The attic is often where sentimental items are stored, and can also serve as an additional room. Whether you're using the attic as a bedroom, home office or treasure chest, there are solutions to every lighting need.
If the attic is compact, a small light fixture on the ceiling with a slightly bright bulb is sufficient; a lamp in the corner of the attic may provide enough lighting as well. For larger attics, fluorescent or bright light bulbs may be best. Recessed lighting also works well for spacious attics.
Attic lighting should also coordinate with what you use the space for. If the attic is also your home office, a main light is necessary, but a light installed on or near the desk is the most efficient use. And you don't have to rework the electrical system to do it. For attics that serve as storage spaces, corner lamps can compliment the ceiling light fixture to make locating your most cherished items easier.
Determine how much light the attic receives from any windows to determine how much additional light you need to install in the space. An attic fan that is powered by the sun's energy is also an alternative to lighting, especially if you live in particularly sunny climate. The fans will help conserve energy and even prevent mould and mildew growth in the attic.
