Liquid lamp filled with multi-coloured jelly-like balls. Fill the tank with water and then flick the switch to illuminate the colourful LEDs and start the water current that makes the balls bob up and down. As the colourful orbs move they glow and tumble around each other. As such, this light makes a very effective demo line that is sure to catch your customer's attention as they approach your display.
