You get what you pay for ... 4 1

Got it as part of a Halogen cable system sets 8 pieces of these spots. The positive first: The spots are bright and subjectively in brightness equal to a 20W-Glühspot. 35W halogen are yet again ne whole corner more, the indication in the title therefore absolutely wrong.
The light color is very pleasant and subjective color reproduction is very good.
What I do not like the 100Hz flicker and the quality of workmanship.
8 spots were directly 3 defective. One was, although the packaging was undamaged, completely broken and two disappeared at the onset of spots in the text in the connector pins in the lamp body. Apparently the glass adhesive used is not exactly brilliant.
At the broken spot I could directly analyze the exposed electronics. Sure, you can at that price do not expect much and accordingly falls from the wiring. Just a rectifier and a power resistor are installed next to the LEDs. In addition to smoothing, which could dampen the flickering, missing also protective measures, for example in relation to the voltage peaks occurring in conventional transformers when turning. So an early failure of the lamp is pre-programmed. Unfortunately, even expensive spots often forego on these measures, because that would make the lamp possibly 50ct expensive ...
I can therefore only Emepfehlen use of electronic transformers (flickering is here because the operating frequency of ~ 20-40kHz imperceptible and the voltage spike when turning is not dangerous, because much smaller) or in direct current systems (eg in the car / bus)
