Modern lighting can transform a gray dismal room into one with energy, and can even improve the acoustics. While you are at it, wash the globe covers. Lighting needs change according to the time of day and the weather. Rheostats will give you control over the intensity. Rather than having all lights on one switch, break them into sections so you can adjust lighting by area.
Dramatic lighting accentuates focal points.
Draw attention to the primary symbols of our faith by focusing intense light on the alter table, the place of the word, and the font. Lessen distractions by decreasing the amount of light on other objects, such as the east wall and less important symbols. Pay as much attention to the order and cleanliness of the back of the church as the front. If you do not regularly polish the brass, consider having it burnished and lacquered. Extraneous furnishing becomes clutter.
