German to English translations [PRO] Tech/Engineering - Construction / Civil Engineering / Electric lighting - building illumination
German term or phrase:Strahler
Lighting for building/monument illuminations. Metal/halogen vapour lamps, sodium vapour lamps, and fluorescent tubes are used.
"Beim Objekt (name of monument) konnte die Energiebilanz auf 80% mit dem 7-fachen an Strahlern gesenkt werden. "
I don't see how "radiators" fit in here - in fact the sense of the whole sentence escapes me.
Explanation: The term flood has already been suggested by e-rich, which I consider correct.
The 7-fache an Strahlern is really quite simple:
Previously (I assume) X floods were used to illuminate the object.
The new illumination system uses 7 times more floods. This is done to direct the light more precisely onto the monument (as David says, not to illuminate the surroundings).
The 80% energy savings are made by:
a) using energy efficient lamps
b) using a lower rating per flood,
I used to work for Philips, who provided the illumination for certain large objects in Egypt.
