Very good GU4 LED lamps

The Evolution Pro MR11 LED lamps are identical, such as commercial GU4 bulbs and have an excellent light output. The lamp has "exactly" (with millimeter precision: +/- 1mm) the same dimensions (diameter, height, PIN-distance and PIN length) as a branded product (halogen lamp 12V / 20W, 205lm (at 90 °), 36 ° viewing angle ) made by a German manufacturer with over 100 years experience in the field of light and lighting. The conversion of 5 lamps therefore takes only a few moments and was done in no time.

The color temperature is given from 2700 to 2900 Kelvin and in the product details at 2800 Kelvin. Subjectively, I appreciate the color temperature rather at 2900 Kelvin (relatively white light, would say it's more of a fluorescent lamp as a "old" light bulb equivalent). Furthermore, also here without having measured it, should the beam angle of 30 ° and the specified luminous flux of 200 lm very good fit (comparison: the brand bulbs previously used has acc.Manufacturer 36 ° viewing angle and 205 lm and subjectively can be no great difference. except in the color temperature, to determine).

The only point that I have to complain about is that after the reconstruction of the bulbs now hum or buzz is perceptible a faint. While this is only in absolute silence audible (the compressor noise from the built-in refrigerator is louder), yet it's there when you turn on the light.

Now only is to be hoped that the lamps actually specified by the manufacturer actually withstand 35,000 hours of operation and extremely high switching cycles number of 1,000,000.
