Belgian designer Bart Lens has designed a ceiling lamp for eden design which, at four metres wide, they claim is the largest lamp in production.
The °XXXLamp measures 4m x 160m and is inspired by a Chinese lantern.
Here's some info from eden design:

Perhaps symptomatic of an architect’s mindset, the lamps and objects are becoming increasingly ‘space defining’. The XXL-amp is essentially a flattened dome, inspired by the shape of a Chinese lantern. The twelve-segment construction makes the connection with the lantern, but a pumpkin is perhaps the first association that comes to mind, while the suspension system recalls an upside-down hot-air balloon.
If the ceiling is high, but not overly high, then the lamp can be hung at about 1.30m. As befits any impressive space, you’ll want to enter with a slight bow. Once seated at the dining or conference table, you’ll still retain a sense of the surroundings beyond the boundary. Hanging a half or a quarter XXL in a mirrored room creates an impression of spacious rooms full of giant lanterns.
