I was moaning on Twitter the other day about hideous lightbulbs - the big stores are stopping selling old-fashioned ones tomorrow - that make every room look like a particularly bleak and demoralising institution, when @dbrown_esq, who’s a tv and film production designer, told me about Filament Lightbulbs, who import and sell beautiful Swiss-made, er, filament lightbulbs. These are lovely objects in their own right and make *the* most beautiful, flattering golden light - the kind of light you’d imagine glowing from a wonderful house in the distance if you were a weary traveller in a story, or the kind of light you can see in every other hip restaurant in London. They are not at all cheap, but I’m told they last ages. I just took delivery of mine and honestly, they’ve transformed the rooms in question. I realise this is a bit niche, but I’m obsessed with lighting. Also in a way they are economical, since I’m not going to leave the house again (very good effect against skin, these bulbs. You really need a chaise-longue to go with them, and maybe a satin gown).
