LED Module 70 - Hellanor

Lighting designers may specify cool white forgalley areas and warm white where there is anabundance of varnished timber work instead ofhigh gloss gel coat surfaces.Enhancing interiors with attractive colour matched illumination.Hella marine offers highly efficient LED lamps with colour temperatures in the warm whiterange of 3000K, or white range of 5000K.Specialist LED selection and quality control ensures the colour temperature and colourrendering performance is matched across similar series. The result is a uniform colourtemperature and ambience throughout a vessel when different lamps are installed.Warm WhiteWhiteLight OutputFor an effective comparison of the differentproducts from marine LED manufacturers, manyfactors must be considered. The best lamp fora given application is no longer the one thatsolely meets a style requirement. Today, powerconsumption, efficiency, output and beam anglemust be considered together with light colour,shape, and the aesthetics and finish of thehousing itself.The following performance data is worthconsidering -Luminous FluxMeasured in Lumens (lm), luminous fluxdescribes the total quantity of light producedfrom a lamp. The higher the lumen count, themore intense the light output.Luminous intensityMeasured in Candela (cd), luminous intensity isthe luminous flux at a particular angle from thelight source. Peak candela occurs at 0 degrees,i.e. directly below a lamp.Rakino0956 seriesRakino0959 seriesIlluminanceMeasured in Lux (lx), Illuminance is equal toluminous flux divided by the illuminated area.One lux is equal to one lumen per square meter.Tiri0957 seriesPonui0771 seriesTiri0956 seriesPonui0770 seriesLuminous Flux (Lumens) / Area= Illuminance (Lux).orIlluminance (Lux) x Area= Luminous Flux (Lumens)If both the area to be illuminated and thedesired level of illumination are known, the totalnumber of lumens required can be calculated.Divide the total lumens by the output of theLED lamp under consideration to determinethe number of fixtures required to deliver thedesired light output.Waiheke0681 seriesWaiheke9076 seriesOblong9680 seriesWaiheke0681 seriesWaiheke9076 seriesOblong9680 seriesEg, A powerboat salon of 10 square meters andthe desired illumination level is 120 Lux, a totalof 1200 lumens are required.If the LED lamp under consideration has aluminous flux of 80 lumens, 15 lamps will berequired (1200 / 80 = 15).For further comparisons it is also important toconsider the beam angle of an LED lamp, andthe lux levels available at varying distances fromthe device. Narrow light beams may provideeffective intensity directly under the fitting, butmay not evenly illuminate an interior as the lightmay be too narrow with many shadows betweeneffectively lit areas.Easy Fit8560 seriesEasy Fit8560 series59
