Just acquired my first set of Hue lights (E27 type) and to my disappointment when I put them in my bedroom ceiling lamp they do not turn on. However If I try by putting them in a ceiling lamp in the kitchen they turn on just fine.

How can I debug this? Is my ceiling lamp to old and reject LED bulb? Can there be any electrical problem with my bedroom ceiling light wiring ?

Note that all my lights are E14 type and I'm using E14 -> E27 Adapters. I thought at first the adapter was broken but it's not the issue because it works fine on my kitchen lamps.

(I also have a desk lamp E27 type in my bedroom and the bulb works fine in there as well)

This is a picture of the socket

    There is a sticker indicating that the lamp must be a particular shape. Does the Philips Hue bulb have that shape? Fair chance it's bottoming out on the lamp bezel and as a result, is unable to screw in all the way. – Harper - Reinstate Monica Mar 25 '18 at 20:45
  • My bet is on the adapter not making contact in the bedroom fixture. ? – Alaska Man Mar 25 '18 at 23:39
  • @DanielGriscom UK. Here is a picture of the normal non led bulb that work (on the right) compared to the Hue + adapter. They look pretty similar to me. The adapter has even more point at the end so it should technically make more contact ? imgur.com/a/QNu43 – Marco Mar 25 '18 at 23:51

    Socket looks damaged. Does the lamp have a dimmer? If so, dimmer may not be compatible. – Mark Maunder Mar 26 '18 at 7:13

It was a faulty chandelier (very old) ceiling lamp. Not enough power was ending up in the bulbs. Working fine for ordinary bulb but not for led
