    A thread to discuss LED brands and their compatibility if any with C-Bus dimmers.

    Please note that this is only a community discussion and not official endorsement of any brand. Manufacturers can change processes and components with little or no outward sign, so a model that worked one year may not the next year and vice versa.

    With that said, feel free to report your experiences. Useful data includes the LED model, when it was bought, the city or state installed in, the unit type of the C-Bus dimmer, the number of loads on the channel, and your observations (minimum stable level, amount of dimming whine, etc).

    Hi

    I have success with the following brands using a universal dimmer:

    1. Ikea dimmable lamps - all work but need to limit output to 10%.otherwise flickering is seen.
    2. Philips shellbark range https://www.lighting.philips.co.uk/consumer/p/myliving-recessed-spot-light/5020131P0
    3. Philips bulbs 60W and 100W https://www.download.p4c.philips.com/files/8/8718696577370/8718696577370_pss_.pdf
    4. Govena LED strip driver te-dimm-led-60w-12v - These worked brilliantly really dimming achieved with no flicker.

    Hope this helps.

    Hi gte242,

    I have ended up buying the Phillips down lights after looking through different models.

    I am using the 8 channel LE dimmers and the Phillips rep has promised me that as long as I set a minimum 10% level, they will work fine.

    Hi Dave, how are your Philip’s down lights performing?

    Hi N.W.B,

    I have just powered up the system and trying to program it. I haven't done enough programming to use the dimming feature yet so can't really comment on that. However I do have a number of them that are glowing. I am going to get some 31LCD's to see if it fixes that.

    Back in May 2020, I replaced all our 12v halogen down lights with
    Philips Master LED MR16 (GU5.3) 7W Dimmable
    Have not had an issues with then at all.
    Last week, the T8 fluros were replaced with
    Verbatim T8 LED Tube 14W - 4 Foot (1200mm)
    So much extra brightness.

    Hello gang, I am an old, old CBus-er from the good old days. I have had C-Bus in my own home for almost 20 years. I am just about to knock down and rebuild. The builder has specified Clipsal CLITPDL1C2 downlights. I am wondering if anyone has used CLITPDL1C2 in conjunction with Leading Edge DIN rail dimmers. In a fantastic testament to the reliability of C-Bus I am intending to re-use much of my existing C-Bus gear. I have new dimmers and relay units but dimmers are not universal.
    I am also wary of input capacitance in the primary of the LED driver, so far Hanneco Viva 110 multi is the only reported DIM compatible (C-Bus) light that I can get details of input capacitance.
    I am resigned to having to use 31LCDA's so if the Clipsal CLITPDL1C2 works in conjunction with a 31LCDA then I will leave it at this.
    I get the feeling that everyone still tippy toes around this subject :)

    To make my questions a little more direct >
    Is the CLITPDL1C2 suitable for leading edge dimming ?
    Does anyone know the imput capacitance ( 240v / Primary side) of the CLITPDL1C2 ?

    From here I can make my own mind up with respect to C-Bus dimmer compatibility.
    Thanks in advance.
