We test the new products to find out who has the bright stuff

Some months into the new year, you will notice a big change in the lighting aisle of your local retailer or big-box store. The supply of 40- and 60-watt incandescent bulbs that accounted for 80 percent of the residential lighting market in the United States and occupied the most shelf space will be low. Their production will cease on Jan. 1. Once the existing inventory is sold out, it will be gone for good.
