Sunlight can create an optical phenomenon by the reflection of light through numerous tiny ice crystals suspended in the atmosphere or clouds; creating vertical shafts of light that extend upward (or downward). Light pillars; or columns of light beaming to the sky; are a spectacle that awes onlookers.
To artificially produce a light beam; a lamp and a parabolic reflector is used in many lighting devices; creating a directional projection of light which is beautiful and wondrous.
Incorporating wall lighting into your home adds many new avenues for featuring accents and furniture; extending lighting layers and depth; and developing the atmospheres of different rooms. The right layers in your exterior lighting plan will step things up toward being the most head-turning house on the block.
