Sorry for my English guys!
1. I didn't know if I like this thing, so I decided to start from something simple.
So it look's good in general. But there was a problem, if you use this LED's 1hour per day, after 3 days the batteries will die.
8 pcs:
2. I bought a 1.5 meter LED tape and a simple controller. The power i took from 12V socket.
Look's very aesthetically and has worked for a week.
Two mistakes, I didn't use voltage stabilizer and it was near hot air which is blowing in legs.
3. I bought DC 12V 4A Voltage Stabilizer and Wireless LED Smart Controller which allows me to control the light from phone or car stereo (2din android).
At this time all things was inside.
Now everything is working fine for a month.
