I've had the same thought as Metchosin, but as I see it, the bulbs are mostly heating the ceiling, where I rarely go, unless someone upsets me. Baseboard LIGHTING might work.....
Downlights are popular here. Stupid things let expensive heat out into the roof-space.
When I was a lad, my father made bed-heaters (No electric blankets in those days, for the likes of us, anyway) from 1'cube buscuit tins with a 100W bulb inside. Lovely. Came in handy if we had to work outside at night, too. Take the lid off, light and reflector.
No mug, my dad.
