    I am interested in some of the technical information to do with
    lighting, what goes on inside a ballast, how different ballasts work,
    efficiencies of fluorescent tubes, metal halide lights, halogen
    tungsten bulbs. Why some ballasts must be matched to the driven tubes
    in wattage, others do not. why I tie wires together if I am using a
    ballast that can supply two tubes if I am only using one tube.

    any recommendations?

    thanks
     
  2. There is no single book. To understand how discharge lamps work you
    can start with Electric Discharge Lamps by John Waymouth, MIT Press,
    1971. This is out of print but apparently still available from MIT
    Press as a reprint. You could also get a free copy of the Advanced
    Lighting Guidelines from http://www.newbuildings.org/lighting.htm, but
    much of this deals with applications, not operation.
    Well - all do in one way or another. However, some lamp/ballast
    systems are designed so that one ballast can operate lamps of more
    than one power rating.
    What? Certainly not for all two-lamp ballasts. In fact, I don't know
    of any where this is done.
    Waymouth will explain EM ballasts, but none of the above will tell you
    how an electronic ballast works. For that you will have to get some
    texts on power supplies or power converters or take a look at some of
    the hundreds of patents for electronic ballasts.

    In addition to Vic's excellent suggestions, check Chapter 6 of the IESNA
    Handbook (9th. Edition). The references at the end of the chapter are good
    sources of details. Ed Hammer (E.E. Hammer) of GE Lighting, for example,
    has written dozens of papers on fluorescent lamp/ballast operation.

    More recent than the Waymouth book is Lamps and Lighting by Coaton and
    Marsden. I think the 4th. Edition (1996) is still in print. There's good
    circuit and waveform information, but no circuit component values. Look for
    it in a technical library or used; it's high priced.
