Ledvance E27 LED light bulb, warm white - Verlichting

New LED lamps in a glow filament design as well as a replacement for halogen reflector lamps being phased out from 2016 are now available for the 2015/2016 lighting season\n\nOsram is starting with a range of further LED lamp developments for the new lighting season that traditionally begins in October. At the same time, the lighting manufacturer supports the efforts of its trade partners with a renewed LED competition for consumers.\n\nFor the current lighting season, Osram is launching a lamp type featuring state-of-the-art technology that looks almost identical to classic carbon filament lamps – “LED filament” is the name of the new technology where tiny LEDs are interlinked and surrounded by a glass bulb, as were incandescent filaments in previous years. All new LED Retrofit Classic from Osram comply with the demands of energy efficiency class A++, meaning they consume around 90% less energy compared to traditional incandescent bulbs, and have a 15 times longer lifespan with 15,000 hours.\n\nLED filaments feature 25 to 30 tiny LEDs configured in a line on a miniaturised PCB, and these are connected in series and surrounded by a phosphorous cast that gives the so-called filament its yellowish color. Osram technicians speak of “Chip on Cord”, based on the common “Chip on Board”. The glass bulb is filled with helium gas to protect the components, primarily the LEDs, from overheating, utilizing the chemical characteristics of helium for optimum heat dissipation.\n\nThe warm white light (2,700 Kelvin) is uniformly distributed almost omnidirectionally (300 degrees), and luminous flux with between 250 lumens (the 25 watt replacement) and 806 lumens (the 60 watt replacement) is as high as its specific historical archetype. Professional and end user variants are identical with this LED lamp type – the life of 15,000 hours and 100,000 switching cycles have been determined and ensured based on intensive quality testing. The period of warranty for both versions is two years and the color rendering index (CRI/Ra) is 80.\n\nEleven versions of the LED filament lamp from Osram have been available since October 1, in the classic shape as well as drop and candle forms. The 60 watt replacement lamps will be available from January. All LED filament versions have a clear glass bulb to emphasize their decorative aspect.
