Two LED bar graphs. You would think they would be much alike, but no.
On the left: LTA-1000Y (2017 Thailand.) On the right: FJB10Y.
The polarity is reversed. The LTA has anode on the side of the first pin. The FBJ has the cathode on the side of the first pin.
The obvious difference: face colour grey vs face colour black.
Light colour is similar, but brightness is much different. I need to use 470 ohm resistor with the LTA, and a 2K ohm resister with the FJB.
