ENTRANCING ADDITION TO ANY MOOD LIGHTING!
on 28 December 2012
I saw a larger version of one of these in a local pub, it really was mesmerizing and I knew I wanted one. The movement of the jellyfish seems fairly authentic as the tentacles wave within the current - maybe not so authentic to warrant the sign explaining that they are not real - I digress. I was happy when I unwrapped one of these at Christmas to add to my bedroom ambient mood lighting collection.
The motor that pumps the water and causes the movement is absolutely silent and so the only factor drawing your attention to it is the elegance of the silicone jellies dancing within the uplighting of three LEDs; red, green and blue.
The silicone jellyfish are translucent and catch the LED light throughout to give the appearance that they are emitting the light, reaching all the way to the very tip of the tentacles. The light of the individual LEDs on the jellies causes an ever changing colour mix across the spectrum and as they move the mix is constantly changing. Each jelly can give the appearance of having several colours perfectly fading together at any moment. The water itself does not catch the light, which is a good thing as it gives more to the effect of them emanating the light, which in turn refracts to very subtly light up any nearby object with a wash effect. It really is subtle.
Important to note that if there is any air within the water it will not work properly, so you need to fill the tank to the very top and hold the jellyfish by the tentacles when you put them into the tank, using a chopstick or similar to push them down and shake free any air trapped within their shape or on their surface. Then just top up until brimming and push the little plastic cap into place. A tiny bit of water will spill out but this is needed to get all the air out.
Initially I found that there was too much air clinging to them and many air bubbles covering the inside of the tank, all of which caused them to float to the top and get stuck. I emptied it, gave it a clean out with boiled and cooled water - less impurities for the air to cling to - and refilled it with more boiled water. I soaked the jellyfish in boiled/cooled water for about half hour so they could take up some of the water and added them back. Without the air they move throughout the tank within the invisible current.
In terms of battery life the LEDs of course take very little energy, however I suspect due to the motor I have had to replace the 3 x AA batteries already and am on my second set in 4 days, but I guess running it for 8 hours a day would do that. Will be buying rechargeable batteries and recommend the same to you. It doesn't accept a mains adapter so batteries are the only choice.
Mine was apparently bought in-store but it is exactly the same make, model and boxed the same, and the dimensions on the listing match the one sitting on my desk.
The picture on this listing and on the box really do not do it justice as they are low resolution and make the water look murky. With boiled/distilled water and the plastic tank kept clean they do look really sharp!
