I was looking to fit some Philips Hue LED bulbs, but they only come with Edison screw fittings (E27) and every light fitting in our house is bayonet (B22). I initially looked into using adapters but I was concerned about the quality and couldn't find a reputable brand. Is this something that I can change myself? For the avoidance of doubt, I live in the UK and I am not a qualified electrician.
it's usually pretty easy to change the fittings:
- make sure electricity is off (turn off the breaker that powers the light)
- double check the electricity is off
- loosen the screws that hold it up on the ceiling and keep the wires attached. Remember which wire is connected to the ground (bare/green or yellow green striped wire), live (red, orange or blue wire) and neutral (black wire) connections. If your house is newer then the colors may be different: green/yellow stripe for ground, brown/black or gray for live and blue for neutral
- connect the wires as indicated in the manual for the new fitting
- attach the new fitting to the ceiling
- put in new bulb
- turn electricity back on, if the breaker doesn't want to stay on you did something wrong and should inspect what you did wrong before trying to "fix" the breaker.
- toggle the switch and bask in your accomplishment.
It is quite easy as ratchet freak described. The only problem is if your old lamp shade or similar will still fit. E27 is wider.
