How do you guys change from B22 bulbs to E27 bulbs? All my current pendant fittings are standard bayonet B22 fittings. I'm going to change all these to Hue (or Tradfri) bulbs. I could go down the route of getting B22->E27 converters for each fitting, but this is a pain, as I can't find a bricks & mortar retailer selling these (excluding Ikea, as that would mean a special trip). Or I could go down the route of changing the B22 fittings for E27 fittings, but again can't find these freely available. Therefore, has everyone gone for online purchases of the required fittings (if so, where from?), or am I missing something?
