   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.

6. Bi-pin lamp base - Wikipedia

   en.wikipedia.org/wiki/Bi-pin_lamp_base

   The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...

   It lasts from 1 to 4 weeks, and is the period of greatest vulnerability in the life cycle of the plant, requiring moderate humidity levels, medium to high light intensity, and adequate but not excessive soil moisture. Most indoor growers use compact fluorescent or T5 fluorescent lights during this stage as they produce little heat.
