A modular cove lighting system is formed of tubular fluorescent light fixtures connected together in parallel. The modular system is capable of providing uniform illumination along its length. The modular system advantageously may include straight lamps, curved lamps (including lamps forming 90° angles), and/or hinged lamp fixtures. The system may be constructed with lamps that are illuminated completely from end to end, which can then be lined up end-to-end to create the illusion of one continuous lamp. Through special matching of ballasts and appropriate lamps, the lamps will dim evenly with each other, regardless of the lengths and shapes of the lamps. Each lamp and ballast is completely contained in a casing to form a cove lighting module. Multicolor systems formed of one or more light fixtures are also disclosed. A recessed light fixture is also disclosed.
A lamp base for use with a lamp having a first tube illuminated along its entire length, a second tube connected to the first tube and a third tube connected to the second tube, the first, second and third tubes being in fluid communication, the third tube being disposed in parallel spaced-apart relation with the first tube and enclosing an electrode, the lamp base comprising a first portion for supporting the first tube and a second portion for supporting the third tube, such that said electrode is located between said second tube and said lamp base, the first and second portions cooperating to retain the first and third tubes in spaced-apart relation.
