light bulbs.

As technology progresses light emitting devices are becoming more efficient and increasingly compact. Because of the size and static shape of traditional bulbs most lighting design has been primarily concerned with disguising or accesorising the light bulb in such a way as to make it more pleasing to have around. This involved improving the look of the bulb and improving the quality of light it casts. As bulb technology has allowed light to come from smaller and smaller sources, the design of light fixtures is involved more in the quality of light. This is especially true with new advances in LED technology and fiber optic technology. Both of these are allowing structural materials to emit light which totally circumvents the traditional concerns of lighting design. It seems that the coarse we are currently on will soon lead to the possibility of having uniform light on any intensity and any wavelength evenly distributed through any environment. This kind of control over our environment has some pretty crazy implications. What kind of light is "best", questions like these are difficult to answer when technology no longer limits us to specific vehicles for output. I would like the paint on my ceiling to replicate the dappled light of a shady willow tree on a breezy sunny day.
