Dimmable Globe LED Lamp Review

A new dimmable and very color-accurate globe LED lamp of the Austrian premium provider LEDON is 18.5 cm long and up to 12 cm wide. From less than 13 Watts, offers the G120 according to laboratory measurement approximately 1200 lumen and lights to something brighter and more efficient than specified.How it looks with the other qualities of the E27 giant retrofit and why LEDON now simpler packaging used here is my detailed test report.

Dimmable Globe LED Lamp Review

Before approximately one year LEDON joined the “climate neutrality Alliance 2025” – with the aim to make the ‘carbon footprint’ of the Vorarlberger mid to zero. Actually obvious if one is already energy-saving, environmentally friendly lighting. For example, the flowing transition of packaging is one of the many steps along the way.

Instead of complex hybrids of thin high-gloss cardboard and clear plastic viewing windows are the dimmable LED lamp by LEDON and lighting fixtures are now in a plain, brown and rather thick cardboard delivered. The yellow-colored tops are single concession to the old hull design.

Packing size of a Hi-Fi box

This of course also applies to the largest LEDON-retrofits, whose new packaging about the size of a large shelf speaker (pictured below left). The most prominent is a color code Strip, indicating companies typical, for example, the dimming of a light (red) along with a schematic illustration of the product, the new slogan “pioneering light” and the lumen. You can see bottom right of 229 grams heavy package contents in the case of the current, officially around 25 Euro expensive test specimen is how cozy, size compared with a 1.5 volt AA battery (Mignon).

At least the housing base with LEDON normal wave pattern (“wave design”) might seem familiar to you. It is outwardly the same cast aluminum design like the normal-sized E27 / A66-“Pears” the Austrian. And also under the matte plastic hoods – where the LED chips, lighting – there should be probably no major technical differences between the A – and G sister models. The same current ratings close to (lower left on the packaging top of the G120) place at least.

The note printed on a side of the package “Made by Austria” (pictured above right) you may way, not as “made in Austria” to interpret. Actually a large part of the production in China is completed – of course under Lustenauer Director and quality control. That must also ensure compliance with the performance standards in the production.

Let’s see if this works: in my open, hanging test version and a normal switch which emits nominally 12.5 watts strong G120 globe LED lamp after less than half a second full light to a minimal purr that is audible in quiet environment up to maximum 5 cm distance. After two hours continuous running my amateur meter shows 12.8 W power consumption using a electric power factor of 0.81 (Pro Lab: 12.9 W, PF 0.82 – so almost identical). At the hottest spot – top on the base – the IR temperature sensors reported acceptable 77 degrees 25° down on the hood were only about.

The light is as good as flicker-free

Very good news there was at that time by the Flicker-front: 0.0 and only 4% rate showed my “Flicker Tester” app at a reference frequency of 100 Hertz index – was also in operation with all dimmer models and their measurable brightness settings (in very low light, the app provides no values).

My blog partners “David communication” identified with the Professional device “FM ch” maximum 6% dizzyingly high 73 kilohertz – flicker rate far beyond any threshold of perception. LEDON himself is less than 3% at frequencies to 165 Hertz. Also very flicker-sensitive people should be aware of so the LEDON globe led a stable light source.

Wide-field, “warm” and homogeneous light source

Subjectively, the G120 acts the EU official equivalent a clear 75 watt bulb relatively ‘warm’ and not as blindingly bright as you would expect’s color temperature and 1050 lumen luminous flux of a LED lamp with 2700 Kelvin – after all. That is partly the large, Matt hood, which broadly and uniformly scatters the light as the light image shows:

Amazing that the dispersion diagram from the laboratory with 250,6 degree (Download pdf) not quite confirmed the official half value angle of 270 °. -Over 10% more than promised also notable: Instead of 1050 the Integrating sphere gained lumen whopping 1185. The measured efficiency of less than 92 lumens/Watt was thus than in the LEDON datasheet called luminous efficacy of 84 lm/W. The lamp is so the EU eco-label A + rightly (print bottom left).

Yet the proper color temperature was significantly “warmer” than indicated, although costs usually efficiency: 2607 instead of 2700 Kelvin, objectively confirming my subjective impression.

The chromaticity coordinates of the giant globe lands (diagram right)slightly above the ideal of “black body curve”. A similar result was also already in the test of the smaller A66-“Double Click” nurse.

Color fidelity is sufficient not only for mopeds

The same applies to the perceived and measured color reproduction of the G120 on almost identical, high level operates. Here for the first time, my default color fidelity motif with two model bikes against a white background – photographed white balance “Daylight” with no post processing:

Especially when the site Ducati, the LEDON plays their strengths; the deep blue Yamaha suffers somewhat below the Orange shift usual even in incandescent, however, by their very nature. The “General color rendering index” is at RA 91.7 – with very good values for the additional measurement colors “Red saturated” (57.2 = R9) and “Skin color pink” (R13 = 92.4).

It would speak for example, nothing against use in upmarket restaurants or hotels, where such Globes even on ceiling or walls directly in E27 fitting versions could be screwed (don’t forget sufficient rear ventilation!). So, the complete light bulbs would mutate without having yet zusätzlicherer housing or “Lampshades” may be required.

The nominal lifetime of 25,000 hours of lights and 100,000 switching cycles, as well as the five-year manufacturer’s warranty are already at the level of very good Integrated LED lights. Thus, even the relatively high price of Around 25 euros would be justified, especially since you can safely use a certain margin for negotiation as a commercial customer in larger quantities.

Smooth, flicker-free dimmer control

It is still some sensitive subject of dimmer. Most is running trials with a non-adjustable “be” phase dimmers. Here, there was a steady, flicker-free brightness across the entire dimmer path between 3.6 and 14.5 watts total power consumption. It was about a range of 15% to 100% of the maximum luminous flux. The delay prolonged at low setting on little more than half a second; the whirring noise was a little louder and up to 20 cm distance can be heard – all still in acceptable limits.

For the adjustable young phase control dimmers it mattered very, not too low to adjust the lower threshold on the screw. Otherwise it could take up to two seconds, until the globe after switching from ‘very dark’ (for one second) over “colored” fixed gradually on the selected level and then clearly visible flickered. Flicker-free and fairly evenly worked the scheme between 1.4 and 13.9 watts total output respectively around 10 and 100% brightness.

On the phase control dimmers it louder is

Especially at a medium setting, dimmers and light buzzed but vocally in the Duet – a distance of partly about a half meter. Definitely not for children – or bedroom. As so often, I recommend a adjustable phase dimmers for this LED retrofit with a minimum load of no more than 20 Watts (when using a lamp only).

If you operate multiple lamps of this performance class in the same dimmer circuit, also a not adjustable dimmers will work well, because then the length of the rule is usually automatically expands down and covers a very wide range of “Almost dark” to “full speed” in the best case. The official dimmer test list by LEDON (Download pdf) anyway, is a valuable aid in your selection.

My test result:

The dimmable, officially 12.5 watts strong/E27 / G120 globe LED lamps actually met the premium claim by LEDON (and I say this not in any lamp from Lustenau): material processing quality, nominal durability and warranty, flicker-free light with high color fidelity, brighter and more efficient than promised – slight variations in power consumption, color temperature, and half value angle, which, however, have a really negative impact.

That the controllability with different typical household dimmers can be subject to various restrictions, applies to Nearly all LED lamps and can get themselves only with very elaborate technical detours in the handle. Officially nearly 25 euros are already a proud price daily crying duration of use after long to achieve a rapid return on investment through the approximately 85 percent power savings over a similar bright light bulb.

My strict, five LED rating scale can not the excellent top grade pay for for this though, but still very good four star.
