LED Light Source installed at Baily Lighthouse

Application: Lighthouse Lamp
Products: Lighthouse LED Optics
Location: Ireland
Site: Baily Lighthouse, Howth Head, Dublin Port
Design Concept

Baily was previously fitted with a 100V 1500W lamp. These lamps were designed with large tungsten filament cage diameters to provide an electric light source which matched the original Acetylene mantel and PV burner diameters hence preserving the optical efficiency of the lens. Until now it’s been impossible to modernise the light source to take advantage of the next generation of low power LED emitters. This is because LED arrays of sufficient intensity within a small enough diameter have not been available.

With recent advances in surface mounted LED technology it has now become possible to create a composite light source of the required diameter to work efficiently with the traditional lens optics.


The UK General Lighthouse Authorities R&RNAV have recently developed a new light source for this purpose, which is now manufactured by Sealite under license. This is suited for both flashing applications in drum lenses and fixed character applications in a rotating optic such as the application for the Commissioners of Irish Lights at Baily Lighthouse.

The new LED lighthouse light source now achieves an effective range of 21 miles and offers the best optical gain for solarising traditional prismatic lens stations. With power consumption of just 78 watts @ 24 volt DC the solution outperforms all other LED solutions. One additional advantage of the new light source is that individual LEDs can be switched off in unwanted directions (eg. over land) saving additional power.

What Our Client's Say

On behalf of Karachi Port I am pleased to acknowledge your good service and provision of the new SL-75 solar marine lanterns installed by your firm in the harbour channel at Karachi Port. The new lanterns are very feasible and useful and equipped with the latest navigational technology.

[Re: Sealite SL-LED Lightsource at LaCorbiere Lighthouse], We were impressed with Sealite’s solution which provided a modern, reliable and efficient light source whilst remaining sympathetic to the lighthouse’s heritage and significance as a local landmark, but most importantly to improve upon reliability and to continue its vital role in aiding the safety of navigation in Jersey’s waters, as it has done for nearly 130 years.

[Re: Sealite Wins Duke’s Choice Award for Java Technology & the Environment – Sealite GSM monitoring & control system]. The team at Motorola were extremely impressed with Sealite’s innovative integration of the G24-Java wireless module in their GSM Monitoring & Alarm System.

As one of your new distributors (Belize and Honduras, Waller Marine Belize LTD), I would like to express my congratulations to you and your people in providing reliable, dependable and inexpensive products. Formerly we were distributors for a Canadian made product but these were found to be too expensive for the market and also offered only difficult and complicated programming. Our first order of lights from you (SL15’s) took only four days to arrive from Aussie Land, when I opened the box they were still flashing. I tested a SL60 (white) for four days (steady on) before it required a recharge…remarkable. I will be placing another order shortly. Keep up the good work.

[Re: Installation of WindTalker for kite-surfing club], The WindTalker™ is a big success here in Cyprus, thanks to your after sales support the unit is now functioning perfectly.

-Christophe Meletiou

We choose to sell Sealite … this is a long story, well we treat Sealite as our own and the relationship we have developed with Jeff and Chris and their attitude and commitment towards growing Sealite to this stage is remarkable. We feel at home when talking to them and the staff of Sealite and this in turn gives us more security and strength in selling products in India.

[Re: Sealite Solar-Powered LED Area Lighting system], We chose the Sealite system for the Jacobs Well Queuing Pontoon due to our previous experience with Sealite’s product, its durability and construction.

-Peter Taylor

I just wanted to say thank you for the light and bracket Sealite supplied to Birkenhead Marina. As the other lights (old ones) need new batteries I will be replacing them with new lights from Sealite and the same brackets that you supplied with the light we received last week … Your product is excellent and the system of setting the light is good also. Thanks again for all your trouble.
