Designed by Gingko, this amazing table lamp is very clever in its functional design, and opens into a lamp that is also a piece of art. The R shaped body looks like a 3D \'R\' when closed, but opens into an elegant lamp with a choice of either soft warm white, or a bright cool white, both colours being dimmable so you can use it as a vibrant task light, or as a more ambient background light. You can even use this incredible light as a travel lamp, it is powered by an in-built rechargeable battery, making it fully portable, or you can leave it permanently plugged in by using a USB plug adaptor (USB cable inlcuded) Powered by in-built 2500 mAh rechargeable battery with USB charging cableUSB charging or plug adapter power voltage: 5VNatural wood finish in WalnutRemote control or open-and-shut operatedDimmableColour light temperature: cool white (5000k) or soft warm yellow white (2700k)Rated power: 4.5WBattery life: 8 hours in brightest mode and 72 hours in least brightness modeCharging time: 3-4 hoursProduct size: when closed: 145 x 250 x 25mm / 5.70\'\' x 9.84\'\' x 0.98\'\' (L x W x H)Product size: when opened: 290 x 250 / 11.40\'\'x 9.84 (L x D)
