The best description for this handy Vase Light is POWERFUL! An excellent way to light up centerpieces without taking up a lot of room, this little dynamo puts out an unbelievable amount of light! It's a 4.75" square by 1.25" high and it has 16 pure white LED lights in a clear acrylic case. Fantastic for accentuating centerpieces and perfect for square footed vases like the popular Eiffel Tower Vases. Just place your centerpiece on top of this incredible light and you'll transform the look from OK to WOW! This would also work quite well as an up light for artificial trees or floral arrangements. LED's stay cool to the touch so no need to worry about overheating - just relax and enjoy your event. This light features an on/off switch on the side of the unit and it runs on 3 AA batteries (not included, replaceable). Each fresh set of batteries will provide 8 to 10 hours of life for this light. Seriously, don't look at this when you turn it on!
