Stiftung Warentest: Lamps tested in 2015
Stiftung Warentest calls 30 lamps for a big test: Which LED lamp really contains a large lamp and which one also saves your wallet? Only one lamp got a "very good" and is quite cheap. We show the tops and flops from the test and give tips for buying lamps.
Product test winner: Xavax lamp is the only one to receive a "very good"
The Xavax LED 10 W tops the product test ranking with a grade of 1.5:
- The Xavax LED has a particularly high light output. This means that it generates a particularly large amount of light from the energy supplied. In addition, the colors are reproduced optimally and the LED withstood the endurance test for an astonishingly long time, according to the experts.
- In the test, the Xavax lamp shows itself as a top LED with no real weaknesses. It is available for around 11 euros.
The secret lamp test winner Vosla
The grades in the individual test categories of Xavax and Vosla differ only once and in the declaration. Because Stiftung Warentest criticized the missing note on the packaging that the Vosla LED cannot be controlled with all dimmers. For comparison: test winner Xavax cannot be dimmed at all. For us, this does not justify a worse grade (1.8). In our view, the secret test winner is Vosla:
- VosLED steals the show from the actual test winner: the 5.5 watt LED is even more energy efficient than the Xavax LED and reproduces the colors similarly perfectly.
- The VosLED also passed all tests effortlessly in the practical test and, at around 9 euros, is a serious competitor at the top of the ranking.
Stiftung Warentest: That's how much IKEA lamps are good for
The testers also examined two lights from the IKEA lamp department - at a price of around seven to eight euros:
- Ledare (dimmable): There were minimal drawbacks in the practical test for a very small flicker and the somewhat lower efficiency - Xavax and Vosla are simply better. The colors are also not quite as good as the test winner. Nevertheless, the LED is solid and compatible with most dimmers. Grade 2.0.
- IKEA's Ledare LED 5, 000 (dimmable) is significantly more efficient, but otherwise performs similarly to the first IKEA LED. Please note, however, that the LED is daylight white and not warm white. Grade 2.0.

3 tips for the perfect lamp
When buying the lamp, you should consider the following criteria:
- Luminous flux (specified in lumens on the packaging): Indicates the radiation output. The higher the value, the brighter the lamp.
- Luminous efficacy: Indicates how much light the lamp uses from energy. That is the measure of energy efficiency.
- Color rendering: the wall is red in daylight, but pink in the evening with a lamp? Then the color rendering is not optimal. A value of 100 is perfect, it shouldn't be below 85.
Test winner Xavax only 9th in the CHIP test: The CHIP leaderboard knows better alternatives
In the CHIP test center, we tested many other lamps that ranked the test winner from Stiftung Warentest:
- Up to 700 lumens: The small IKEA Ledars LED 3.5 W and 6.3 W are a real lamp marvel for just 4 to 5 euros: Top color rendering and a particularly uniform light ensure top positions in the best list.
- From 700 lumens: The Tiwin LED is particularly good for working and is at the top among the very bright lamps. Test winner Xavax, however, only comes in 9th place.
- We have summarized all tips and tricks for buying a lamp in this overview so that you can choose the right lamp for your next purchase.
Note: your old lamp does not belong in the household waste, instead you have to dispose of the lamp specially.
