The Best Bet
Nobody thinks about a lightbulb until it needs to be changed, which usually happens every four to eight months. The new Enlux LED floodlight, however, keeps burning for about seventeen years because it uses the same technology as traffic signals and auto taillights. Available in three white and four color tones, it can replace 45- or 60-watt incandescent and halogen bulbs—which, in most homes, means track, pendant, and outdoor lighting ($89.95 to $94.95 at enluxled.com).
