It may be easier to think of colored LEDs (RGB) and white LEDs in terms of another industry: Automotive. RGB LEDs are like the internal combustion engine: Reliable, abundant, easy to use and manufacture, and fairly well developed in terms of the potential for new or breakthrough technologies. There are lots on manufacturers and each has their own set of patents and "tricks of the trade" to help give themselves some marketing leverage over the competition. White LEDs are like the alternative energy industry for transportation: Quite varied, still relatively "new", still needing to be market proven, more expensive, more challenging to manage. There are many manufacturers, each using a different technology or combination of technologies to achieve what they believe is the "the next big thing." Following this analogy, RGB LEDs are mature enough to compete on cost alone and the drop in costs is what fuels new applications for colored LEDs that had not been thought of previously. White LEDs, on the other hand are still developing technically and should not be shopped based on cost alone. The need for quality and longevity is what fuels the further research and development into white LEDs.
In the past, fluorescent lights were those long cumbersome glass tubes that needed special fixtures that had ballasts that sometimes burned out. Now, however, you can get fluorescent bulbs that fit right into the conventional light socket that is made for incandescent light bulbs. These fluorescent bulbs are not only compact enough to screw into a normal incandescent light socket, but the ballast is built into the base of the bulb, so there is no modification needed to do to the light socket. Furthermore, these lights are also different from the conventional fluorescent tubes despite the fact that they use the same kind of gaseous plasmas that conventional fluorescent lights use.
To make the room appear wider use ceiling lights directed towards the walls, taking care that the amount of light is uniform throughout the wall. This is even more effective in light-coloured walls. For a discrete illumination install lights hidden or half-hidden in the ceiling, trying not to reveal the source of the light. In hallways and stairs make sure this area is always well lit to prevent accidents and to create warm and welcoming. Paint the walls of the hall and stairs with a light color to reflect light better at it.
