The unique design of the LED Tube Clock (also sometimes called the Digital Test Tube Clock) features six vibrant red diodes encapsulated in a clear plastic tubes. This 24-hour clock is reminiscent of the retro Nixie Clock but is far less expensive, and the LED's will last indefinitely unlike the pricey vacuum tubes of the Nixie Clocks. There are two tubes to display hours, two for minutes, and two for seconds. The clock measures 11”w x 3”d x 4”h and is finished with a simulated cherry wood grain. Power is supplied by the included 120V AC adapter.

Note: This is a 24-hour clock that operates on military time. 12am starts at 00:00:00, 12pm is 24:00:00.
