Review: Bioledex-Led Spotlights – More In It, As It Says

Four current Bioledex LED spotlight during my test and measurement laboratory have done surprisingly well. The brightness ratings were significantly exceeded;the light quality corresponded largely to the promised data.

Admitted: after various tests and experiences with previous Bioledex LED lamps (keyword: “corn cob”) I was initially skeptical as me “Home sphere”-online-shop free four white retrofit test models the “DEL-KO”trade mark from Augsburg, Germany wanted to make available. The Schwarzenbeker Engineer Ronald Wiggert assured me but that he had extensively tested the New Bioledex range and good.

Andindeed: I must pass by a few prejudices. Apparently, Bioledex has learned from the partly suboptimal results of the past and invested a lot to get happier customers and better test judgments. But will benefit the test Quartet, that these spotlights are generally not dimmable and hence No which often develop emerging characteristics with dimmable LED light sources : everything does not take place- and switch-off delay,WHIR, flickering or intense heat in the electronic ballast -.

The 6-Watt MIDI headlights

First candidate is the E14 – ll2 “Lifter” with nominal 6.5 Watt and 470 lumen luminous flux for 9.90 euros. As the two other E14/E27 lamps he has an beam angle of 120 degrees, so is because of the relatively wide beam (> 90°) rather than “Accent lighting”. Stated on the package, and therefore also the light (luminous flux per solid angle unit) officially only at 140 candela languishes.

In my open test version drew the spotlight in continuous operation according to my “energy meter” only approximately 6 W – electric power factorof 0.64 – and was warm at the hottest spot of the matte plastic hood maximum of 62 degrees. The white ceramic base remained significantly cooler and could be touched painlessly.

In the measuring laboratory then an unexpected: there provided the spotlight with 5.6 W just 516 lumen – 46 shone so lm brighter than specified (Download pdf of the full data sheet). So that he is more than just a traditional 40-watt incandescent spotlights replacecan. According to my calculation, reached the “lifters” an energy efficiency index (EEI) of just 0.13 this value and may therefore comfortably enthroned at level A + of the new EU eco-label.

All values in the acceptable range

The yield of fabled 92 Lumens/Watt is not bought with a significant loss of light quality.The temperature was in the laboratory with 2814 Kelvin in the acceptable range of the nominal value of 2700 K (“warm white”). The dominant colour is in the area of 584 nm wavelength (yellow-orange). You can see it pretty well when the light beam wild:

At the “General color rendering index” (R1-R8), almost a bull’s-eye (nominal RA 80) succeeded with RA 79.9. Significantly from the series, only the individual indexes for ‘Lilac purple’ (0,0) dance (54.4) and “Red saturated”. The latter no longer counts but asninth color to the RA average and already is considered particularly problematic for LED lamps. Bet that several older Bioledex lamps produce only negative values.

Passport problems should occur at 9 cm length, 5 cm maximum diameter and 71 grams in barely a lamp fixture. Life indicates Bioledex with 30,000 lights hours or 100,000 switching cycles and provides a three year warranty.

My test result:

Over 500 lumens from a “warm white” 6-Watt/E14-LED spotlights for under 10 euros are good arguments for the Bioledex “Lifters”. If you need a much broader cone of light as conventional halogen – or LED spots and no long range, then you can be perfectly happy with this lamp – for example, in the desk or night table lamp, as well as indirect background lighting. For the best rating for non-dimmable LED lamps (four star) lacks only a top color rendering index RA 90 or better. So there’s my scale after all
three and a half stars.

The 7.5-Watt spotlights Maxi

Almost everything that applies to the bright E14-“Lifters”, applies also on theBigger E27 brother for 12.20 euros with nominally 7.5 watts, 600 lumens, and 170 candela: beam angle, color temperature, color rendering, lifetime, warranty – all at the same level.

The measurements are with 2790 Kelvin and RA 80 in the frame of the LED usual scattering of series or exactly on point.The weaknesses in the individual colours “Lilac violet” and “Red saturated”(Download pdf of the measurement protocol) as well as the subjective perception of the light color and quality are also the same.

Of course, significant difference is the brightness. In the laboratory, the E27 lamp developed whopping 651 lumen – around 8% more than the face value, not much darker than a 60-watt incandescent spotlights.

Quite different power consumption measurements were: the professionals of determined slim 6.7 – my amateur devices strong 8.9 Watts. There was also at least one thing in common: both in the laboratory and with me the electric power factor was 0.54.

EEI 0.14 ranges “A +” label for it

If lm assume 7.5 Watts and the measured luminous flux 651 Bioledex par, the yield just under 87 lumens/Watt and energy efficiency index (EEI) is approximately 0.14. He is advertised on the packaging correctly rated “A +” in the new EU eco-label. In continuous operation in my open test version I’ve measured the infrared thermometer at the hottest point of the matte plastic cover maximum of 55 degrees.

There are no surprises at the light frame also: as the E14 Spotlight also this E27 lamp in many cases can serve as a “half-round” light source.

The dimensions are absolutely suitable to retrofit: 106 mm length, up to 63 mm diameter, 122 gram. Negatively noticed me however is the slightly negligent closely consulting of ceramic cooling fins. Here you can scrape out white particles from the wells – some crumble may also itself off. Technically, it has no meaning, optics aesthetes may feel that perhaps as a deficiency.

My test result:

Over 650 lumen light output from about 7.5 Watts with a beam angle of 120 degrees can be a serious alternative for supposedly “round brilliant” 60 watts/E27 light bulbs LED replacement with 10 Watts or more partial. The Bioledex-“Roder” ll2 is especially comes into its own when you need the light only in the range between a third and a half of a full circle – about the dining or desk. 12.20 euros although no predatory pricing for a non-dimmable LED bulb, but justified by the special shape, the retrofit capability andefficiency. Therefore, there is also here of my LED ratings
three and a half stars.

The super light GU10 spot

“Helso” is called the official 6 Watt strong, non-dimmable GU10 spotlight by Bioledex for 15,80 euros, who was unfortunately still a stale packaging with partly wrong information on the way. As the former EU eco-label by G emblazoned there until A – of course, the “Helso” there has the best rating (picture below).

Also what does it by 65 mm total length;that would be a good deal above the class average. Indeed, it is but the specification of 50 mm for the maximum diameter is correct only about 58 mm. however. Also I prepare no problems measured 57 grams of weight, if you want to replace traditional 50-Watt halogen lamps.

Like now? 6 LED Watt to deliver aboutthe same brightness as earlier 50 watt?Yes, they do, even if the Pack reveals the whole truth. Although already nominal 450 lumen would be sufficient luminous flux and 750 candela luminous intensity at an angle of 38 degrees loose as EU-compliant PAR16/50W-Ersatz. Actually, the part in the laboratory but enormous 515 lumen haute ‘ out (Pdf download of the test protocol) – such magnitude look long at the decent GU10 LED spots.

Then was probably the power consumption, the light color or color fidelity cheated, or? Nope, everything in the frame: 5.5 Watts at a power factor of 0.56 in the laboratory, 6.4 Watt and factor 0.67 at me. Proper color temperature: 2777 Kelvin (nominal 2800 K). General color rendering index RA 81.3 (nominal RA 82).

“Hautfreundlicheres” light

Interestingly, the weaknesses in some colours are not as pronounced as at the E14/E27 spotlights the Bioledex GU10 spot: after all, just under 60 “Lilac violet” and 13 at “Red saturated”. Also subjective, the light appears “skin-friendly” than the other test candidates.

A look at the appearance of the “Helso”(picture on the right) reveals the cause for this Abstrahlcharakeristik: a hexagonal led lights up in the middle of “Array”, all around is a reflection of structure, in a combination of lens and lens.

Looking for cooling fins or a passive convection cooling in vain at the white plastic cover or ceramic base. There is no thermal problems yet: after two hours in the open test version I have measured up to approx. 60 ° c at the hottest point of the case.

The life of information corresponds to the other test models: 30,000 hours of light, 100,000 switching cycles, three years warranty. The actual efficiency is less than 86 lumens/Watt, the energy efficiency index (EEI) for my Bill and the laboratory measurements at just over 0.13.

It scars the spot only by a whisker at the top classification A++ for directional passing and should adorn themselves on the next versions of the Pack pride with A +. Then you should customize also the officially specified Stromsparpotenzial : instead of only 80’s are actually up to 88 per cent – that not bad really.

My test result:

€16 for a non-dimmable GU10 LED spot sounds first exaggerated. If you but bear in mind that these small emitters can generate as much overall brightness as the much larger E14/6,5W-“Lifters”, more light intensity due to the narrower beam angle even to length and range creates, this still quite comfortable and really “warm white” lights up – then puts into perspective the price. Okay, the colour reproduction is not top class with around RA 82, but there’s a bonus of efficiency and therefore the maximum rating for non-dimmable LED lamps from me by
four stars.

The 3-Watt mini heater

Very little space in your lamp with E14 Sockets? Usual brand LED-“Drop” and ll2 there do not fit ‘ pure? Then this could be the solution: the official 3 watt strong Bioledex “Roder” costs 8,50 euro, is only 68 mm long, has maximum diameter of 39 mm and weighs just 33 grams.

For all other data – except for the brightness – is about what you have read with the stronger Bioledex spotlights -, for example, the missing dimming, the “warm white” color temperature by nominally 2700 Kelvin, the wide 120 degree beam angle or the 30,000 hours of light…

Snoring… No, I will not bore you. Because now, you have endured so long in this miserable long Quad test, because you expect a laboratory test surprise yet again, gell? Get.

Almost 25% brighter than indicated

230 lumen luminous flux have been officially, measured but were about 285 lm – almost 25% more! Loosely equivalent to the brightness of an 25-watt incandescent equivalent. While the mini spotlights in the laboratory moved 3 watt electric power factor of 0.38 exactly (with me it was 3.8 W and factor 0.42). For the color temperature with 2840 Kelvin was ‘coolness’ somewhat as the nominal value. Any deviation in the color rendering index: Ra 80.2 – with similar values as in the other E14/E27 lamps (Pdf download of the test protocol).

Starting from the laboratory results we would have a yield of 95 lumens/Watt and an energy efficiency index (EEI) of less than about 0.10. And that’s good enough for the new EU eco-label for bulbs not only for the officially advertised level A +, but even just for the best A++ class!

Even in continuous operation pretty “cool”

If has to do it with this enormous efficiency or with ceramic base, coming the mini “Roder” without fins and slots? Even after several hours in the open version of the test, I’ve measured in any case not more than 46 degrees at the hottest point of the housing. It is likely while in a partly closed luminaire more, but should nevertheless remain in the critical area.

My test result:

Hard to believe, what to a dwarf on brightness ‘ comes out. With this 3-watt Bioledex-“Lifters”, you could convince even die-hard skeptics who still believe that LED lamps are too big, too heavy or too dark. 8.50 euro are although not a bargain price, but you get a Stromsparpotenzial of almost 90% over traditional incandescent and halogen lamps – without too heavy loss of light quality. What can otherwise be of my LED rating scale as

three and a half stars?

Applies to all presented here spotlights and the rest of the range: the “Home sphere”-online-shop can the parts on request (up to three different articles to an order volume of 100 euro) test up to two months. Within this time you get the money back in return (you must pay shipping but even). Otherwise, legal, free return policy applies in the first two weeks. Mostly already enough to make a first ruling.

Update 10/31: After this test, “Home sphere” has lowered the prices for some models: the E14 “Roder” ll2 costs there currently only 9,40 (6.5 W) or 7.49 euros (3 W); the E27 version 7.5 w is offered to 11.85 euros (each plus shipping).
