In an effort to save time, energy and money 169No 250W sodium luminaires were replaced one-for-one by the Glamox Limited i80. This gave the area a number of major benefits; energy reduction from 407,000 kWhrs to 283,000 kWhrs reducing annual cost from £42K to £29K; lamp life of the i80 is >50,000hrs where as the son lamps were being changed every 10,000hrs giving considerable savings in maintenance time.
It has been calculated a payback of 1.9 years on the over all capital outlay as well as giving improved lighting levels and a better quality of light for the passengers.

Recently a major upgrade to LED lighting has been carried out, in cooperation with Glamox Limited. The project includes a variety of key locations at the airport, such as terminals, control posts, car parks and more.
Important cost savings
This investment in the latest energy efficient technology will contribute to improved passenger ambience, and at the same time reduce the airport’s energy and CO2 consumption.
Heathrow has set a target to reduce it's absolute CO2 emissions from fixed sources by 30% on 1990 levels by March 2020. Significant savings will also be made on maintenance costs:
Heathrow, a major hub airport, has particularly high costs of access for maintenance. In all areas maintenance can only be carried out during a few hours at night. The airport’s new LED lighting solutions are virtually maintenance free, so that 100% lighting levels can be upheld without cumbersome and time consuming light source changes.

The survival training unit in Lohja has top-quality equipment, even by international standards, and offers unique conditions for comprehensive learning. The equipment includes a helicopter with a rescue hoist, self-balancing life rafts for 4-101 people and rescue chute systems. Lohja has the only facilities in Finland for Helicopter Under Water Escape Training (HUET). The hall wall has been modelled after a side of a boat and includes a net for climbing, and other authentic rescue equipment. The pool is used for training 3 000 - 5 000 seafarers every year. The nearest similar training location is in Denmark, which means that Meriturva also has many customers from abroad, mainly from Estonia and Sweden. "We train, for example, shipping company staff, rescue staff and students from maritime academies. The training is available for everyone and our customers range from canoe groups to astronauts" says the Equipment Manager Michael Blomqvist from Meriturva. The training hall was built in 2002 and renovated in summer 2018. As a part of the renovation project the lighting installation was upgraded to modern LED products.
Millions of Litres of Water
The training pool is four metres deep, 43 metres long and 27 metres wide. It's the biggest indoor pool in Finland and can take up to 4.7 million litres of water, which meant that it took ten days to empty the pool for the renovation. Water is a difficult element when it comes to designing lighting, as it absorbs light. The pool is efficiently lit with i90-P luminaires hanging from the ceiling, 15 metres above the water. The output of the three luminaires is 45 000 lumens. Of the four i90 lighting options, the medium beam luminaires were selected. The protective glass is heat-soak tested hardened glass, which has been treated on both sides in order to guarantee good light penetration. "The pool area offers various challenges for lighting, for example the humidity. The i90 lights are the most effective and durable choice for these conditions", says the Electrical Designer Pasi Tamminen from Sähköinsinööritoimisto Ahonen Ltd. Glamox provided the Meriturva pool building with all the new light fixtures. "I have used Glamox products for years and I know them to be reliable. Using only one lighting supplier also makes operating easier", Tamminen states. There are additional MACH 2 floodlights installed to offer more effective lighting for the survival training. Installed below the walking platform, they are long-lasting and can withstand the challenging conditions. The training and equipment area next to the pool is lit with the durable and efficient i80 luminaires, hanging from the dark grate ceiling.
The high-quality and glare free lighting ensures unobstructed visibility for both rescue procedures and equipment and gear testing. After each training course, which last between one and five days, the staff checks the condition of the equipment before it's used again. "Safety comes first for us and everything has to be in perfect working order. After the training course, the technical staff washes and dries the rescue overalls, pack the vests and look after the equipment", Blomqvist explains. The training is carried out in variable and realistic conditions. With a push of a button, the pool will be taken over by waves over a metre tall. The wave machine produces seven different types of waves, which is extremely rare. The wind machine will produce wind up to 30 metres per second with rain beating on your neck. While the helicopter is hoisting up the evacuated people, rotor sounds blare from the speakers. The evacuation training also includes rescue in the dark. "The old lights took a long time to regain their full power. Now the LED lights relight the space in an instance. The space is now better illuminated, and the lights don't blind even those who are floating face up on the pool", Blomqvist continues. The cool white light of the 4 000 kelvin LED luminaires is also an improvement to the slightly yellow light emitted by the discharge lamps. The robust and long-lasting LED lights make lighting maintenance easier in the tall pool building.
Kemi SnowCastle has attracted winter tourists since 1996. Now it's possible to enjoy snow and ice round the year, as the new main building houses a “snow experience space” with -5°C temperature all year round. The building also provides numerous other services.
”The SnowCastle operates all year and offers versatile restaurant and meeting services. In between meetings, one can drop by the ice room to cool down, to play in the snow or to have a go at the ice slide" says Susanna Koutonen from Kemin Matkailu Ltd.
The main building was opened in March 2019, on the 150th anniversary of Kemi.
Clean white light
The lobby of the two-storey building has a blue reception desk which looks like it's made of ice cubes. The high glass windows in the lobby and the shop windows are decorated with snowflakes.
“The colour temperature of the light in the room next to the experience space is mainly 4,000 Kelvin, which coincides with the snow white of the wall and ceiling surfaces,” says Seppo Penttinen, electrical designer at UpNet Engineering Ltd.
The ice cream parlour serves delicious ice cream sundaes, and the café serves drinks with ice flakes, amongst other things. From the lobby, there are stairs to the viewpoint restaurant which seats 300 people. The ice cream parlour, the restaurant, the café and the spa section are illuminated with Glamox D70 downlights.
"We were already familiar with the Glamox products, and we knew they were first-rate and reliable. The purchasing and the installation of the light fixtures for space was very easy. Everything worked flawlessly", Penttinen says.
The SnowCastle's large kitchen and cooking areas are illuminated with C63 square lights, embedded in the ceiling. "Cooking requires good, glare-free and even lighting. The IP55 enclosure ensures that steam from the kitchen does not penetrate the lights. The surfaces of the lights are also easy to clean. Good impact resistance ensures that the light fixtures can withstand impact so parts of it will not be scattered around the space, ”Penttinen explains.
The ice restaurant in the snow experience space is decorated with a fairy tale castle theme and it's the perfect venue for weddings and other events. "The venue offers princesses their fairy tale castle wedding with an ice sculpted pumpkin carriage and everything", Koutonen says.
Lights as part of the interior
The lights in almost all the areas attached to the main building are connected to the DALI control system.
The DALI system allowed us to create a versatile operating system and the light dimming feature has proved to be very useful. The wall panels and the operating system are equipped with automated settings, such as the northern lights setting which dims the space with a press of a button. The light levels can also be adjusted by hand", Penttinen explains.
”It's important that the lights can be adjusted to suit everyone in the work space. Some prefer to work in better lit areas than others", Koutonen says.
The office space, the souvenir shop and the reception area are illuminated with C90 and C95 module lights. Their clear and minimalistic shape lights every corner of the space. "The light fixtures are also interior elements in these areas and an important part of the architecturally stylish space,” Koutonen continues.
The technical spaces, service rooms and the safari service areas are illuminated with i60 lights. The i80 and i85 lights are fitted to the high ceilings of the maintenance areas and the loading bays. They are extremely durable and efficiently light the work areas.
Clean energy from nature
The experience space is 400 m2 in size and contains more than 100 000 kilos of natural ice.
"Many of our foreign visitors have only seen ice in their cocktail glass. Here they get to marvel at the enormous ice cubes cut from the sea and the river. We are also telling a story about the freezing of the Finnish waters and the clean snow", Koutonen rejoices.
Renewable energy and sustainable energy use are the corner stones of the SnowCastle area operation.
There is a solar plant on the roof of the main building. The buildings are heated with geothermal heating and cooled with geothermal wells. Waste heat is salvaged and used to heat the water.
"Kemi is the first city in Mainland Finland with the ISO 14001 environmental certification. We want to do our share to keep the city green and produce as much of the energy we require as possible", Koutonen states.
