LED Lamp: E27 Bulbs In The Test

Just in the dark season, more than ever, we have light. LED lamps are enjoying increasing popularity, as long they are affordable even for average Joe and points in addition to efficiency especially with long service life, instant light rendering and are. LED retrofits fit into any standard bulb socket. The magazine CHIP has now tested E27er LED in three categories.

Bad no section in the test the E27 LED bulbs. The result also shows that there are quite differences in efficiency, color rendition and co. and that the most expensive LED lights it does not automatically need to be the best.

What’s arrived in the CHIP LED lamp test:

Necessaryhome lists the following criteria which incorporated in the assessment of LED lamps:

Luminous efficiency (20%)
• Fidelity (30%)
• Uniformity (30%)
• Continuity (20%)

Evaluation was to better orientation in three categories: luminous flux, i.e. after brightness:

Category 1: up to 400 lumen (equivalent to approximately 25-40 watt)
• Category 2: up to 700 lumens (equivalent to about 40-60 Watt)
• Category 3: from 700 lumen (equivalent to approximately 75-100 Watts)

LED-lamps-buy: These values are really

Its clarity is what we like on the LED lamp test by CHIP. Also LED lay people without technical background knowledge can read it, are what LED lamps in the above disciplines in the average and which cut above or below average. The specific pricing help the classification and the traceability of price / performance.

The information on the packaging were evaluated for the LED-lamps-comparison. So, the specified Watts and lumen is alone such as yet not particularly meaningful. Dividing the luminous flux lumen due to consumption in Watts informed receives but how efficient a light source is really. Because the resulting value indicating how much light produces the led from the absorbed energy (watt). The processing played an additional role. Good LED bulbs have a sufficient heat sink which is able, letting if drain away the heat generated by the semiconductor crystal inside and so premature wear (turbidity) to prevent. Also colour reproduction incorporated in the overall standings, because it states how naturally colours in the light of the bulb will appear. For the interior lighting should be RA/CRI value over 80 are, what the most LED bulbs today easily meet. There were finally for an uneven light distribution points deductions by way of derogation from the ideal bell curve.

And what about the angle?

Some are wondering at this point perhaps, why comparison criteria such as angle, luminous flux or temperature during the test were not taken into account. After all, the luminosity at a smaller angle is stronger than when spread the same light output over the entire room. This “failure” was done deliberately. Because here it depends on the scope. Lamps will put maybe just accents with narrow half value angle are, while those serve as room lighting with a wide beam angle. Leaves the question according to the optimal viewing angle so not lump-sum to answer, but only after living situation. So, there may be LED lamps, which still are better suitable for your individual purposes, as the listed test winner – for example, if you prefer a different color temperature.

In any case information in the test, which LED lamps provide efficient light, colourfast light and evenly reflect its light. The complete test results is here.
