power calculation in color control - why don't watts equal voltage x amps?

Thanks in advance,

If you find the current value in input 1.2A voltage 234volt if i multiple both i will get 280W but CCGX shows 205W

Like that in output side 0.9A and 234V total 210W.but CCGX shows 159W.


Also wonder input side 205W power output side 159W power why it shows like this?

Hi @kaarthik,

There can be several reasons for this, but to at least introduce one of the elements that might cause this variation - please have a read of the AC Wiring chapter of the book Wiring Unlimited.

It explains why with AC capacitive loads Watts do not equal Volts x Amps.
