Technical Data
The light characteristic is "F WRG", i.e. a continuous light, coloured white, red or green depending on the bearing of the lighthouse. The light is emitted by a 2000 Watts Xenon lamp. On low visibility conditions a foghorn sounds a signal, the Morse code letters "AL" with an intervall of one minute.
On the tower a number of additional navigational and meteorological devices are installed next to the optics. Directional antennae and a radar serve as means of security in the Weser approach while an anemometer and an automated tide gauge collect data on wind conditions and water levels. The tower has a built-in emergency power system and provides accommodation for a maintenance crew.

Famous quotes containing the words technical and/or data:
“In effect, to follow, not to force the public inclination; to give a direction, a form, a technical dress, and a specific sanction, to the general sense of the community, is the true end of legislature.”
—Edmund Burke (1729–1797)
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
