Description:

Philips Ledino Nightwind garden lamp
Spruce up your garden with this minimal, but glamorous Philips Ledino pedestal lamp in first class aluminum and glass. The lamp creates impressive lighting effects at night. On the day exudes the powerful design force, beauty and simplicity.

Impressive, boldly and minimalist outdoor lighting from Philips. Ledino Outdoors elegant and modern style is the perfect method to beautify gardens, trails and outdoor spaces with light.

What can LED lamps of the discounters for 6 to 9 euros? Some amazingly much like the test of three “MeLiTec”-retrofits shows that there were at the beginning of the week as special offers at Aldi Nord.
13 variants were as from Monday on the shelves, all not dimmable with GU10, GU5. 3-, E14 or E27 socket, between 250 and 470 lumen luminous flux from 3.5 to 6.5 Watts and a “warm white” color temperature by nominally 2600 to 3000 Kelvin. During the led only with an average color rendering index RA > 80 were specified, should the round radiant models partly an excellent color fidelity of RA > 90 have – a rarity in such promotions.

At my request has my partner lighting laboratory three of cheap, non-dimmable Aldi-Nord – concernretrofits with EU eco-label A + and measured in detail before onward transport to me. I myself am one of the other half of the Split discounter in Germany(Aldi Süd) and have neither an Integrating sphere nor a device to measure the half value angle of LED lamps. So we must send every now and then back and forth test lamps, what good Holster not every circumstances – especially for robust handling of shipments by parcel service. More on this later.

LED Garden Lamp

The compact colour rendition of “Magic ball”

Officially 250 lumen to 2600 k, 3.5 Watt, 6 cm diameter, 9.5 cm in length, about 75 grams weight – quite unspectacular values for an E27-LED “ball”. Enough just as a replacement for a traditional 25-watt light bulb and take no more place in the light.
Then the gaze falls but on the value of color fidelity: “RA > 90”-which is much higher than what one would expect from a discount promotion for under 10 euros.There’s more than the EU minimum value for interior lighting from RA 80 rare (for comparison: incandescent and halogen lamps have about RA 100). The ‘ MeLiTec ‘ people did not invent but hopefully this number, or?

Commemorative half a second when you turn

Then let’s go with an intermediate practice test “Ecosavers”-energy cost measuring instrument. No real Malus starts the lamp with a roughly half-second delay – unusually for a non-dimmable model, but. Noise? NULL, no whirring or buzzing perceptible. I could not find even an flicker or flare. After two hours of “Swing a”, the meter shows 3.8 Watt electric power factor of 0.62 (in the Pro Lab there were 3.2 W and 0.53); the infrared thermometer registers uncritical 47 degrees in the hottest spot of the housing.
Nearly allés, what you need to know, has “MeLiTec” the box (left) and partly also on the lamp cover (right) printed – among others the nominal lifetime of 25,000 light hours and 20,000 cycles.
The light image (see the photo at the top of the post) by the light color and the angle produced quite light bulbs similar to appears. Subjectively, the brightness is located between a traditional 25 – and 40-Watt-“Pear”. There are probably a few lumens more than specified. Six SMD Chips in the base – are responsible for two “warm white” and four red (picture on the right).
You shine though with a half value angle 120 degree upwards; the light is however wider spread of the matte plastic cover and ultimately with about 230 degrees emitted (diagram of the light distribution curve).
Why “MeLiTec” got two different types of chip in his E27 lamp? Very clear: because the color fidelity. Most “warm white” LEDs on the market have still weaknesses in the reproduction of shades of red and pink current (as may 2014). This is particularly noticeable in practice such as the lighting of areas of the skin and certain foods (peppers, tomatoes), on paper at the reading for the single color “saturated red” (R9). Ideal would be 100; many LED lamps create here but only 5-25 (see also at “MeLiTec”, below).

Super value in the “red zone”

The discounter-of “Ball” is worlds better: the light laboratory certifies excellent R9 worth 81.6; also the “General color rendering index” (from eight unsaturated standard measuring colours) with RA 91.6 exceeds the factory default setting. However, the official, very “warm” color temperature of 2600 k is something in addition. In the laboratory, the light 2712 k was noticeably “cooler” (Pdf download of the test protocol).
The “color peak” is nevertheless abundantly clear in the “red zone”, such as the spectral graph displays (on the vertical axis the light power in milliwatts, on the horizontal light wavelength in nanometers):

And so it affects the image my default color fidelity model, a site Ducati 916 in miniature on a white background, “cloudy sky” photographed with white balance and without post processing:

The yellow-red shift of white and black tones is very clear, the reds seem alive and strong, shiny surfaces radiate “cute” – so we know also of tungsten filaments. That the LED retrofit illuminates the Motorrädchen also still slightly brighter than a 25-watt light bulb, has two reasons: the light is bundled something close toward the hood head and according to laboratory 284 lumens coming ‘ out instead of just 250.

Philips Ledino Nightwind Garden LED Lamp 1

My test result:

Already ordinary paper values of “MeLiTec” lamp are largely met or even exceeded, the price – to-performance ratio is exceptionally good. Unfortunately, failed once again on – and offline, some of the EU mandatory to name a few – for example, the color consistency in levels of SDCM. The spectral graph there was of course also the Aldi website, but only here in the blog.
With an efficiency of about 80 lumens/Watt and EU eco-label A + saves the compact E27-“Ball” opposite a 25 W light bulb electricity around 85% and is recommended particularly for colour-sensitive applications, where multiple copies provide sufficient brightness – such as Schminkspiegeln or in the luminaire’m dining table. There is the maximum for non-dimmable lamps of my LED rating scale :
four star.

The HV-spot as a 50-watt replacement

Just 6 euro for a PAR16/GU10 LED spot, with 300 lumen, 780 candela light and only 5 watts EU official can put a 50-Watt halogen lamps – that sounds but just fine. The “MeLiTec” model “L71″ differs however but somewhat by his power-guzzling ancestors: it is not dimmable, officially only a Farbwiedergabeindx of RA > 80 (instead of 100) and glows with nominally 3000 Kelvin slightly “cooler”.
The cast aluminium/plastic construction with silver fins, convection air hole, we know 5 cm maximum diameter, 5.6 cm in length and 53 grams of many similar models of other brands. And the appearance of the four LED chips under the cover lens/lens (pictured below left), for example, the spontaneously reminds of those, older OSRAM “LED superstar” which produce with 3000 K.

The “MeLiTec L71” spot starts anyway, without noticeable delay, remains pleasantly quiet and pulls 5.8 Watts with a power factor of 0.68 according to my amateur-meter. The lighting professionals from David Communication identified 5.22 W and 0.62.
The maximum housing temperature in continuous operation rose to 56 degrees. The light image (photo) shows two main-beam drumsticks: below a weak, relatively wide, a piece about a stronger, which is more tightly focussed, and therefore also quite far enough. The specified maximum brightness of 780 candela appears credible, but how does with light power and angle out?

Rating be achieved reasonably

The GU10 spot creates around 34 degrees half value angle and total 324 lumen (chart)according to the laboratory. For the par value, but only the luminous flux within a 90-degree angle must be specified when directional EU officially. We were once gracious and as a more realistic target for once everything in a 120 ° span accept: 292 lumen.
For the glaring lighting of my fidelity model it was up anyway, enough and the result a clearly different as with the E27-“Bullet”:

The white background remained neutral – with a lesser red cast; all other colors experienced a noticeable yellow shift, the really rich red tends to ochre. This is on the one hand due to the colour temperature measured by the laboratory of good 2920 Kelvin and the “color peak” in the yellow-orange range (601 nM), on the other hand on the moderate color rendering index RA 81.3 (Protocol).
The additional six measuring colors is noticeable especially the R9 weakness: only 8.6 at “Red saturated” is actually no longer the LED technology. Even though the appearance is superficially okay, I would not use this spot for the assessment of skin cosmetics, tanning levels, socks colors or vegetable maturity. There’s much more appropriate spotlights, which are however also (still) far more expensive.

My test result:

The nominal 5 watts strong GU10 spot by “MeLiTec” offers average quality at a reduced price. A year ago you would have to pay at least double for so a 50-Watt halogen lamps LED replacement. Nominal service life, efficiency and appearance go alright, can meet but no very high claims. From my LED scale, there are therefore only solid
three star.

376 0 lumen: the failure candidate

With broadband LED spotlights I had not much luck – the 5-Watt/GU5 this year. 3-“L45”-low voltage lamp of “MeLiTec” for 5,99 Euro (photos above: lamp and Pack snippet) nominally 120 degree half angle, 360 lumens, and 140 candela this series continues with unfortunately.
After the purchase of 42 gram of test light, light at Aldi Nord, the laboratory noted that it had loosened the connection between the noble-looking metal head and the plastic base. Inside the two screws in the plastic threads produced, which, however, were broken (picture top right). Thus opened up unwanted insights on the Board with the electronic ballast:

Was improvised to measure

For the measurements the two parts of the radiator was glued together makeshift – electronics and that was nothing until then obviously the twelve LED chips. In the sphere, they delivered a total 376 lumen luminous flux, slightly more than the face value of 360 lm. If a spotlight over 90 ° is half value angle, it is not “accent lighting” according to EU standard (spot) and the lumen rating must not be confined to splay. The light distribution curve was around 110 degrees (Diagram) – fits so.
The further transport to me got the lamp however is not good. The traces of a very robust treatment by the parcel to see were already outside the parcel, inside, apparently only two of the three models had suffered no damage. The GU5. 3 Spotlight anyway, no longer wanted to work with me – so there was initially no test and no illuminated pictures(see Update below).

Laboratory values must file this time

Remain only the laboratory measurements: 5.16 Watt (power factor can not be determined at low-voltage lamps, but depends solely on the Used transformer/drivers), colour temperature 2927 Kelvin, “color peak” 605 nM, color rendering index RA 84.2(Pdf download of the test protocol). The R9 value of 20.6 for the additional measuring color is somewhat remarkable “Red saturated”. This is significantly better than the above tested GU10 spot, and also the results of the other colors are higher. Here, so definitely completely different “medium power” Potter-LED chips, despite equal nominal color temperature.
What kind of 12-volt voltage the spotlight preference, unfortunately does not reveal the Pack. The plinth inscription suggests AC while using a wavy line; the lamp worked in the laboratory but a DC driver. “MeLiTec” told me to demand that the lamp should actually tolerate both without problems.
Update 3.6.: “MeLiTec” responded today to this post and want to send me several “L45” replacement copies so that I can complete the test. In contrast to the analysis, the defective heater goes ense.

Second attempt with the “spot”

Three new GU5. 3 Spotlight gave me “MeLiTec” – and what can I say: all three are undamaged and shine. So wrong with the test. Into the open socket and a “Govena”-Trafo launched the model without any significant delay, remained absolutely silent, moved two hours ‘Warm up’ net around 5.4 Watts (plus approx. 2.5 Watt for the transformer) and around 51 degrees on the hottest spot of the housing was warm; the glass cover reached 55 degrees in the “upcoming” operation. Up here no problem.
The gleaming, dazzling brightness at close range – thanks to the clear disc and high luminous flux performance was striking. Direct views of the spotlight should be avoided from the side. A Matt diffuser cover would be sure visually pleasant but also some of the beautiful lumen would swallow. Should you provide some at “MeLiTec” Variant – possibly in the form of a mounted by the customers attachment as accessories.
The light color similar to that of the above tested GU10 spot as expected, seems neutral, less yellowish, but just a tad bit further away from halogen and incandescent lamps. You see that maybe on my color fidelity standard image (“cloudy”, no post-processing white balance):
There’s more life in the red tones, a smaller yellow tinge in a really white background and the Black seat. Unpleasant blue – or green stitches are not noticed. You can expect much more from a 6 euro spotlight with nominal color rendering index RA 80 hardly currently. There are twice as expensive competing products, which make it no better.

About 10 mm longer than a halogen spot

Less beautiful: The total length 54 mm is much bigger than such as GU5. 3-LED spots of Philips, Toshiba or BenQ (approx. 48 mm) and low-voltage halogen lights (less than 44 mm). There are lights, in which the “MeLiTec” ll2 quite barely or not at all ‘ fit. If it goes well, he peeks out just a little bit about it case ‘ out. If it runs bad, can he front ceased to be secured in a ceiling fixture with parenthesis and dangles insecure around.
That happened to me with a round “night sky” by ‘ Paul Neuhaus ‘, in which I could unfortunately only test provisionally fix the three copies of L45. Even this fun but did not take long: the first day – after less than one NET lamp hour the standard built-in transformer, which had endured previous four years all possible halogen and LED lamps in the happy hunting grounds said goodbye. Why this all happened with the “MeLiTec”-Strahlern? No idea. Overloading can’t be it at a total of around 15 watts; the transformer is designed for four-time performance.

My test result:

There are not very often – low-voltage LED spotlights with a wider half value angle than 90 degrees, superior light quality and an overall brightness on the order of a 35-Watt halogen lamp even rarer for under $6. I’m glad that “MeLiTec” offers something – if also not dimmable. The optical appearance of the “L45” with visible wires and solder contacts under the clear cover seems to me although it needs improvement as the apparently break vulnerable fitting of the halves and the slight extra length. Otherwise there is nothing deserving of my LED rating scale but to complain about
three star.
Update 5.6.: The 60-Watt power supply of the lamp for the three GU5. 3-base was definitely cooked through – including the typical “Electronics stink”. Could be happened theoretically by a lightning strike with surge when the storm last night. Have it replaced by an LED driver and also with the help of double-sided tape choked the three “MeLiTec” irradiators in the versions. For the standard mounting brackets, no place was more front of course:
Lights everything just fine, without apparent brightness or color differences (I’m guessing times a SDCM value under 4). Customize approx. 3000 Kelvin “L45” my opinion also very nicely to the “neutral white” 4000-Kelvin mini LEDs around:
Still an improvement: the light hums no longer – as before with the series power supply.Let’s see how long this so works.
