Notek P-Scheinwerfer blackout light
I would like to present to you the Notek P-Scheinwerfer: This blackout light was developed by Notek to illuminate larger areas like labor camps but also camps and runways in the field.
The light source is an Osram 100W incandescent lamp with BA20d base run by a transformer on mains or of a battery pack. There were versions for 6V, 12V or 24V available. (There was also an extremely rare version that runs directly on mains with a slightly different construction and different light bulb. I might show it in a future post.)
The employment of foreign workers and their accommodation in closed camps also poses new tasks for lighting technicians, especially in the case of prisoners of war and Russian civilian workers. The maintenance of the camp regulations and the securing of the camp inmates' isolation from the environment also require, among other things, reliable lighting of the camp aisles and the connecting routes from the camp to the plant.
The new NOTEK P-SCHEINWERFER can provide excellent help here. It was created for the air raid-proof illumination of workplaces in the open air. Its light beam can be limited in any desired shape, i.e. also in the form of a rectangular bar, as is necessary, for example, to illuminate camp aisles when the barracks themselves should not receive any light. The brightness of the light is almost the same both close to the spot where the spotlight is installed and at the furthest point of its range and is always air raid-proof!
The P-Scheinwerfer is fed from mains via a transformer. The light source is a 50W/6V, 100W/12V or 100W/24V special light bulb. It can be attached to a tripod (which we can supply with a cross brace for the transformer), fixed to the wall or on a base. However, the P-Scheinwerfer will always make the work of your security guards much easier and more reliable.
As usual with blackout lamps the light opening is covered by a hood to prevent any light emission into the sky. The hood also houses the light bulb. The light is directed by 2 mirrors through the light opening.
There are 4 ways to reduce/adjust the light output:
- Doors within the hood controlled by a knob on the top to restrict the light output vertically.
- A flap controlled by a knob on the underside of the lamp to restrict the light output horizontally.
- A removable metal sheet to prevent direct light from the light bulb to the second mirror.
- A diffuser in front of the light opening.
Typically the lamp was used with the metal sheet and diffuser in place. The responsible Luftschutzbeauftragte had to explicitly approve the removal of those pieces!
