GE 46688 - F21W/T5/850/ECO

This is not an LED lamp, but a conventional 21-watt, 34-inch (nominally called 36 inch or 3 foot sometimes) T5 fluorescent tube with two male G5 miniature bi-pin sockets on either end.

While it delivers reliable performance, please note that this tube contains mercury, so proper handling and disposal are required when it burns out.

Additionally, it is no longer considered an energy-efficient choice. The colour is 5000 Kelvin, and requires a ballast to operate, which can also fail. This tube provides between 1700 and 2100 lumens over its lifespan and has a minimum rated life of 20,000 hours.
