First of all: the one star deduction is the thing with the battery (see below) due, are for the expertise required to use Manufacturers and shippers not responsible. Sequentially: 1. Delivery time: Those things come by airmail from China, but have to go through the German customs. Therefore, 4-5 weeks are normally of the order until the arrival, you have to just know. For this madness Prize money but worth the wait! 2. Weakness of the battery compartment: During testing I noticed that the buttons on the remote to address times, sometimes not - irreproducible. On closer examination I came out that the button battery is loose and thus not always in contact. Since a pressure spring is missing up or down, as it is actually otherwise normal. Self-help: Since the positive contact is taken back in the unit on the edge, you can insert on the plus side of a small cardboard strips with, then the negative terminal has enough downforce - works! 3. The "disco" modes of the device: For the party room safe a cool thing (honestly!), But dispensable in the living room lighting are the more than half a dozen different flashing and flickering modes. You do not have to use so ... 4. The dimming effect: Was only questionable, I'm getting to. And now you just need knowledge that I have acquired (shoulder knock) by an extended test setup. I put in the following two things as immovable ahead: - It is a dimmable transformer used - Is a transformer (or switch mode power supply), which provides DC voltage. A. LED Ceiling Recessed Spotlights base GU 5.3, dimmable, however: the previously used halogen transformers supplied AC! Now I do not know if all LED lamps are alternatively be operated with direct or alternating current, but mine are there. Thus even the problem becomes apparent: In the lamps located electronics which converts the input voltage into a DC voltage, which need the LEDs that are sorted by type about 1.5 to 3.5 V DC. So these electronic works against the dimmer (!) And adjusts the input voltage and amperage to the needs of the lamp. You can not know that there is a previously dimmer at work yes. Depending on the electronics succeeds this adaptation more or less well, with the effect that the runtergedimmte power is compensated by the electronics, more or less, likely due to voltage increase at the expense of current (U = I x R). This means that my LED lamps when dimmed with this knob at the minimum (with the - key to a minimum shifted down) still 25% (Osram) and 40% (Noname) took power, 10% would have to be, This can be seen below. Moreover, the impact is not covered with the nominal values of the keys 50% and 25%, which is not surprising now. All this I have determined with an accurate digital consumption meter, as well as now in this case: B. operated with DC voltage LED lamps, tested with LED Stripes by Wentronic: Because here intervenes no corrective electronics, the specified values (100%, 50%, 25%, 10% as a minimum) are measured exactly achieved - bingo! Also, the response to the key strokes is felt spontaneous. Hope it helps ...
