If you've ever been in a North American hotel room, you will know they are not big on lights. Rooms are often very dimly lit. This preference for gloom seems to pervade residential addresses too and one of the first projects we have undertaken in the new house is to replace all the light-bulbs. There were a lot of them, most being inappropriate choices for the socket into which they were inserted (which resulted in some very corroded fittings) and almost all having very low wattages. Replacing them with appropriate and brighter bulbs has made a huge difference to the level of light in the house, all for under $50. Here's the old ones...now in the trash!
