Hello everyone. I have a question that as simple as it looks it is making me doubt if I answered the correct solution.
A room is illuminated by 12 double fitting 85W fluorescent lights and I got to calculate the energy consumption.
I multiplied 12 x 2 because it says it is double fitting but I actually don't know if the 85W is for both of them or for each (it does not say anything specifying)

I would think that you are right to assume that each fixture has two 85W lamps, since the other option would be two 42.5W lamps to make the 85W, and there is no standard bulb that I know of that is 42.5W. Still, I've never heard the term "double fitting" in the context of lamps. Is that the question in English, or translated from another language?

My guess is that these are standard fluorescent fixtures, which typically hold two tubes. Some smaller (1" diameter, 48" length) tubes I have are 32 W. each. Longer and fatter tubes could be 85 W. apiece.

Yeah, doing more searching, "twin fitting" or "twin bulb" light fixture seem to be more common terms.

I assume this is for lighting in a museum dedicated to the topic.
