Almost all cruise vessels have a spa complex, often including a gym facility. Health and physical fitness are becoming more and more important for people and with the variety of food offerings on-board a cruise vessel, the spa and gym offer an excellent balance for the passengers.

Different areas on a ship require special demands on the lighting
Whether a passenger receives a beauty treatment or wants to enjoy a workout session in the gym room, one of the most important factors is to feel comfortable at all times. This can be achieved by installing suitable lighting and modern designs of luminaires in their surroundings. For example, this may also include installing vibration-resistant luminaires or lighting with reduced glare light output. In addition to the aesthetic aspects when selecting a luminaire for spa areas, high humidity and the potential for water ingress raise the bar for the technical specification of the light fittings. 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.

Important factors when working with lighting solutions for Spa areas:
- Functionality and comfort.
- Mechanical design/impact resistance.
- No maintenance and reduced power consumption (high energy efficiency)
Functionality and comfort
For a harmonised style in spa areas, the luminaires must match the overall interior design, including both ceiling- and wall-mounted luminaires. Light fittings for different areas in the spa can be provided in a similar style. A suitable Kelvin factor for lighting ensures a good balance between the light output and comfort for human eyes. Flexible light distribution can be provided using adjustable technology combined with dimming functions such as analogue, Dali or phase cut. This results in a functional and relaxing atmosphere. The colour-rendering index (CRI) factor should be above 80 in order to provide good quality light. Glare is an important factor in ensuring a comfortable environment for the passengers. Glamox luminaires provide features such as trim rings, décors, diffusers and unique reflector designs to limit this glare. Lighting designs can be optimised by using light calculation programs such as Optiwin® and by using high quality light luminaires that will limit the effects of shadowing.

Mechanical design
High humidity in spa areas puts a strong focus on using corrosion-free materials and a high protection from water ingress (IP grade). The luminaires must withstand frequent and regular cleaning. Low ceiling heights in spa areas may require low surface-mounted or recessed luminaires that are designed to fit different ceiling thicknesses. All plastic parts should be flame-retardant materials to prevent fire and toxic gases from spreading. The European standard, IEC 60092, requires that lighting installed inside spa areas should be designed for ambient temperatures of 45°C. As vibration can cause disturbing noise levels from the luminaires, it is also important to choose marine-approved products that are designed to prevent noise (i.e. vibration-resistant). Loose internal wiring due to vibration is dangerous and can cause short-circuits. The luminaires should therefore be designed according to the relevant marine standards. To avoid lengthy installation times and to reduce maintenance costs, Glamox recommends the use of quick, plug-and-play connectors. Dust protection is also important during the ship construction/fitting phase in order to prevent dirt getting inside the luminaires, as well as later during normal ship operations to prevent the ingress of dust and insects to the fixtures.

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.

All lighting products in a spa area should be designed in accordance with marine standards and regulations.
