    Who would like a piece of this action for approx £120:

    You can specify 30 minutes for sunrise too as a £5 option.

    I think this is incorrect. As far as I know it is the ballast that determines this. There are dimmable ballasts available for fluorescent tubes but they are very expensive. If you search the internet you won't find 'dimmable' tubes so either they make 'dimmable' ballasts for a non existent tube or they are all dimmable with the correct ballast.

    For 120 quid you could invest in a dimmable ballast or two - they start at around 40 quid, and start saving the rest for a lighting computer. I love the idea of them, but it really is a nice to have...

    I've been searching high and low for such a system for the past few weeks.

    http://www.climatecsystems.co.uk/projec ... es/12.html

    This looks promising, but I cant find a 0-10v dimmable ballast.

    I've found two types of dimmable fluorescent ballast; 1-10v, and DALI.

    I bought a 1-10v dimmable ballast, but wouldn't work with this, that I also bought http://www.elkay.co.uk/product.asp?id=3&catid=2

    This will work with incandescent lights though.

    I telephoned them and got a call back from one of their tech guys because I wanted to know
    if it would work with any of the dimmable fluorescent ballasts. The answer was that they havn't tried it, and If I try it, they'd like to know how I get on.

    I'm not sure I want to risk buying the DALI standard ballast to try it out.

    It would be great it it did work - the elkay dimmer looks very neat. I've thought about using it with alternative (either incandescent or halogen) lighting and then have the fluorescents on a seperate timer to come on, then the dimmable ones to go off, as in the original post.
