    I'm not sure what type your taking about, but if it's the kind that has a series
    of incandescent lamps, you could use a "DC Controlled Dimmer", 0-10V DC
    proportionally controls either 24, 110 or 240V AC. I haven't used one but I saw
    it on Jameco's web site, part #128901. www.jameco.com . Good luck.

    I want to be able to regulate the light in a aquarium so, that it
    looks like the sun is comming up in the morning and going down in the
    afternoon. The light in an aquarium is usualy fluorisent light. I
    know it must be able to dim fluorisent light, but I don't know how to
    do this. If it's possible I would also like to measure PH value of
    the water.

    In general fluorescent lamp dimming is not an easy task. Usually special
    dimming ballasts are required. Although I've not used it, you may want to
    take a look at the IR2159 or the IR21591 Dimming ICs from International
    Rectifier [noparse][[/noparse] http://www.irc.com ]. Punch the LIGHTING button, then FLUORESCENT.

    Please be advised this too is not a simple solution.

    I am doing the same with my salt water tank. I purchased a couple of electronic
    ballast from Lutron some time ago and they work great, 0-10V DC gives me control
    from about 10%-100% output. I just looked on Advance Transformer web site and
    found they have a new series of electronic ballast, the "Mark VII", that can
    control all the way down from 1% to 5%-100% depending on the lamp type. I may
    buy a couple of them to replace the units I own. I doubt that you will find them
    at a home center and will likely need to purchase them from either a specialty
    lighting center or an electrical wholesale house, you can get a supplier from
    Advance.
