LED lighting systems on Royal Caribbean Quantum-class ships provide substantial energy savings

Promoted as the world’s first smartships, Royal Caribbean International’s environmentally friendly Quantum-class cruise liners - Quantum of the Seas and Anthem of the Seas - have set new standards in terms of energy-efficient onboard entertainment lighting systems. Now the numbers are in and the savings is even greater than expected.

When Royal Caribbean recently compared energy usage of the theatre show lighting system onboard Quantum and Anthem - both with large LED lighting systems that include Elation LED fixtures - with a similar yet incandescent-based lighting system on its Oasis-class Allure of the Seas, energy savings on the Quantum-class ships was 76%-84% greater, numbers that even surprised RCI.

Some of the real world number comparisons show that energy usage for all the show lighting in the Royal Theatre was 386 Amps on Allure compared to 91 Amps on Anthem and 62 Amps on Quantum. As the measurements were done at full on, actual median savings is even greater - more than 90% - as the LED lights only use power when light and color is needed while discharge lamps run at 100% when a show is running.

Royal Caribbean International’s Christopher Vlassopulos - who coordinated the design and specification for all the entertainment equipment in the ships’ public spaces, including the entertainment lighting systems - explains: “By switching from incandescent to LED we realize millions of dollars in savings over the lifetime of Royal Caribbean ships and on Quantum and Anthem we’ve also already benefited from the lower maintenance involved,” which is no small matter as RCI ships operate on busy 24/7/365 schedules.

Savings extends to other areas as well. HVAC requirements have also been reduced and the electrical distribution costs are much lower and more efficient due to less cabling, fewer connections and no dimmers. When combining the energy savings with the savings in maintenance and operational costs, the total cost delta between Allure and the Quantum-class ships is substantial.
