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.
DO NOT USE A B22 TO E27 CONVERTER!!! You can put a bayonet bulb in either way and it still works because the two pins are underneath. The E27 only has ONE pin for live, BUT, put a converter in one of the two ways and the screw section may be LIVE - you might be able to touch the outer live area as you screw in the bulb.
