    I am posting this in case it can be of some use for people looking for dimmable LED oyster lights.
    Brilliant lighting supplies a dimmable slimline LED oyster light which is available through Bunnings.
    http://www.brilliantlighting.com.au/products/ceiling/disque/

    I have used some Disque fittings in non CBus applications and I like them because they have a colour temp similar to 4000k fluro and by my rough estimation an OK CRI.
    Actually 4200K claimed.
    As far as I am aware the lumens per watt are good and they supply a fitting up to 2800 lumens which I think is rare.
    The fitting has a very even dispersal of light with no hot spots.

    I have tried the 18W fittings in my office.
    Dimming levels go pretty low I guess about 10%.
    Previously I had 6 x LED downlight in a H pattern.

    I replaced the 2 centre downlights with the 18W 1750lm oyster fittings.
    Quite a bit more light for not much extra power consumption.
    They are slimline fittings and look OK for an oyster light.
    It was easy to mount them over the existing LED downlight holes and I installed them with flex and plug.

    Two 18W Disque lights on one channel of CBus Universal din rail dimmer.
    There was a few problems.

    The oyster lights glow in the off state.
    Since I don't sleep in my office I didn't bother too much but today I just installed 31LCDA which has stopped that.

    The office lights are on a sensor and sometimes they go off while I am sitting here not moving much.
    Occasionally the sensor will turn the lights back on again and the dimmer channel is indicating on but the lights do not illuminate.
    I'm not sure why but the dimmer is quite old.
    Turning the channel off and on again fixes it.
    I don't think the dimmer channel is overheating and I will wait to see if it happens again with 31LCDA connected.

    DO you have any experience with these on a leading edge dimmer (the non universal dimmers)?

    Hi Mick
    I only tried them on the universal dimmer.
    I hate using fittings without a lot of specs but the options for dimmable LED oysters are quite slim pickings.
    I just checked and they recommend universal or trailing edge dimmers.

    Some slight flickering noted recently at low levels after a period of time.
    I'd say don't use this product on CBus dimmers if you want low dimming levels in regular use.
    They are still functioning perfectly at full power.
    And thanks to 31LCDA still turn off completely.
    I only noticed the flickering after an extended time (hours) at low levels but that is not a 100% OK solution to sell to a customer.

    I think to recommend any dimmable LED it wants proper testing on the dimmer which is connected to and backing from the manufacturer.

    Since fitting the 31LCDA there has been no instance of the channel turning on and the lights not.
