Suggestions on Finding the Appropriate Lighting Form to Display Your Framed Art
January 22, 2010
It [seems|appears} that after expending so much for a piece of art a painting, for examplemany people just stop considering what is best for it immediately afterwards, other than hanging it in the hall. Using apicture frame lighting or a led picture light becomes the end of the venture and nothing more remains but to admire the acquisition. It may not be incorrect, but such is certainly incomplete, in that with the wrong lighting system, the painting will not last as it must, nor show itself in the optimum, well, light. All art light are not equal.
Sun’s light?
Natural light such as sunshine is the optimum for vision, but not always for paintings and other [works|pieces} of art. For one, natural light is difficult to manage. It can be bright one hour and cloudy the next, depending on the vagaries of the skies. Second, its ultraviolet and infrared rays can wreak substantial damage to artworks, particularly watercolors, pastels and photographs, and fabrics. The ultraviolet rays diminish the colors in a short time, faster with unhindered sunlight, called bleaching which all of us are acquainted with. It is hence not appropriate for all art.
Incandescent light?
It has its upsides and negatives as well. Incandescent lights have strands that give off the light augment the warm tones yellow, orange, brown and red, but [renders|makes} the cooler colors rather dull. If the paintings or artworks are predominantly warm in color combinations, incandescent light could be appropriate. Another negative is its higher levels of heat radiation contrasted with alternative lighting systems because of the burning filament. The heat woulddamage the artwork.
What about fluorescent lighting?
Fluorescents produce light by making phosphors inside a glass tube glimmer with ultraviolet radiation from an inert gas and some evaporated mercury that are ionized with electricity. Since it is ultraviolet energy that makes the initial power, fluorescent lighting favors the cooler tones of the color spectrum: the blues and violets and greens, thus suppressing the other tones in comparison. Fluorescents can also emit high amounts of ultraviolet light which can damage paintings so like sunlight. Last, it does not release all colors of the light band, so that sets a different predicament for the display.
Is halogen lighting the most appropriate?
Halogen lighting is simply a development of incandescent lighting and uses halogen gas to make the tungsten emanation of the filament stick back to the filament, extending lamp usability. This process needs higher heat amounts so a halogen lamp is relatively hotter than other light sources. It can damage the art by drying the paint and making it splinter, so museums use motion sensors to switch lights off and on as necessary.
So what is best?
Until recently light emitting diodes (LED) give off light in primary colors. Chinese scientists some years ago combined blue and yellow in the correct blend to generate white, and white LEDs created a phenomenal explosion of uses, including lighting art pieces. It is white, low voltage, has long life, no heat and radiation to damage art, and is inexpensive. It being new, it is not as yet prevalent and as yet untested over time. Still, it appears to be the most suited system for everyone and all.
