      Has anyone noticed that the color’s are not accurate with these bulbs? When I select a deeper green, I get a very light green/yellow, and with a deep blue, more of a purple. Is this a common thing with these bulbs vs. the other Hue lights?

      Hi I have just had gu10 fitting installed in my bathroom so I can use hue bulbs except when I put my bulbs in, the ones that I took from my kitchen so I know they work, nothing worked, they blinked every minuet or so but nothing else and the app said they could not be found, I tried a normal gu10 led bulb and it worked fine, any ideas.

      These GU10 colour lamps do not fit my lamp holder. I thought this was an accepted international standard. The White lamps are fine. The units are 4 inline so to have two that fit and two that don’t is just plan daft.

      Is there an adapter available?

      I have the GU10 ambience bulbs and I am looking for an up and down wall light that will fit them?

      Does anyone have any idea?

        Can’t name any specific ones but I am sure there will be many that will be suitable, even with standard GU10 bulbs there is usually good gap between bulb and casing, so even with the additional length of the Hue bulb it should fit.

          Really struggling to find ip65 rated bathroom down lights that fit our white hue bulbs. They’re just a little too big for the glass cover on the light, really frustrating!
