Pool areas

Cruise ship sun decks have always been popular hangouts for passengers, but the original "one deck, one pool" mindset of the 90s has changed tremendously. Cruise lines are designing pool areas that mirror land resorts, the best of which have always offered fabulous pool and sun bathing areas. Many of the cruise vessels also feature outdoor cinemas at the pool areas. As with all areas onboard a cruise vessel, pool areas have special demands on the installed lighting equipment. The required lighting solution must operate in all weather conditions. A good lighting solution will also provide a safe working environment. When using LED strips for decorative lighting around pool areas, an IP class of IP68 should be used.

Different areas on the ship require special demands for lighting
Pool areas that don’t have a sliding rooftop are exposed to all weather conditions. This means that as well as achieving a reliable and even distribution of light output, it is also important to achieve the correct light colours, light intensity and a robust, stable light fixture for long term reliability that withstands the harsh conditions present in pool areas. Using the most appropriate material for the light fixture is important in order to ensure robustness and longer operating life of the fixture.

Important factors when working with lighting solutions for pool areas:

- IP class (IP68).
- Mechanical strength/impact resistance.
- No maintenance and reduced power consumption (high energy efficiency).
- Light quality.
IP class 
The challenge for pool areas is not only to protect the light from rain and spray water, but also that the light fixtures can survive intensive cleaning, using brushes, chemicals, other tools and often high-pressure cleaners.

Mechanical strength
Using the correct combination of materials in the luminaire is critical in order to ensure robustness and a long operating life. Materials are particularly important here and should be selected to withstand high shock and vibration. Especially for areas where heavy vibrations are present, Glamox recommends the use of LED light fittings. LEDs withstand shock and vibration due to the design of the diodes. No additional vibration suspension is required. A wide range of ambient temperatures is also an important requirement. Cruise vessels are able to navigate around the world. Ideally, the light output and light quality should be consistent across all temperature bands.

No maintenance and reduced power consumption

An important requirement onboard a cruise vessel is to install luminaires that are virtually maintenance-free. This reduces or eliminates the labour costs primarily associated with the maintenance, servicing and replacement of luminaires in difficult-to-reach locations. The luminaires should consume as little energy as possible in order to reduce the size of power generators, save energy and minimise pollution. 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.

Light quality

In pool areas, the light output quality is important due to visual perception and to enable the crew to distinguish between different colours and details.  The colour-rendering index (CRI) should be above 80 to enable differentiation and to see true colours.  To avoid shadowing and reduce glare (UGR), a proper light calculation should be undertaken and luminaires with homogeneous light distribution should be selected.

All lighting products for pool areas should be designed in accordance with marine standards and regulations.
