HAVFISK Reduces Lighting Power Consumption By 50% With LED Lighting From Glamox

MIR LED 5000 LuminaireBy converting traditional fluorescent tube light fittings to LED lighting onboard several of its ocean going vessels, Norwegian trawler company HAVFISK has cut power consumption for lighting by more than 50%, while reducing the need for lamp changes, as the new LED lights offer at least five times higher operating life than the previous fluorescent lamps.

HAVFISK is Norway’s largest trawler company with 10 ocean going vessels. The company is currently in the process of changing from traditional fluorescents to LED lighting onboard its fleet. Several trawlers have already been refitted with LED lighting, by replacing the fluorescent tubes in the ships’ luminaires with ready-made LED kits developed and supplied by lighting solutions specialist Glamox.

“Changing from fluorescent tubes to LED lighting on board our vessels has reduced the power consumption for lighting by more than 50 per cent. In addition, we’ve reduced the need for lamp changes, as the new LED light fittings provide more than five times higher operating life than the traditional tubes,” says Eldar Vindvik, Technical Director at HAVFISK.

“The process of converting from tubes to LED in the Glamox luminaires is fast and easy. Basically, it takes no more time than a normal lamp change. In many of the lighting products, particularly the Glamox MIR luminaire, our crew members changed the lamps themselves while the ship was in operation,” adds Vindvik.

LED replacements
In the cabins and other interior spaces of the trawlers, HAVFISK chose to replace traditional luminaires by installing new LED lighting, such as the DL60 downlight from Glamox and the DLT RS(M) LED ceiling luminaire. “Here we are also achieving the same positive experience, with longer operating life, reduced energy consumption and improved lighting quality. Although these replacements were carried out by an installer, it was still a relatively simple task, as the cut-outs and cabling were the same as for the traditional luminaires that were being replaced,” explains Vindvik.

Freezing room challenges
HAVFISK vessels fish primarily for cod, haddock and saithe. The catch is processed and frozen on board the trawler. In the cargo hold, temperatures drop as low as -30°C and it is critical that these freezing temperatures are maintained and not increased by extra heat caused by light fittings. When using fluorescent lighting, additional energy is needed to offset the increased heat output from multiple banks of fluorescent lights. “Glamox recommended that we use its 1771 LED luminaire, which is suitable for refrigerated areas, and we are very satisfied with the solution,” says Vindvik.

“We can confirm that the LED lighting is performing as promised. By its very nature, LED is improving its performance, both on operating life and light output in colder areas. All in all, we are now benefitting from much better lighting quality in the ship’s freezing room than before,” says Vindvik.

HAVFISK vessels operate in harsh conditions and so must have light fittings that can withstand these environments. Glamox has shown a proven quality over many years in these harsh marine environments.  Improved lighting quality, high lamp quality, ease of replacement, a five-year product warranty and part-NOx fund financing are among HAVFISK’s reasons for using the new LED refit kits from Glamox.

“Glamox has provided us with excellent support for the process of changing from fluorescent tubes to its LED refit solutions. Glamox seems to have a very good understanding of this new LED technology. In addition, Glamox supplied the original fluorescent light fittings for the trawlers and so its LED replacement solution was designed for a fast and easy refit,” states Vindvik.

Partly funded by the NOx fund
The Norwegian NOx fund is a national initiative to reduce mono-nitrogen oxides, organised by NHO, the main representative body of Norwegian employer organisations. As Vindvik explains: “As a member of the NOx fund, HAVFISK received financial support to carry out the lighting replacements. Our calculations show that we are saving about 1,000 kilos of NOx emissions per vessel per year. The fund actually financed 30-40 percent of the complete replacement costs for us. The reduced fuel consumption due to the energy savings accounted for at least the same value. Overall, it turned out to be a good investment with a short payback for us.”

“As a bonus, Glamox offers a five-year warranty on its LED refit products, meaning that HAVFISK now has light installations on board its trawlers that can be considered as brand new. Glamox is renowned as being at the forefront of new lighting technology and for producing high quality products. This is of high importance for us,” concludes Eldar Vindvik.
