Lumenworks has released its range of color-changing LED lamps known as Rainbow Star lamps, and these can be set to any of the seven colors you find in a rainbow. Each fixture won’t measure more than 10″ in height, and comes encased in a glossy acrylic shell that is able to float on a square metal pedestal. Each light also features a nightlight that’s been integrated into the base itself, lighting up automatically whenever the room goes dark – perfect for folks who hate returning home to pitch black conditions. A hidden AA battery compartment ensures you don’t need to hook up the Rainbow Star lamp to a power outlet at all times. A single charge is able to last up to 5 hours, which ought to be more than enough to last the evening till you hit the sack.
