spotlight
A lamp that emits a strong, focused beam of light in a specific direction. It is used to illuminate stages, buildings, or work areas.

The spotlight illuminated the facade of the old town hall.
crystal hunter
A person who searches for valuable minerals and crystals in the mountains, especially in the Alps.
Der alte Strahler kannte die besten Fundorte für Bergkristalle.
The old crystal hunter knew the best places to find rock crystals.
emitter
In physics and technology, an object or substance that emits a form of radiation, such as radioactive radiation or thermal radiation.
Bei dem Experiment wurde ein schwacher Alpha-Strahler als Strahlungsquelle verwendet.
In the experiment, a weak alpha emitter was used as the radiation source.
'Strahler' (spotlight/emitter) is derived from the verb 'strahlen' (to shine/radiate). The ending '-er' forms a noun that can refer either to a device, such as a lamp that shines, or to a person, such as someone who searches for sparkling crystals.
Die Sonne strahlt heute vom blauen Himmel.
The sun is shining from the blue sky today.
You can recognize the meaning from context: if it is about light and illumination, it means a lamp. If it is about mountains and minerals, it means a person. In the context of physics or technology, it means an object that emits radiation.
Wir brauchen einen stärkeren Strahler für die Baustelle.
We need a stronger spotlight for the construction site.
In connection with lighting, 'Strahler' (spotlight) is often combined with the type of lamp, for example 'LED-Strahler' (LED spotlight) or 'Halogen-Strahler' (halogen spotlight). Typical verbs are 'einen Strahler installieren' (to install a spotlight), 'ausrichten' (to align), or 'einschalten' (to switch on).
Der Elektriker hat gestern die neuen LED-Strahler im Garten installiert.
The electrician installed the new LED spotlights in the garden yesterday.
As an object that emits radiation, 'Strahler' (emitter) is a technical term from physics and engineering. The type of radiation is often specified, for example 'Wärmestrahler' (heat lamp/radiant heater), 'Infrarotstrahler' (infrared emitter), or 'Alphastrahler' (alpha emitter).
Über dem Wickeltisch hängt ein Wärmestrahler, damit das Baby nicht friert.
A heat lamp hangs above the changing table so the baby does not get cold.
spot
A Spot and a Strahler are lamps that send strong light in a specific direction. Spot more strongly suggests a narrowly focused beam aimed at one point, while Strahler is the broader term for this type of lighting device. Spot is appropriate for targeted point lighting; Strahler can also be used for general directional lighting.
Der Strahler richtet starkes Licht auf die Fassade.
The floodlight directs a strong light at the building's facade.
Der Spot richtet einen engen Lichtkegel auf das Gemälde.
The spotlight directs a narrow beam of light at the painting.
