All lighting luminaires produced by Havells-Sylvania are designed, manufactured and tested under a quality assurance system in accordance with BS EN ISO 9001:2000, and are designed to comply with EN 60.598 under certificate number FM 01687. Also, the company employs an environmental management system under certificate number EMS 39002 that complies with BS EN ISO 14001:1996.
The European Norm Electromechanical Certification (ENEC) has been adopted as a common mark of conformity with European Standards. A mark issued by any single national approbation bodies implies compliance with all seventeen international bodies. The ENEC mark now replaces the national test house symbol, and is appended by a number indicating from which test house the approbation originated.
The designated product(s) is (are) in conformity with the provisions of the following European Directives:
|2006/95/EC and amendments||Directive of the European Parliment and of the Council of 12 December 2006 on harmonisation of the laws of Member States relating to electrical equipment designed for use within certain voltage limits.|
|2004/1 08/EC and amendments||Directive of the European Parliament and of the Council of 15 September 2004 on the and amendment approximation of the laws ofthe Member States relating to electromagnetic compatibility.|
|2009/125/EC and amendments||Directive of the European Parliament and of the Council of 21 October 2009 on the establishing a framework for the setting of ecodesign requirements for energy-related products.|
|2011/65/EU||Directive ofthe European Parliament and ofthe Council of 6 June 2011on the restriction of the use of certain hazardous substances in electrical and electronic equipment.|
Fittings and transformers are supplied primarily for operation on 230/240V 50 Hz. For alternative electrical specifications contact Technical Support
|EN 60.598||Class 1 – fittings comply with class 1 (l) earthed electrical requirements i.e. functional insulation in all parts and earth termination|
|Class 2 – fittings comply with class 2 (ll) double insulated electrical requirements i.e. complete insulation in all parts without earth termination. In the event of an electrical fault, no dangerous voltage can reach touchable metal parts|
|Class 3 – fittings comply with class 3 (lll) triple insulated electrical requirements i.e. Where protection against electrical shock relies on supply at safely extra-low (SELV) and in which voltages higher than those of SELV are not generated|
With defined limiting value for each class
According to the CELMA (the European Federation of the National Associations of the manufactures of luminaires, control gears and lampholders) classification scheme the following classes and typical ballast types exist:
Dimmable ballasts are classificated A1 if they fulfil the following requirements:
Electronic ballasts (conforming to CELMA energy efficiency scheme classes A1, A2 and A3) are major power savers. They even reduce the power consumption of ballastlamp circuits to less than the rated power of the lamp at 50Hz. This is caused by the increased lamp efficiency at high frequencies (>20kHz), leading to about 10% less lamp power and a decrease of the ballast losses
EN 55.015, EN 61.000 & EN 61.547
Fittings comply with radio interference suppression and electromagnetic compatibility (EMC) regulations
The resistive performance of fittings to solids and liquids is indicated by the IP (Ingress Protection) prefix followed by two numbers. The first number indicates the measure of protection against the ingress of solids. The second number indicates the measure of protection against the ingress of liquids
The resistive performance of fittings to solids and liquids is indicated by the IP (Ingress Protection) prefix followed by two numbers. The first number indicates the measure of protection against the ingress of solids. The second number indicates the measure of protection against the ingress of liquids.
The resistive performance of fittings to external mechanical impacts the IK code prefix followed by two numbers.
Performance cones indicate beam spread, ie. a narrow, medium or broad beam of light. The illuminance values given (lux/Klm) are the maximum values within the beam for horizontal planes at various distances below the luminaire. The beam diameter, ie. the approximate size of the light coverage, is also given. The cone widths are calculated for an illuminance at the edge of the cone of 50% of the maximum. By spacing luminaires at the beam diameter for the appropriate height, the combined effect of adjacent cones is to produce an acceptable uniformity along the centre lines between luminaires (figure 1).
Polar Diagram of luminous intensity distribution These provide a graphic representation of the distribution of light from a luminaire. Often referred to as polar curves, they indicate the intensity, measured in candelas (cd) per 1000 lumens.
The tables provided use luminaire Photometric data that has been measured and tested in accordance with British Standard 5225 Parts 1 & 3 ‘Photometric Data for Luminaires’. Additional photometric data can be provided upon request. All data is also available in CIBSE TM14, EULUMDAT and IES NA formats.
A complementary lighting design service is also available, to provide guidance and recommendations and to ensure lighting solutions are tailored to customer requirements. Supporting this service are the latest computer software facilities enabling accurate predictions and performance checks to be carried out
