Available in six styles, the Modern Lantern cordless table lamps are notable not only for their untethered capability, but also for their tasteful designs (we're most smitten with the Jade style). The lamps are rated for at least 12 hours of illumination per charge (an additional battery pack can be purchased separately), taking about 2.5 hours to fully recharge.
At about 6 lbs. these lamps are easy to move around the house, making them a good option for dark spaces in homes and apartments (hallways, entries, corner of the home office, etc) where outlets aren't readily available. Prices range from $240 to $320, depending on the style.
