Now there’s a well-priced, efficient and compact Philips LED light the traditional 60-watt-“light bulbs” to – replace with only 7 Watt a challenge to the cheap competition. The test with laboratory values but reveals that these non-dimmable E27 retrofit has some weaknesses in the color reproduction as well as the Declaration of their brightness and mass.
Slim 3,99 Euro this non-dimmable Philips LED bulb cost late last week in many “Kaufland” book; their MSRP is 5.99 Euro: with only 7 watts, the Nameless E27 retrofitto with “warm white” color temperature 2700 Kelvin produce 806 lumen luminous fluxand be so a particularly cheap and energy-efficient successor of 60-watt incandescent.
External form and presentation take the synthesis of artificial light classical and fashionable – with the slogan “it of classic – it’s LED!” on a traditional cardboard packaging and a slightly Matt, drawn up almost down to the base glass hood in pear shape, of this only by a white Alugussring separated. A real case there’s no Philips models as for other :
The components of the electronic of ballast largely down to be hidden in the silver screw base and are only partially from above through a narrow, clear part of the hood to see:
That is likely mild agree even the most die-hard ‘ light bulbs ‘ fans, which is shaming for years partly chunky, ugly housing or offensive ‘high tech’-Anmutungen E27 LED bulbs.Still hot for them it was of course, even if everything else as would be used – for example the size. And here the package information give already the first shock absorber (see photo montage, below) and the online datasheet : total 110 mm long and up to 61 or 60 mm thick it should be the new Philipsretrofit. Real – so fat?
For comparison, a 60-watt incandescent light bulb has only approx. 95 x 55 mm and weighs about 26 grams. But anyone who puts Grandma and granddaughter directly next to each other in the hands, immediately realizes: sooo vary in size and weight are the two do not. And actually revealed the new Philips LED lamp tolerable 105 x 57 mm and only 43 grams weight my rough measurement – it compact for the most housing and easy enough. Whether the “pear” has shrunk somewhat on their way from the production country Poland to us and product management in the Netherlands’s not overheard in a hurry of the launch?
The extended operation brightness is flutes
A declaration issue: the luminous flux. Although the lamp was especially right after turn on pretty “cool” and bright, reminded me of very light colours of the recently tested 8-Watt OSRAM-“LED Star classic A 60”, but shone after prolonged operation somehow different than before. Objectively assess a highly suggestible and less accurate human Visual apparatus can not however – there already the Pro Lab of my cooperation partner’ David communication ‘ must ‘ ran. Here, the lamp in the cold state delivered yet 784 lumens, which however does not matter for my standard test procedure.
Because here counts only the light after two hours endurance… and then there were only 728 lumen, almost 10% less than the promised 806 lm (Pdf download of the test protocol). After all, the power consumption (6.7 watts), the electric power factor (approx. 0.60), the colour temperature (2646 Kelvin) and the “General color rendering index”measuring eight-color (RA 81.8) remained largely at the level of the factory specifications.
With ACH and crash in A++
The past warm Philips LED lamp creates with an energy efficiency rating of 0.11 just yet so the advertised best EU eco label A++ (Pack snippet links). It seems this luminous flux loss to have nothing to do with a significant heat.
In my test version that is open, hanging the lamp had maximum 48 degrees in the hottest spot after two hours up at the base. In the upcoming operation, there were only 39 degrees up on the hood. One might almost suspect that inside a cooling gas circulates – similar to how at led “Fadenlampen”.
24 LEDs provide quiet, flicker-free light
I’ve heard whirring noise at any time; the delay was pretty short with less than half a second and the camera display nor the “Flicker Tester” app “Viso systems” (screenshot on the right) registered an appreciable flicker. Index of 0.0 and a rate of only 3% at a reference frequency of 100 Hertz are very good and cannot be perceived even from flicker-sensitive people.
If something interferes with the subjective impression of light, it is the highly visible arrangement of LED chips under the hood part transparent. There, around eight vertical rows with three SMD Chips, which offer mainly much side light stick to a central “turrets”. This principle resembles some older “Segula” models, partly also to the first “Cree”-retrofits with their “filament Tower”. You see the effects on the photo top in the post, here in my standard light picture…
… and my partner laboratories, radiation diagram the a this kidney shape with strong bays up and down shows (Download pdf). Traditional light bulbs emit much rounder and smoother.
Yet Philips stating “300 degrees” does not belong to the defects of the Declaration: the half-value angle is even good 309 degrees in truth and is therefore at the high level of the trendy”Filament”-LED lamps. The view from the top (photo left) shows the partial shading the shortcoming but towards the top of the hood.
Colour rendition looks better than the lab values
How laboratory measurements on wrong track can do, also the assessment shows thecolor fidelity. For the Philips on paper at the particularly difficult for LED lamps values partly not good looks: skinny 55.6 for “Lilac violet” (R8), only 76.6 at “Blue saturated” (R12) and very weak 6.4 for “Red saturated” (R9). The complete color rendering index of 14 measuring colors is below-average 77.1. Also the color tip of the spectral diagramis scarce 609 nm wavelength still in a pretty bright orange range – in direction, red does little.
It actually promises nothing good for my default color fidelity motif with a site and a deep blue motorcycle in miniature against a white background (white balance “daylight”, without post processing). And yet manage Philips once again to make the feat, the reflected light of a RA-80-LED light bulb for more:
Of course, that clearly is not the product of a Ra-90-lamp, especially not at the Ducati left, looks amazingly balanced but for a “warm white” light colour and neutral. The usual Ochre-yellow shift is not exaggerated, even the dark blue remains still as such recognizable. Maybe a hardcore light bulbs pendant is even too “cool” the Philips light.
Mostly, this impression only through the direct view on an LED lamp – particularly when this model comes with its not really dull cover. Who judged but only the effect in the room and lit objects, perceives the semiconductor light as much “warmer”.
Is still a main argument for the conversion to LED lighting: the longer shelf life. Here you must however make strong smears at the new Philips lamp: only 10,000 light hours and 20,000 rated life cycles as well as no warranty period deviating from the legal warranty show that calls for a cheaper shopping partly a certain modesty in the entitlement attitude of patronage. The new offered in the same segment OSRAM “LED Star classic A 60” promises but at least 15,000 hours, 100,000 cycles and three year manufacturer’s warranty.
My test result:
Who is for around or under $5 no Wonderland promises, could the New Philips LED lamp operated quite well be(the image at right shows the back of the cardboard packaging). Dimmability, top colour reproduction, a part of the promised brightness, a really round and uniform radiation as well as long life time or warranty missing here though.
This E27-retrofit is significantly more compact than specified (the cuckoo know why Philips on the packaging and in the data sheet not correct ‘ can take over), their role model is externally very close and provides a perfectly acceptable light color and quality.Buzzing, flickering, or long thinking time when you turn are foreign to you.
With less than 7 Watt power consumption and a measured by us, excellent hot operatingefficiency of almost 109 lumens/Watt energy-efficient replacement for 60-watt incandescent is the retro designed Philips in many, not particularly demanding everyday applications as enormous. On my five, strict LED rating scale that is a clear case for
