More than 70,000 plastic bottle were used to create the recycled whale sculpture in Bristol.
The work depicts the tail of one whale diving and the head - complete with working blowhole - of another.
Stage Electrics, a provider of audio, lighting, staging and video equipment, teamed up with local creative design agency Codsteaks to provide the lighting support for the project.
According to Bristol Whales Project organisers, it represents the threat of plastic pollution in the world's oceans, particularly plastic bags and food and drink packaging.
Stage Electrics’ John Wallace, head of operations within its live events division, said: “Our team has worked with Codsteaks and At-Bristol to provide a low-profile lighting solution incorporated within the sculpture itself.
“The lighting solution also falls in line with the green credentials of the installation as the total power draw will be less than 10A once up and running. We built our own custom mechanical timer to ensure the lights are off during daytime.”
Bristol beat Brussels, Glasgow and Ljubljana to the title in 2015. It was established to reward cities which consistently achieve high environmental standards.
