75W, LED Driver 24V, 3.125A, TRIAC, ELV, PUSH-DIM, PWM out, LTECH

The power rating was perfect for ~3 metres of 20 W/m band. The manufacturer has not written enough about the behaviour of PUSH-DIM, so I'll share: a 200...500 ms pulse switches the light on and off, and >500 ms it starts adjusting the brightness. In practice, it is very difficult to manually extract that short pulse; too often it is too short and it doesn't trigger, or too long and the brightness starts to change. It is generally unrealistic to switch from the first PIR sensor that comes along. Finally, as I was planning to have an automatic switch-off as well, I used an optocoupler and a microcontroller, and with that, producing a ~240 ms pulse in all cases is the least of the problems.
