The intense summer heat often prevents us to carry out our activities in the interior as we would at another station. That almost suffocating feeling can be decreased with the use of LED lamps.
A change in home lighting can make a big difference. Traditional lights generate heat in the atmosphere, while the LED does not.
Incandescent lamps only use 5% of the electricity consumed in illuminating, while the remaining 95% escapes in the form of heat energy.
Light colors on walls and ceilings can also help reduce the effect and energy consumption, since they reflect the natural light and absorb less heat than dark tones.
Also keep in mind that it is necessary to analyse how much lighting requires each area of the House. More illuminating a place with another type of light sources can make it especially hot, in addition to subtract interest to its content.
Another important point is balance the artificial lighting with the natural in each space. Leaving only support the first, you will save energy and will get much more welcoming environments. A site with many entries of natural light which in addition to too many lamps may become distractor and little comfortable.
Make your house comfortable and safe with LED, while you save money and protect the planet.
Light range from few Watts: OSRAM offers with its new “LED Superstar PAR 16 advanced”series. Thanks to a narrow beam angle of 25 degrees, the GU 10 spots partially create the light intensity from conventional 50-Watt halogen lamps – at one-tenth the power consumption. In the out site– test: the “warm white”, dimmable 5-Watt spot.
Replacement of power-guzzling halogen spotlights Meanwhile among the problem loses ten tasks during the conversion to LED lighting. Many manufacturers offer a wide range of various PAR 16 advertisements – with all possible beam angles,temperatures, and luminous flux; Many also easily dimmable GU 10-high-voltage or GU5. 3-low-voltage spotlights.
For pretty much every application, however, you will find the appropriate, with gradually high-quality brand-LED lamps at affordable price regions.
About 20 euro you must create ‘made in China’, for example, for the new dimmable OSRAM GU 10 spots – with 4 or 5 Watt power consumption, either with “warm” (2700 Kelvin) or “neutral white” color temperature (4000 K).The latter are about Office, kitchen, staircase and bathroom, the other more for the living room.
I have a “warm white” spot called “LED superstar PAR 16 50 25° advanced” made (picture left before unpacking). Predecessor strong compared with a 5.5 Watt optical as well as technical differences stand out. The newcomer is no longer white, but dark grey and has no inward-pointing level in the lamp head:
Just cut spotlights it now quite possible that the head protrudes a few millimeters above the housing – no big deal, but striking:
Because in my case the new lamp color stands out much less of the case than the previous white, you can sell the desired design feature also. A combination of“Superstar old” and “new” next to each other is however. You will notice differences also switched on. This begins with the warmer color temperature (2700 instead of 3000 Kelvin) and the slightly larger overall brightness (220 instead of 200 lumen luminous flux) and continues with the light beam.
Only my older “Superstar”spot has officially 35 degree beam angle, the new 25 – the effects are nominally on the range or intensity of (600 versus 900 can dela) and on the “belly” of the light cone.
The upper (new) OSRAM – spot lights something narrower, but further than the bottom, old. The different colour temperatures of the spots mix here to a large extent.
The closer look on the one illuminating lamps is noticeable but still an interesting detail.Apparently the newly designed lenses/lens attachment makes sure that the light slightly wider and smoother is spread directly after leaving the lamp head than the previous model (image right, viewed from below). Here, there was a clearly curved (here vertical) light output line:
However, the beginning of the light image at the new acts “LED superstar”series almost drawn with a ruler:
Other beams of light were sure easy to realize with appropriate optical inserts. In the Interior of the spots – (false, see comments) Midpower – SMD LEDs with approximately 120 degree beam angle – “Chip on board”light on the top Board three surrounded by various resistors, capacitors and a rectifier diode:
The rest of the electronic of ballast is located in the base – normally invisible–including:
These devices also ensure that the new spot with many conventional dimmers can be regulated. In my tests with four different models of dimmer (three of them theoretically unsuitable) there was no flickering, at most a slight whirring in the dimmer or the lamp.There were the older models some more problems. Improved the dimming is also another feature: in the lowest level of my Legrand-Dimmers, which I had adjusted for the previous spots, which remains completely dark new “Superstar”. A little higher shot which looks in comparison:
The new model left turns with less than 10% of the maximum brightness while the older is already about three times as bright. For owners of non-adjustable dimmers, this means that the new OSRAM spots can be dealt with darker than the old. They still mostly with full force – which is thus better to influence over the entire path of the dimmer brightness and the range light wider at maximum setting.
Bought is this progress with a light on and off-delay – a well-known phenomenon in high-quality, dimmable LED light sources. As a development engineer told me, control circuits (ICs) if used in the ballast of modern LED lamps, working largely digital. This allowed – in contrast of to older, mixed digital/analog ICs – a much better Dimmability, need some startup time, but to determine whether a dimmer is connected and on what level it is. Usually that works in less than half a second.
Seen from a different perspective, are the different light colours of the two generations of spot clear – because of the camera digital technology but less at the light source, but more on the ceiling reflection:
You can see: red links is higher than in the previous model law. The new spot is therefore “warmer” and “home” – very close to the conventional halogen spots. The other way around, it is the “tangible” Celsius temperatures. In the continuous full load operation I maximum around 45 degrees measured on the new lamp head, about 5 degrees less than that of its predecessor somewhat power hungry. This is of course due to higher energy efficiency: nominal 44 instead of 36.5 lumens/Watt.
No news there is the color rendering index: Who is still around RA 80 – While this is not top quality, but okay. The lifetime is specified by OSRAM with 25,000 hours of light and at least 100,000 switching cycles the factory warranty is four years.
My conclusion: The new 5 Watt OSRAM spot has by far not a 50-watt high-voltage halogen lamp luminous flux (over 500 lm) course 220 lumens. He can replace but still anywhere because of the narrow beam angle of 25 degrees and the associated high luminous intensity of 900 can dela, where heavily bundled and far-reaching accent lighting is needed.
Despite the possible energy savings of up to 90%, you have to accept any noticeable concessions in light quality and dimming. The high price of Around 21 Euro relativized by the roughly 25 times lifetime compared to a halogen spot.
Since I can barely different to grab as handfuls in the pile of my LED rating scale and the maximum possible five star ‘ to get out.
