The bulbs were purchased to replace the bathroom in the mirror cabinet light classical Halogenpins. Since in the light of the space was limited, I have measured everything based on the specified dimensions previously - it should fit.
When unpacking it was noted that the bulbs are poured into a silicone. I like that - so the electronics are not directly in contact with your fingers and you break anything off. Disadvantage could be the resulting larger design and possibly also a lower heat dissipation. However, the heat generation is not particularly high even after prolonged switching.
Negative striking that the pins of the bulb with 10 mm are very long, with the normal Halogenpins these about 7 mm. I had not taken into account and so the bulbs do not fit into the socket. With a good Beiszange pins were quickly reduced by 3 mm too much. Now the bulbs fit in exactly - where they still "monstrous" act compared to normals.
Companies are the Pears with an iron core transformer - so here no minimum load is required and the pears run without flickering and without whistling of the transformer.
When using the mirror cabinet also a good color fidelity should be - Indicated a CRI of 75, which is often still a common value for LED bulbs. Since the Halogenpins the neighboring mirror cabinet nor built, I can well compare: Overall, the color reproduction is good, but missing the bulb red tones. One sees generally somewhat paler. However, if you do not have a direct comparison, it is hardly noticeable. The unhealthy pallor of earlier LEDs or fluorescent tubes you do not.
However, the direct comparison reveals yet another finding: the bulbs are sold as a replacement for 25 watt bulbs. The comparison Halogenpins are only 20 watts. Both seem equally bright to shine - the theoretical 5 Watt longer be invisible. Maybe that is also on the transformer and the power actually made by him (more power, halogen bulb burns a little brighter, LED not).
