A troffer is a rectangular light fixture that fits into a modular dropped ceiling grid (i.e. 2' by 2' or 2' by 4'). Troffer fixtures have typically been designed to accommodate standard fluorescent lamps (T12, T8, or T5), but are now often designed with integral LED sources. Troffers are typically recessed sitting above the ceiling grid, but ...
Outdoor light fixtures can also include forms similar to indoor lighting, such as pendants, flush or close-to-ceiling light fixtures, wall-mounted lanterns and dome lights. High-mast, usually pole – or stanchion-mounted – for landscape, roadways, and parking lots.
Sloped-ceiling housings are available for both insulated and non-insulated ceilings that are vaulted. The main feature of the housing is designed to ensure that no flammable materials come into contact with the hot lighting fixture. Badly-housed downlights can be a fire hazard, though all newer ones contain a self-resetting thermal switch for ...
A pendant light, sometimes called a drop or suspender, is a lone light fixture that hangs from the ceiling usually suspended by a cord, chain, or metal rod. [1] Pendant lights are often used in multiples, hung in a straight line over kitchen countertops and dinette sets or sometimes in bathrooms.
Traditionally, cove lighting was installed by using T5 fluorescent tubes. T5 luminaires are an energy-efficient alternative to larger luminaires (such as T8 lamps) because they save on materials. [2] Lighting specialists recommend installing cove lighting at least 18 inches (46 cm) from the ceiling and 6 feet 8 inches (2.03 m) from the floor.

Two effects are responsible for this: the waveform of the voltage emitted by a standard phase-control dimmer interacts badly with many ballasts, and it becomes difficult to sustain an arc in the fluorescent tube at low power levels.
