Hello, do you have both HS codes? Because there are so many types of LED lights and transformers, I don't know which one you have, I hope it can help you.

There is no need for a test report and a certificate of conformity, and a packing list is sufficient.
That's an electronic transformer, the electronic transformer can't measure the voltage when it's not loaded, and if you want to measure the voltage, you need to measure it when there's a load.
You can put it, remember to cover it with something in the sun . You can't get in the rain, and in terms of temperature, it's perfectly fine.
The toilet seat itself needs about 500 watts, mainly when heating, it needs such a high power, so more than 500 watts is fine, and it is better to buy 1000 watts. >>>More
The normal is 3 meters away, the transformer capacity is small should not be a big problem, more than 250KVA, the sound will be loud at night.
There is no harm in the distance of more than 4 meters, but rest assured.
