Purchase gallery flood lights that are three times the brightness of your room lighting. Also, try to purchase a combination of halogen and incandescent lights for the most effective results.
Place the flood lights approximately three feet above the artwork to begin, but do not attach them to your wall or ceiling yet.
Adjust the height of each flood light so that the light is evenly cast over the entire work. You also want to ensure that there is not an excessive amount of heat being directed at the artwork. Place your hand near the top of the painting to test; there should be little or no difference between room temperature and the temperature of your hand.
Attach your swivel flood light brackets to the wall at the height you decided in Step 4 using the screws provided and your screwdriver. Space the brackets evenly over top of the artwork.
Set your flood lights into the brackets and attach them using the brace provided. Angle the flood lights at approximately 30 degrees to the wall.
