    Default Dimmable LED lighting

    There was a comment on the press release about wanting to know the lumen and beam angle values so here is a PDF with this info.
    Unfortunately the file is too big to attach here so here is a link to it www.casatech.eu/downloads/dimmable.pdf
    The lights come in three different beam angles 15, 30 and 60 degrees.

    Philips has just come out with AFFORDABLE-ish dimmable LED GU10 bulbs.
    http://www.lighting.philips.com/in_e...ghting&lang=en

    There are also cheaper variants using Cree available on eBay. Warm white is available. The Philips one is around 25-30 each.

    I am guessing the trick is that it basically has a wide-voltage input transformer built into it. Plus other electronics like the PWM driver etc of course.

    They are claimed to be able to dim all the way down to 10%, using a conventional dimmer... really?!

    yes but yes but the luminous flux is rubbish for the Philips. Our 3W are the same as their 7W.

    Toscal - are these fittings adjustable or fixed (i.e. can you direct the light beam of the fitting)?

    At the moment no but we are working on an adjustable version.

    Are these compatible with trailing or leading edge dimmers? Do you know how linear the dimming quality is and is it stepless (i.e. does it fade smoothly throughout it's range)?

    I'm curious to test these at home to see if they really do have the ability to replace conventional 50W 12V halogen spots, both in terms of maximum output and also dimming performance with my lighting controls. Depending on the linearity of the dimming I may have to adjust the dimming curve used by the dimmer modules to make it appear linear in use (i.e. 50% dimmer channel setting gives 50% light output) but in my case my controls allow that kind of flexibility.

    Are they available yet or is their an anticipated date for launch?

    They are available now, but we now have a waiting list of about 3 to 4 weeks.
    We have tested them on a conventional normal mains dimmer. But as yet haven't tried it on any type of electronic style dimmer.

    Just a quick update. The dimmable LED lights have had a bit of a setback. They are not that stable, seem to lose stability after a while.Needless to say we are working on a solution. We hope that this will only take a month to sort out. We will keep you posted.

    If I was to forego any dimming capability for the time being, is GU10 LED lighting a realistic option for my kitchen. If so which bulbs would you recommend?
