs. Just to see if the RGBW vs RGB strip was worthwhile, I did actually try turning the RGBs on full when I was building it (the controller I have doesn't let you do this) and it's just not quite the same. Even though I have the strips projecting onto the ceiling (so it's indirect, soft light), the color is just.. off. If you're considering RGB LED strips as general purpose lighting, I'd highly recommend to either go with RGBW or mount a white LED strip alongside the RGB one.
