Over 1500 lumens, “warm white”, largely around radiant and even dimmable: the 20 Watt powerful Philips LED retrofit bulb is “master LED bulb MV” since mid-2013 the most powerful A67 – on the German market, but also one of the most expensive. Can she justify their high price?
“Philips Lighting” offers worldwide currently several concepts at his round radiant LED Retrofits for the traditional E26/E27 screw versions: the idiosyncratic‘ SlimStyle’ shape with the look of a mini-softball bat; the Compact “light bulbs” design that is as closely aligned with the usual lamp silhouettes; the fungal“hue”approach with a long body and relatively short hood (here a model in the blog test) and the “remote phosphor ‘principle as in this test lamp.
Here Potter no blue LED chips with directly mounted yellow Luminiszenzkonversions coating under a dull or clear hood, as with the other three concepts and the most “White” LED lights on the market. Instead, a variety of SMD LEDs may light inside around completely uncoated. Alone who are away for their “Royal Blue” light through additive color mixing white conversion (Engl.: “remote”) mounted yellow outer shells responsible.
Very flexible Cup concept
This principle guarantees no better light quality or greater brightness in itself, but it has its advantages: uncoated LED chips have less thermal and chemical problems. In the further development of the conversion technology, they can remain unchanged in the successor models because the manufacturer must install new outer shells. Theoretically, modifications of the color temperature of “warm” and “cold white” are possible so very easy.
Some experts say also efficiency benefits of this concept; If you listen to but mainly from the ranks of the LED conversion shell provider and could be therefore somewhat optimistically calculated. The “master LEDbulb MV”test lamp is ‘made in China’ from the‘Professional’Department of Philips anyway, 76 lumens/Watt, an energy efficiency index (EEI) of 0.18 and level A in the new EU eco-label not exceptionally implementing strong.
Brighter than a 100-watt incandescent
For this she shines as only E27/A67-“Bulb” of the great brands on the German market with the EU compliant equivalence to a traditional 100-watt-“light bulb”:
1521 lumen LED light power exceed even the yield of their power-guzzling ancestors(just under 1400 lm); the nominal lifetime of 25,000 hours of lighting and 50,000 switching cycles is higher anyway many times.
Play in another League the mass: less than 13 cm in length, maximum 6.1 cm wide and 224 grams – so a stable built “Monster” certainly does not fit in all household lamps. If necessary the “warm white” color temperature of 2700 Kelvin is pretty identical (Pdf-download English data sheet).
Pretty unobtrusive desk
In my open test version was the Philips LED flagship first on a normal switch light(pictured left). It did without noticeable delay, however with a slight whirring, that distance was silent environment up to about 5 cm. After two hours of “warming up” was this noise still quieter, and mean“energy meter” showed a power consumption of 19.8 Watts at an idealelectric power factor of 1.0.
Where exactly are you in this lifetime measure the highest temperature, depends on the installation position: at the Assembly there were maximum 70 degrees on the hood and 60 ° on the cast aluminium housing with his fins. Hanging these values have reversed course, because heat rises as you know. Locations recommended only Open/ventilated lamp – with a temperature range of environment between-20 and + 45 degrees and maximum 80% relative humidity.
On the first dimmer of significantly louder is
Philips promotes its “master LED bulbs” among other things with the carton and label“high performance dimming”, what I understand as a call to the especially critical check regularly. Somewhat reluctantly the lamp in one not acted adjustable Phasenabcutting dimmer. Delay typical of many modern, dimmable LED illuminant partly increased by over half a second; the buzz was something loud and noticeable depending on the dimmer position 10 to 20 cm away.
The brightness changed at the bottom of the rule very quickly in the upper clearly sensitive, but always flicker free. The power consumption could be varied between 3.7 and 20.8 Watts with a maximum power factor of 0.84 (manufacturer: 0.7). Here, the light color seemed to change: stark dimmed – 250 lumens – little green-tinged, ungedimmt with a penchant for pink.
Amazing wacker on the cheap dimmer
Cheap DIY phases on was also for test operation on an actually inappropriate, cut dimmer. He took the lamp however partially to significantly sincere 100 Hertz hum. In darkest dimmer position (4.4 watts) I could perceive distance that despite Presbycusis in around one meter. This distance was reduced gradually to acceptable 5 cm to the brightest level (20.2 Watt, 0.75 power factor).
On the other hand, this usually little recommended combination with an ordinary reaction speed impressed (< 0.5 seconds delay) and a flicker-free, largely uniform change in brightness over the entire range. Without additional adjustment screw on the dimmer you can download rules but to forget to complete darkness – works in most cases not in LED lamps, no matter, whether with phase or phase dimmer.
All around nothing in the dark remains
And what about now ungedimmt the light of the “master LEDbulb MV” ? Insanely bright, is therefore also something “cooler” as felt between 2800 and 2900 Kelvin. The light distribution is pretty even – apart from the slight shadows through the three thick legs in the hood, which hardly fall on long distance or in a dull housing. Philips called the packaging “light all around” – can you leave so.
However, the official “General color rendering index” is only RA > 80, what can be expected no sharp quality of light. After all, creates an ancient “lightbulb” RA 100; even some “Ledare” lamp from IKEA Frolics Meanwhile naughty in the RA-90 range. Actually, I’ve seen already far more compelling representations of my standard color fidelity motif – a red Ducati 916 in miniature against a white background:
The recorded as always with white balance “cloudy” and uncorrected photo shows significant color shifts. Mix in the white and black green -, yellow – and pink; the really rich, deep red of painting tends towards bright red or ochre. This rendition is certainly far from the optimum, with blue LED light and “remote phosphor ‘dishes could be achieved.
More color fidelity should be only a matter of time and/or money probably also with this concept though the Philips lamp with about 40 EUR street price in the luxury League plays. However, it has almost a unique position as a 100-Watt replacement and can save around 80% compared to the slightly less bright incandescent power.
My test result:
Also at this expensive LED bulb is much air above. Not in the enormous maximum brightness – you need that probably only to relatively few locations and lighting situations. Dimmer tolerance, light color and color fidelity are but only average in the current market environment. If you are ready to lie for now still a rich two-digit euro sum, is a very individual and not necessarily rational decision. Would finally be possible that come 2014 better for less money in the market.
“Power saving” is probably not the only reason, but certainly also the certainty and the pride to have something “Special” – like die-hard fans who decide when purchasing a car never for the cheap base model, but always for the Sau-expensive top version in many cases. As I also belong to this “Aficionados”, I buy you the 20-Watt Philips-benevolent“master LED bulb MV” of my reaching up to five LED rating scale
Update 22.01: Today came the laboratory values of the test lamp (Download pdf of the measurement protocol). Certify excellent 1663 lumen luminous flux 19.6 Watt andpower factor of 0.92. a color temperature of 2658 Kelvin and a color rendering index RA 81.6.
As suspected by me in the test, the appearance of red (additional color R9) with 30.8 and blue (R12) with 56.7 is only average. The spectral diagram shows the color tip at 618 nanometer wavelength and the dominant color impression at 585 nm – there’s a noticeable amount of Green:
