   en.wikipedia.org/wiki/LED_tube

   LED tubes. LED tube is a type of LED lamp used in fluorescent tube luminaires with G5 and G13 bases to replace traditional fluorescent tubes. [1] As compared to fluorescent tubes, the most important advantages of LED tubes are energy efficiency and long service life. LED tubes are sometimes also referred to as ‘LED fluorescent tubes’.

5. Solid-state lighting - Wikipedia

   en.wikipedia.org/wiki/Solid-state_lighting

   Most common "white LEDs” convert blue light from a solid-state device to an (approximate) white light spectrum using photoluminescence, the same principle used in conventional fluorescent tubes. The typically small mass of a solid-state electronic lighting device provides for greater resistance to shock and vibration compared to brittle glass ...

   T12 fluorescent tubes. The first two are rapid start, (for "tombstone" and socket holders respectively) while the third is an instant-start lamp. The instant-start has a characteristic, rounded, single pin, for plugging into the spring-loaded socket holders. Instant start fluorescent tubes were invented in 1944. Instant start simply uses a high ...
