The light is waterproof, shockproof, cordless and rechargeable. It without question redefines how we think about lighting. It can be used indoors, outdoors or even on a body of water for a stunning lighting display. It can be used in three modes. Static in white, red, blue or green. Dynamic with unlimited colors changing automatically. Or candle effect. All it requires is a six-hour charge to provide 8 to 20 hours of power, depending on which mode and intensity level is used. Suitable for outdoor use when the temperature is 32° - 104°F. The energy-efficient LEDs have an estimated lifetime of 50,000 hours. Bulbs (included): 16 white LEDs, 36 color LEDs. When used on the patio or deck, around and in the pool or on the pathways in the yard it creates magic lighting effects. Have several in different sizes and you can set the mood and effect for the evening. If that was not enough they can come inside and provide the same imaginative effects. The light comes with a "sit on" charger that allows you to have it plugged inside as an interior light. Just lift of, no unplugging and you have a portable light to take outside.
