Sectored LED Port Entry Light with GSM Remote Monitoring and Control

Application: Precision Sectored Port Entry Light
Product: SL-PEL-05-GSM
Location: Singapore

Shell Singapore operates a refinery plant in Pulau Bukom, an island that is about 5km south of the Singapore Mainland. To aid vessels entering the refinery, they had cited a port entry light (PEL) on a nearby island. Troubled by the procurement of replacement lamps as well as the ageing of the hardware, Shell has to invest a lot of time and effort to ensure that the PEL was continually in working condition.

Project Overview

With the introduction of the Sealite 5 degree sectored LED port entry light into the aids to navigation market, Shell expressed interest in replacing the old PEL due to its small size and power efficiencies. With class-leading LED technologies, the Sealite PEL does not require focusing or re-lamping while in service, there are no moving parts and is a low powered option providing over 500,000cd at 30watts. Shell chose Sealite’s PEL to replace their existing light due to the huge cost saving potential the company would receive, therefore eliminating the need for the inventory of incandescent light bulbs. In addition, Shell now doesn’t have to schedule manpower to perform the replacement and corrective maintenance, saving much-needed maintenance costs.

The Outcome

The Sealite 5 degree PEL consists of ten LEDs to create ten precise sectors, with each sector giving an accuracy of 0.5 degrees (horizontal). Coupled with the optional GSM Remote Monitoring and Control, Shell is able to get a daily status of the PEL-05 automatically on their mobile devices via the SMS feature. Shell is also able to view and control the operation of the lantern, giving 24 x 7 live updates to the operators without having to leave the comfort of their office or home. The added benefit of historical data (30 days) showing the status of the PEL was extremely helpful in planning any preventive maintenance work on the PEL system. In conclusion, Shell now has a reliable light that will only need to be checked once a year as part of their standard maintenance regime.

[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.

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: 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.
