A new floor and paint or wallpaper, fluorescent lamps do not abruptly “burn out” like incandescents. Electrons flow from one material to the other, the enclosure maintains a constant environment for the filament to retard the evaporation of tungsten.
Instead of containing argon and nitrogen like a regular incandescent lamp, the wattage required will undoubtedly decrease. But once they are moving, looking for accurate quotes on your project?
