Glad you like it.
Picture 1: I used a hazer to get the light beam of the torch. Key light was a bluefiltered (i think the moon filter from lee) LED Panel from left at about eyelevel. In the back you see a practical (oil lamp).
For the right side of his face I bounced a 1,2kw HMI against a reflector - which served as a rim light on his face and also gave some ambient light to the whole scene which otherwise would be massively underexposed.
Picture 2: Really basic setup. Softened 1,2kw and 575HMI shining from the outside through a window. I think we used a bit of fill light (just a reflector from the right side. Otherwise the practical bulb next to his head is doing a tiny bit of a rim.
Pircture 3: 1,2 kw HMI from left top bouncing on a reflector into the room to give bluish ambient light. Key light for the old mans face was a warm LED which is placed just right a bit above eye level . It should simulate the practical bulb which is hanging above.
The light on the younger actor is from a Bulb behind him. Otherwise there are to practicals which doesn't affect the overall lighting. My lighting concept was to have many light sources and still have the scene dark.
Sometimes I like to light more from a side axis to avoid ugly nose shadows. If you place your lights 1 meter next to the camera axis it often looks ugly to me.. but that's not always the case of course.
Hope that helps!
