integration_time plus **1** second (fixed) blocked reliable measures

Typo here: () missing time.sleep(0.120self.integration_time+1) # takes minimal 1 second + 0.120self.integration_time

You want: time.sleep(0.120*(self.integration_time+1))

Fastest working is: time.sleep(0.105+0.100*self.integration)

Seconded! I use a local copy of this helpful repository and fixed it there but never reported here, sorry...

The initial clue for that comes form the official Adafruit driver and datasheet: https://github.com/adafruit/Adafruit_TSL2591_Library/blob/master/Adafruit_TSL2591.cpp#L316-L320 in combination with https://github.com/adafruit/Adafruit_TSL2591_Library/blob/master/Adafruit_TSL2591.h#L84
