fluorescent lamp

1. (Electrical Engineering) a type of lamp in which an electrical gas discharge is maintained in a tube with a thin layer of phosphor on its inside surface. The gas, which is often mercury vapour, emits ultraviolet radiation causing the phosphor to fluoresce
2. (Electrical Engineering) a type of lamp in which an electrical discharge is maintained in a tube containing a gas such as neon, mercury vapour, or sodium vapour at low pressure. Gas atoms in the discharge are struck by electrons and fluoresce

fluores′cent lamp′

a tubular electric discharge lamp in which light is produced by the fluorescence of phosphors coating the inside of the tube.

fluorescent lamp

fluo·res·cent lamp

A lamp that produces light by exciting the atoms of a mixture of argon gas and mercury vapor with electric current. Ultraviolet rays produced by the excited atoms strike a phosphor coating on the interior surface of the bulb, causing it to emit visible light. Fluorescent lamps are much more efficient than incandescent lamps because the excited atoms give off little of their energy as heat. Compare incandescent lamp.

Titled icon IV (the pure land), it copied an earlier construction (now lost), a Formica square topped horizontally by a single fluorescent tube. In 1962, when Flavin was first working on this piece, his twin brother, David John, died, and in my drawing the shrine-like object was turned into a memorial by a tomb-stone-type inscription that recorded his brother's birth and death date.
Moreover Flavin's lamp, a material thing (a fact highlighted by the presence, in many works, of the electric cord and supporting pan) is a luminous thing too: the fluorescent tube gives off a light that exceeds the thing itself, even if it does not entirely dissolve it.
The lamps can be used in either open or enclosed (IP65) fittings and are identified by a single green band around one end of the fluorescent tube.
This drop light is designed similarly to a standard fluorescent drop light, but offers improved performance and durability through the inclusion of a 15-watt LED tube lamp instead of the usual fragile fluorescent tube. This unit produces more light output than a standard 100-watt incandescent drop light, has no glass to shatter or break, has no filament and runs only slightly warm to the touch.
