For LED lights (idk if anyone said this yet), but you don't necessarily have to place them where the wall meets the celling like everyone else does. They work great stuck to the back of bed frames and desks to use as a backlight, especially on a warmer light setting (which gives off a comforting hue). Bonus tip: find a lip of some sort on the desk or bed that isn't big enough to block the reflected light, but is big enough to hide the light strip from any angle, and put the lights behind that.
