Fixtures with diffusers (shades or glass covers) are best to avoid glare, while fixtures with bare bulbs can produce glare in your eyes from mirrors. Ceiling fixtures above mirrors should be directly over centre of mirror and be in proportion to mirror size for best results. Recessed downlights have benefit of being unobtrusive, but will produce shadows under eyelids, nose and chin unless placed close to mirror, spaced well apart and above a light coloured surface they will bounce light back upward to remove shadows. General lighting from recessed fixtures will serve to illuminate spaces, cupboards and bath, where some people like to read and relax. There are also waterproof lighting fixtures now available suitable for showers. Bathroom lighting, including fluorescent lights @ SelectLighting UK.
Installing dimmer controls for these fixtures is useful as they give attractive low levels of lighting for evening and allow you to adapt lighting to your mood and requirements. Candles can be added for that extra relaxing bath to soothe away daily strains and add intimacy.
Safety Lighting and Lights for Bathrooms
Firstly it is important to understand rating by which bathroom and some outdoor lights are classified. IP rating stands for 'Ingress Protection' and is always followed by two characters. The first character specifies degree of protection against particles or solid objects. Starting with 0 for no protection to 8 for a light which may be totally submerged in water up to specified depth. The rating which interest us are IPx4 (x is used in this case because there is no requirement in regulations for a level of dust protection). Lights sold as IPx4 will have been tested for protection against water splashing from any direction.
Zone 0 is inside bath or shower itself and any fittings used here must be low voltage (max 12V) and be rated IPx7 which is total protection when immersed in water.
Zone 1 is above bath to a height of 2.25m. A minimum rating of IPx4 is required here.
Zone 2 is an area stretching to 0.6m outside bath and above bath if over 2.25m. An IP rating of at least IPx4 is required here.
Zone 3 is anywhere outside zones 0, 1, and 2 (subject to specific limits) and where no water jet is likely to be used there is no IP rating required.
The IEE Regulations do not make specific reference to wash basins but in opinion of The Lighting Association they should be treated as Zone 2 (i.e. IPx4).
