Not bad driver – 28W 1400mA Power Constant Current Source LED Driver (85~265V) Reviews

I received the 4 pieces: 2 marked “JR Drive”, and 2 marked “QiaoDuoTianCong”.
The JR Drive is very good quality, made very accurately, very good work.
The QiaoDuoTianCong build quality is very poor,
in addition one thing exploded after 3 second work.
The output current doesn't achieve the value it was supposed to. I have measured all the 3 devices and the current was 1.23 A for all of them and not 1.4 A as announced. Output voltage: DC 23V.
The "JR Drive" is good product, good price, I recommend.
