Whether you display art in a gallery or hang it in your house, proper lighting should be an important consideration in order to maximimize the beauty of your art piece. There are three important aspects of lighting:

First, the angle and distance the lighting is from the art is very important. Generally an angle of 30 degrees is best to eliminate glare. Consequently the height of the ceilling where the lighting fixture will be hung will determine how far from the wall the light should be. See the diagram above.

Second, the color of the light (temperature in Kelvins) will greatly effect the appearance of the print. For a warm glow, choose a light with a 2700 Kelvin rating. 5000-5500 Kelvin is considered Daylight and will give the art a cooler appearance. In an experiment we conducted in our lobby, we found that some prints looked better with a 2700 K light (sunsets, oranges and reds) while others looked best with a cooler colored light of 5000K (blues, greens, purples). 

Third, the type of light is important. Many galleries still use halogen lighting to bring out the best in a print. The nice thing about Halogen lights is that their color range is much greater than LEDs. When dimmed they provide a beautiful warm glow, but when fully turned on, they provide a spectacular white illumination. The down side of halogens is that they consume 9 times as much energy as an LED and are hot.
