Thank you so much Snooze for the assuring advice.
The total COB LED power consumption is 180W (15W/m x 6m x 2 strips). The PSU is rated 330W (sorry, misquoted earlier as 130W) to have some margin for LED stability.
I am not sure if the lighting circuit has an earth wire. Any concern if there is none to ground the PSU?
Thanks once again.
