Nite Ize’s new LED bulb replaces original AA-battery Mini Mag-Lite bulbs and comes in four colors, including night-vision-preserving red; the white LED bulb is also available in an upgrade kit ($9.99) that creates push-button control. Nite Ize reports that its bulb increases battery life to 20 hours (up from 5 hours for the incandescent bulb); using LEDs with C- and D-cell Mag-Lites produces even bigger battery-performance gains. From $8.99. Nite Ize, Inc., 800-678-6483, www.niteize.com
