LED lamps for mains operation or 12V connection, there are now some. The Lunartec 7x 3 Watt LED Spotlight ‘cool white’ PAR 30, E27, 230V is the first structure that provides common light intensities.
With the LED lamps from josephnightlights, it is not yet quite Cheating: effective, with high efficiency, they are, yes. But then it usually quite pale.
The reason: The power is low, a maximum of 3 to 6 watts even with almost 100 LEDs in the housing or a power chip. And 3 Watt Input with high efficiency and give up only a brightness corresponding to 12 to 16 Watt incandescent lamps, when happy times multiples is specified. Still clearly removed only by a 20-watt halogen lamp. The Lunartec 7x 3 Watt LED Spotlight “cool white”, available in Pearl, is the first time differently:
In him stuck not 12-90 normal white LEDs, but seven power chips, each with 3 watts. Makes a total 21 watts, which may correspond to an incandescent lamp of 60 to 100 watts – and that too with concentration of light!
Thus the Lunartec is 7×3 watts PAR 30 LED spotlight the first LED lamp that can really be competitive with incandescent lamps and energy saving lamps in the household. They are available in either cool white – similar to daylight, 1150 Lux slightly lighter – or warm white – with 820 Lux about 1/3 less bright, but rather fits in the light color to incandescent lamps.
Which color of light is preferred depends on the use case: How to work and lighting on overcast days the daylight color is better late at night would this one, however, make them awake. Then, however, could even the warm white version be overkill for their brightness.
As Photo lamps LEDs are not suitable, even if energy saving lamps because already celebrating success and LEDs to these significant advantages are: No slow brightening and no risk of breakage . But the spectrum of LEDs is still too unevenly – the tested cold white Lunartec 7×3 watts PAR 30 yielded compared to daylight a greenish image – and the light distribution as well: The LEDs provide a tightly collimated light with which can be only small objects photograph.
The crux of the Lunartec 7×3 watts PAR 30 is so far the price: They cost almost 80 euros individually, in packs of four still 250 Euro. It may well cost more some Designer lamp, but for a “pear” are one such sums hardly made, especially in the past some Lunartec lamps service life problems had.
But a price reduction only a matter of time – and by the light intensity the Lunartec 7×3 watts PAR 30 LED spotlight is now actually useful, what is not said of other LED lamps in PAR 30 floodlight form, but for normal LEDs, can.
