At first, except for fluorescent tubes, all our bulbs were incandescent. In 1996, after we came to New Westminster, we may have had one halogen desk lamp but Thomas Edison would have been quite at home with all the bulbs in our lamps. Then, during the following decade, we went completely to compact fluorescents. From the initial, twisty, bluish ones to the traditional bulb-shaped ones which were warmer. None of these lasted very long, especially in high-service locations. Finally, we've begun to move to LED bulbs over the past year or two.

My taste in light bulbs has rather quickly evolved. After yesterday's purchase, I got two more wifi-enabled, smart, coloured bulbs at Walmart. At last, after more than 150 years of technological stagnation, home lighting is improving rapidly.
