What GU10 bulbs are people using with Fibaro dimmers?


(Conradj) #1

The dimmable GU10’s I’ve got from Screwfix currently are disappointingly bright when set low, especially in comparison to some Hue bayonet bulbs I’ve got elsewhere. Does anyone have any recommendations?

I use the Sylvania GU10 360lm ones from screwfix with Fibaro dimmers and they go nice and dim (3 bulbs per circuit).

If you have just changed your bulbs you should force an auto calibration on the Fibaro, as the min/max dimming levels may still be set to suit your old bulbs.

Thanks @RobinWinbourne. Wrt recalibration, can I do that from the app by setting #13 to 2 (as I have a bypass fitted)? How do I know when it is done?

Or do I need to press the button on the unit 3 times? Do I need to re-pair or do something else once it is done?

Apologies if the incantations are written somewhere and I haven’t found them.

Yep, just change parameter 13 to 2.

When you click done, sit back and watch the light phase up and down a few times.

Don’t press anything until it settles down (give it 2 minutes).

No need to re-pair or anything like that.

Great stuff. Do I need to set the parameter back to 0?

It auto resets to zero on the device, but yeah, on the ST app side you can reset it so you don’t force calibration next time you try to change a different parameter.

Did it fix the dim level?

I’ll give it a go tonight and let you know! Thanks for your help, got to say there are a lot of helpful people on this board :smiley:

I bought these ones but sadly I agree with you, they are very bright when on 1% and no amount of re-calibration seems to fix it… (posted so others are aware of the problematic bulbs)

Hope you get a bit more luck with yours!
