Emitting visible light as a result of the excitation of phosphors by ultraviolet photons produced by the passage of an electrical current through an inert gas infused with mercury.
The quality of fluorescent lighting technology has improved dramatically in recent years.
The shed, a steel-framed structure with a single-span roof devoid of intermediate support, is exceptionally well-lit by continuous glazing on the roof and along much of the sides, while there is fluorescent roof lighting for night work.1960 July 23, “New Eastern Region diesel depot at Finsbury Park”, in Trains Illustrated, pages 422–423:

Rather than burning out as incandescent bulbs do, L.E.D.’s light output dims over tens of thousands of hours. L.E.D.’s are also more resistant to vibration than incandescents or screw-in fluorescent bulbs, and do not flicker or hum.2007 March 1, Matthew L.

Then they backed the membrane with a gel matrix containing a perfluorocarbon (PFC) propellant and fluorescent "nanobullets" about a micron wide, and hit it with ultrasound.2016 January 14, Jessica Hall, “Nanoengineers build 'microcannons' that fire light-up bullets filled with drugs”, in ExtremeTech:
Compact fluorescents are typically rated at 7,500 to 10,000 hours, and incandescents at about 1,500 hours.2007 March 1, Matthew L. Wald, “Room to Improve”, in The New York Times, archived from the original on 03 Jun 2017:
