I found it interesting that all the LEDs illustrated in the article assumed form factors of conventional screw-in incandescent bulbs, presumably using alternating current (a.c.). No mention at all of direct current (d.c.). Why do you suppose this is, when the thrust of the article was to highlight the comparative efficiency of LEDs?
