It canbe thought of as an imaginary conewhose apex intersects the lamp face,and the breadth of the cone extendsoutwards to the point where luminousintensity has diminished to 50% ofthe centre beam value.BinningA process of sorting out individualAn approximate indication of thecolour impression created by a whitelight source. It describes how ‘warm’or ‘cool’ the appearance of the lightwill be. The unit of measurement isthe Kelvin (K). Sylvania LED lampsare offered in colour temperatures of2500-2700K (extra warm, similar toincandescent), 3000K (warm white,similar to halogen), 4000K (neutralwhite) and 6000K (daylight).LEDs. Most conventional dimmershave been designed for incandescentlamps and are therefore rated forhigher minimum loads (W) thanLED lamps consume. There maytherefore be some restrictions interms of functionality of dimmers withindividual LEDs – but when more thanone lamp is used to increase the totalloading, dimming becomes easier.the spectral range between visiblelight and microwaves, which producea heating effect when absorbed bymaterials. All lamps produce infraredradiation, but the quantity emittedby LEDs is far lower than othertechnologies and this makes themideal for reducing air conditioningload, as well as for the illuminationof heat-sensitive goods.LEDs according to their colour,photometric and electricalparameters. Raw LEDs cannot yetbe manufactured with the sameconsistency as conventional lightsources, and the colour differencesfrom one LED to the next can bevisible to the naked eye. This situationis handled by measuring 100% of theproduction and all LEDs having similarvalues are placed in the same bin.Sylvania takes only LEDs from certainqualified bins for the assembly of ourLED lamps, such that the consumerwill not be aware of deviations in thefinished product.CandelaThe unit of measurement for luminousColour Rendering Index(CRI)Indicates the ability of a light source toilluminate objects in their true colours.It is measured by shining the light ofthe lamp onto fifteen test colours (R1to R15) and measuring the shift fromthe true colour to the apparent colourunder the test lamp. The scores ofthe individual results are averaged toderive the Ra value. The higher theRa the better the colour renderingproperties. Daylight and incandescentlamps are the only sources to achieveperfect score of Ra 100. All SylvaniaLEDs have a good Ra >80, and certainpremium versions achieve Ra >90.DriversElectronic devices that transform thehigh mains voltage into a constantcurrent lower voltage for operatingthe LEDs.

The InternationalElectrotechnical Commission (IEC) iscurrently preparing an internationalstandard based on similar thresholdvalues.LumenThe photometric unit of luminousflux. Luminous flux is a measure ofthe total quantity of visible radiationemitted in all directions, which isweighted to take account of thesensitivity of the human eye todifferent colours.RecyclingSylvania LED lamps are extremelydurable and do not contain anySwitching FrequencyLED lamps cannot be switched onand off indefinitely, but are ratedto tolerate an impressive 60,000switching cycles or more.TCO (Total Cost ofOwnership)TCO includes all the costs over theentire life of a lamp or for a particularoperating time. It covers procurementcosts, electricity consumptioncosts, relamping costs and mayeven incorporate a reduction in thenecessary air conditioning load.
