Litho Circuits Lighting were tasked with upgrading the Street Lights in the historic village of Bunratty from Traditional HPS Lighting to Energy Saving LED technology, this project was to achieve a minimum energy saving of 50%.

Part of the challenge was to keep the 32 ornate light housings and improve the lighting levels while using a Colour Temperature of 2,700K so as not to spoil the ambiance of the area.

To achieve this task the old gear from the lantern was removed and replaced with a new 60-Watt LED gear tray. The LED Gear Trays used are SEAI Triple E approved with a 10 Year Manufactures Warranty.

HPS 150 Watt was replaced with a LED 60 Watt giving a 90 Watt saving per light, over 32 lights this gave a saving of 2,880 watts = 60% Energy Saving

2.8 Kw x 4150 Hrs/Annum x €0.155 (Cost per Kw/h) equates to a Saving of €18,011 over 10 Years

Payback time on investment 3.9 Years
