First of all: All 3 models give the promised warm white light from warm white (2700K). It could also be heard in the dimmed state, none of the lamps a hum or buzz. As a dimmer a phase control dimmer model was used by 924 338 Bachmann.
The Osram Superstar Classic A60 I tested first, and the lamp immediately fascinated me. It is the cheapest of the 3 lamps, has the lowest power consumption with 10W and can easily keep up with a 60W light bulb. Negligible delay, almost zero dimmable (fully dimmed it still lights up with a 5-10% power), and no noise. The only complaint is a rare, light and perceptible only within look flickering fully dimmed state. However, since this happens with all LED lamps and strips used in the apartment I think this is due to our sensitive power grid in the old building.
5 stars for the Osram Superstar Classic A60, a strong buy recommendation.
Since my lampshade few swallows of light, I wanted to try a stronger LED bulb. The dimmable warm white models, there are currently unfortunately little choice, but to the great A60 lamp from Osram I thought that could be done in spite of the expensive price of the Superstar Classic A75 of Osram nothing wrong. Far from it. The light is just as enjoyable as the weaker model, so that the positive features, however, have already been completed. The performance is the A60 lamp very similar to a 'more' of light can not be determined despite the higher power consumption. The dimming does not work: With two lamps on dimmers it flickers in only slightly dimmed state, sometimes significantly, with only one lamp it is a little better, but still very annoying. Quite dim not leave the lamps, they always shine with approximately 40% of capacity. The Osram Superstar Classic A75 would only without dimmer used, has no visible added value to easily dimmable 'little brother', and is it too expensive. 1 Star.
After that, I was still testing the XQ-lite XQ13160 which match right from the values with the Osram A75, however, is a little cheaper in price. You will also light imperceptible brighter than the A60 from Osram, but can be compared to the A75 dim flicker - but unfortunately also only about 40% light output, which is me personally too little. Nevertheless, a great price / performance ratio, therefore 4 stars.
Conclusion:
Instead of Osram LED lamp Superstar Classic A75 13.5W advanced it is better to resort to one of the other two models I tested.
