Thanks so much to all of you for all your wonderful ideas! I've asked form more information about the contents of the chapter, and what I got late last night was: "in dem Kapitel geht es um Fluoreszenzlicht, also künstliches Licht (Leuchtstoffröhren usw.), und "falscher Schein" bedeutet, dass es zwar weiß aussieht wie natürliches Licht, aber dass das Spektrum völlig anders ist als bei Sonnenlicht (oder auch Glühlampenlicht), nämlich nicht kontinuierlich." So, with this new information, I think that Helen's contribution gets closest. What do you think?

In the light (if you'll pardon the pun) of this extra information, I can see mileage for my second suggestion of duplicitous, but I also like Wendy's suggestion.
Other well-known English saysings keep coming to mind, and I am wondering whether anything can be re-spun to fit eg. Falscher Schein led me immediately to "Appearances can be deceptive"

unfortunately, that's all I have - the table of contents and the title page of the book. The title of the book is "Lügendes Licht - die dunklen Seiten der Energiesparlampe".

I have made a guess below, but without more context it is nothing more than a guess. What is the point being made in the chapter? How this relates to the title is highly significant in producing an appropriate translation for the chapter heading.
