3 things to know before you buy your next lightbulb

Two years ago, under pressure from the U.S. government, lightbulb makers stopped manufacturing the humble incandescent bulb. You can still find some on the store shelves, especially specialty and 3-way bulbs, but standard 40/60/100-watt A19s are no longer available. Unless you stockpiled a lifetime supply of incandescent bulbs, you're probably in the market for replacements. Maybe you've already bought a different type of bulb and aren't happy with it. That’s pretty common, by the way.
