Pro:
+ Super bright LEDs (not quite reach the promised brightness of 20 W halogen lamps, but make this good competition!)
+ Pleasant light color, a little whiter than halogen, but perfectly fine and cozy
+ Good workmanship
+ Pretty large viewing angle (approximately 120 °)
Cons:
- Rükseitig mounted components (capacitor) can complicate installation
First of all: the Articles have been as it were "packed" of 1aTTack.de, manufacturer of LED chips is however Goobay.
When installed in the recessed spotlights advance had the reflectors of the spots removed and in some cases the pins are slightly reduced (depending on the available space in the casing).
Furthermore, it should be noted that an LED transformer is usually still needed.
Brightness and viewing angle of the LEDs are OK, even if the promised light output of 20W halogen lamps can not be exactly. However, they are close to the light output.
The light color is specified with about 3100 K, looks a bit brighter and more artificial than halogen bulbs, but are very pleasant.
All in all, recommended the LEDs.
