Which of the 12 volt LED light band and 220 volt LED lamp is brighter? What's the difference in electricity costs? Want to use it in the mall counter, 12 volts

Answer:

First of all, I doubt this lamp seller really understand it, can use 12V lights with constant voltage power supply 12V, you do not know this lamp with 1 meters is the number of W, generally 1 meters 30 meters 10W, that is 300W, you can buy a 300W constant voltage power supply, positive and negative with positive and negative light with constant voltage output, is very simple, do not worry about the brightness of the problem, as long as you do not exceed the constant power load. As you said, 220V lights, 220V lights directly connected with no real meaning, is the need to add an adapter in front of the adapter is 220V, this adapter is actually a driver.
As far as power consumption is concerned, as long as you have the length of the belt, you can use 12V or 220V
12V is commonly known as low voltage line, and 220V is high voltage line.A few years ago, high voltage line technology is not mature, low voltage line can be broken, a chip at worst, in series near the other 2 (3 string). And then the high voltage line is bad, one will be bad on the whole meter.Later, the high voltage line technology mature, and now also three chips in series, pay attention to the procurement, ask the relevant personnel, do not buy the oldest high-voltage wire products on it. When I was 12, the hotel project was still using 12V, and now I've switched to 220V altogetherBrightness of the big difference, cheap 5-6 meters per meter (I have seen the cheapest, 2 meters a meter, no warranty), relatively bright manufacturers, ex factory price is 13. 5050 patch specifications, if you use high brightness chip wafer. (it's hard to find on the market.)
