Thought I'd toss in the way I light my living room and studio - halogen lamps! I have three torchères (floor lamps). One lamp provides all the light I need to read by and light my entire living room. The lamps provide indirect (reflected) lighting from a reflective ceiling - in my case off white.
Yes, the halogen is hazardous if you are careless and let something flammable contact the bulb, but otherwise they are low energy users and produce an amazing amount of light for such tiny bulbs. And my bulbs have lasted several years before needing replacing.
For my studio space I've tried all sorts of lighting combinations trying to find a close match to sunlight and the halogen is as close as I've managed to get without spending much more for special color-corrected bulbs. My lamps also have dimmer switches, which is nice for subtler lighting. They were also inexpensive when I bought them at about $20 apiece.
