It [seems|appears} that after expending so much for a piece of art a painting, for instancemany people just stop thinking of what is appropriate for it right afterwards, other than hanging it in the hall. Using apicture frame lighting or a led picture light becomes the be all of the venture and no more remains but to gaze the acquisition. It may not be faulty, but such is definitely lacking, in that with the mistaken lighting method, the painting will not last as it should, nor show itself in the best, well, light. All art light are hardly equal.

Natural light?

Natural light such as sunshine is the best for vision, but not all the time for watercolors and other [works|pieces} of art. First, natural light is difficult to control. It can be bright one moment and dark the next, according to the vagaries of the heavens. Second, its ultraviolet and infrared rays can wreak considerable damage to artworks, especially watercolors, pastels and photos, and fabrics. The ultraviolet rays diminish the hues in a short time, quicker with unhindered sunlight, called bleaching which all of us are acquainted with. It is thus not good for all art.

Incandescent light?

It has its positives and downsides as well. Incandescent lighting have filaments that emit the light augment the hot tones yellow, orange, brown and red, but [renders|makes} the cooler hues rather flat. If the paintings or artworks are predominantly warm in color tones, incandescent light could be appropriate. Another downside is its greater levels of heat radiation compared with alternative lighting methods because of the glowing filament. The heat willdamage the artwork.

What about phosphor lighting?

Fluorescents produce light by making phosphors inside a glass tube glimmer with ultraviolet energy from an inert gas plus some vaporized mercury that are ionized with electric current. Since it is ultraviolet energy that makes the initial power, fluorescent lighting favors the cooler tones of the color band: the blues and violets and greens, thus suppressing the other tones in contrast. Fluorescents can also radiate high amounts of ultraviolet light which can damage paintings much like sunlight. Finally, it does not emit all colors of the spectrum, so that poses a whole new problem for the display.

Is halogen lighting the best?

Halogen lighting is simply a development of incandescent lighting that uses halogen gas to make the tungsten vapor of the filament stick back to the filament, prolonging lamp usability. This process requires higher heat amounts so a halogen lamp is relatively hotter than other light producers. It can damage the art by dehydrating the paint and making it splinter, so museums use motion sensors to turn lights off and on as needed.

So what is best?

Until recently light emitting diodes (LED) emit light in primary tones. Chinese scientists a few years ago combined blue and yellow in the correct amounts to generate white, and white LEDs created a sensational explosion of uses, including illuminating art pieces. It is white, low voltage, has long life, no heat and radiation to damage art, and is low cost. It being new, it is not as yet prevalent and still unproven over time. Nevertheless, it appears to be the most suited system for each one and all.
