I worked at an architects house once, he had gone mental because someone fitted wide beam lamps, when he had designed his metre wide corridor to take extra narrow beam lamps, to create circles on the floor and arches on the walls, it did look cool when the right lamps were fitted and that was the original intention of the spotlights. you only really used spotlights, wallwashers, spaced around to highlight pictures,etc and most were originally tilt or eyeballs for that use.
Originally with halogen, there was about 10 beam angles, then only 3, then suddenly narrow beam lamps virtually dissapeared, wide beam became the norm and suddenly they were called downlights, one big manufacturer brags in there ads how you can save time and money by fitting less lights than there competitors for the same amount of light, due to the wide beam they claim to give out
