Plow and Hearth team comment:
We're glad you’ve found the Aquaglow Jellyfish Hideaway to be as cool as we did—thank you very much for letting us know! We always aim for battery-operated lights (like our 865687 Starlight Bower), but had to make a decision when we found out 160 lights put too much of a drain on a battery pack. Since we really, really wanted the captivating effect created by all those super blues, our best recourse was the electric adaptor with off/on switch. We will certainly take your comments into consideration for future product development as we strive to create products that are both user friendly and able to create truly magical spaces for all children.
