Following their installation, the estimated savings are already being calculated as 35,724kWh annually, equating to 15.4 tonnes of CO2.

The Aquarium had been looking to change the existing halogen lamps in its public areas for some time.

Jim Farley, senior engineer at the attraction, said: "The original halogen lamps had a very short shelf life so we were constantly replacing them, plus the heat generation was a problem over some of the smaller chilled water tanks.

"We trialled various leading brands but none actually came anywhere near to the lux performance of the existing 35W and 50W halogens until we put Megaman's 7W LED GU10's to the test."

Providing a crisp cool white light, Megaman’s GU10's offer a life of up to 25 times longer than their halogen dichroic equivalent, three times less heat output and can be retrofitted into existing fittings.

The Aquarium's original electrical system included 240v, 12v and track fittings so it was agreed that changing some of the fittings would allow for a uniform GU10 mains powered system throughout.

This, in turn, would result in an easier option for the maintenance team to keep one standard lamp type in operation throughout the building.

The National Marine Aquarium is located in Sutton Harbour, Plymouth, and was opened in 1998. It is the largest aquarium in the United Kingdom and the deepest in Europe.

It's home to around 4,000 individual creatures of about 400 species, and houses aquariums, a lecture hall, a cafe, and a shop.
