colour rendering index cri the quality of light a measure of the ability of a light source to reproduce the colours of various objects a light source with a cri of 100 ra would be perfect and balanced in terms of colour reproduction shading and contrast lumen depreciation l70 the deterioration in a lights performance after a time lumen depreciation values reflect the overall performance of a light source through its life all light sources suffer from lumen depreciation which can be accelerated by poor thermal conditions over voltage or incorrect application l70 is the operating time hours until the led lumen output is depreciated to 70 of its initial lumens ip ratings a fittings protection against dust and moisture ingress protection ip is a value given to products that have particular protection against dust and/or moisture the ip number is split the first digit represents the level of protection against dust particles while the second digit represents the protection against moisture

understanding bathroom zones iee wiring regulations bs 7671 2008 section 701 gives requirements for areas containing a bath or shower this document should be consulted before installation of appliances areas of the bathroom are split into zones as a guide only the requirements for luminaries in each zone may be summarised as follows particular care should also be taken with wash basins guidance for these are also contained within bs 7671 2 1 1 0 0 zone 0 refers to the interior of the bath or shower that can hold water requires electrical products to be low voltage max 12v and rated ipx7 254 technical zone 1 refers to the area above the bath or shower up to a height of 2.25 metres and requires a minimum rating of ipx4 splash-proof plus rcd protection ipx5 should be considered if water jets may be present i.e for cleaning purposes zone 2 covers an area 0.6 metres wide immediately next to and all around zone 1 wash basins should also be treated as zone 2 the minimum rating here is ipx4

emergency lighting what is an emergency light fitting emergency light fittings include a battery as a backup power source that is continuously charged emergency light fittings can tell when the power has failed and immediately switch to using the backup battery the battery needs to power the light fitting for a minimum of 3 hours to conserve power the light output from the fitting is reduced often to 10 of the normal light output what are the different types of emergency light fittings maintained fitting – will operate as a normal light fitting and be controlled with all the other lights in the area however when the power fails the maintained emergency fitting will continue to operate but at a lower light level non-maintained fitting – is normally switched off with its batteries being continuously charged and a green led showing fully charged when the power fails then the fitting switches on using its battery supply non-maintained fittings are not part of the general

communication protocols communications protocols are the method of transmitting information to the light fittings phase dimming uses the mains alternating current ac to reduce power to the light fitting by cutting out sections of the ac supply phase dimming was designed for traditional lighting technology and is common in lower power domestic lighting but is unsuitable for commercial applications due to the larger power requirements the supply can be cut from the front of the ac wave leading edge dimming and/or the back edge trailing edge dimming dimming 240v ac leading edge 240v input • separate control wire not required • for lower power applications 1-10 volt analogue uses a separate control wire to notify the driver that the power to the leds should be changed the separate control signal is a direct current dc and can be adjusted from 1 up to 10 volts the voltage level is interpreted by the driver to set the led power separate 1-10v control wire may need screened
