The E27 fitting is the standard bulb socket that most people already have and it opens up something genuinely useful: the ability to choose a wall light for how it looks rather than hunting down a proprietary bulb that costs a fortune or disappears from stock. That matters more than it sounds. Wall lights do something that floor lamps and ceiling pendants cannot. They put light exactly where you want it, at the right height, without a wire trailing across the floor or a shade dominating the room from above. We’ve been looking specifically at designs where the fitting feels like a considered choice rather than an afterthought, where the shade, arm, or backplate has enough presence to contribute to a room even when the light is off. These work in bedrooms, in hallways, on either side of a fireplace. The bulb you choose changes the whole mood. These are the wall lights worth committing to.
