Laundry

The laundry room on a cruise vessel should combine functionality with robustness. Not only should the crew be able to differentiate between different colours, it is also important to ensure the quality and water-resistance of the light fittings.

Different areas on a ship require special demands on the lighting
Due to high humidity and the potential for water ingress, as well as a need for robustness, laundries are quite complex rooms to design suitable light fittings for. As a result of the high demands placed on the quality and durability of its products, the Glamox Group operates modern assessment and testing laboratories in Norway and Germany for the simulation of a wide variety of environmental conditions including laundries.

Important factors when working with lighting solutions for laundry rooms:
 
- IP class (water ingress resistance).
- Mechanical/impact resistance and compact design.
- Light quality.
- No maintenance and reduced power consumption (high energy efficiency).

IP class (water ingress resistance)
The highest requirement is the IP class of the light fittings. The challenge here is to protect the light fixtures from ingress of steam, moisture and water. A minimum requirement is IP44 in order to ensure sufficient protection from the ingress of water.

Mechanical resistance and compact design

For light fittings installed inside a laundry on a cruise vessel, the European standard, IEC 60092, requires the luminaires to be designed for ambient temperatures of 45°C. Loose internal wiring due to vibration can be dangerous and can cause short-circuits. Therefore, the luminaires should be designed according to the relevant marine standards. To avoid lengthy installation times and to reduce maintenance costs, Glamox recommends the use of its quick, plug-and-play connectors.

Light quality
Light quality is important for distinguishing details. The colour-rendering index (CRI) should be above 80 to allow people to differentiate between colours and details and to see true colours. To avoid shadowing and to reduce glare (UGR, unified glare ratio) a proper light calculation should be carried out and luminaires with homogeneous light distribution should be used. The colour temperature preferred in a laundry should be 3000 - 4000 Kelvin, which will ensure a sensible balance between the light output and comfort for the human eye.

No maintenance and reduced power consumption

Maintenance-free, easy installation and various mounting options ensure flexibility and time savings, primarily because some lights may be located in areas that are difficult to reach or often with no access at all. The luminaires should consume as little energy as possible in order to reduce the size of power generators, to save energy and to reduce pollution/emissions. Therefore, LED lighting is recommended. LED luminaires are virtually maintenance-free, which means that cruise vessels with LED lighting will have lower operating costs compared to vessels with conventional luminaires. In addition, the reduced power consumption of LED lighting onboard has a positive impact on the cruise vessel’s Air Conditioning system, as less heat is emitted from the lighting, which means less AC power is needed and fuel consumption is reduced. The initial investment of the LED installation may be higher than a traditional lighting installation, but the reduced energy consumption and lower maintenance costs of LED lighting means that this price difference will be quickly recouped and payback on the investment is recovered quickly.

In a laundry, all lighting products should be designed in accordance with marine standards and regulations.
