I bought a 10m strip of LEDs from Amazon (Ruiviya Led Strip Lights,DC12V 10M 5050 300LEDs). It comes with a "power brick" (a transformer?) with a 3-pin plug for a wall socket. We had already had a lighting cable run from a standard lighting switch within a new build room to the base of a lantern window so we can run the LED strip around the base of the window.
I cut the standard 3-pin plug off the cable running into the "brick" and connected it to the cable running into the lighting circuit.
When everything is connected up the "brick" supplies power though a DC plug into an RGB controller box out of which run two wires that connect to the two 5m LED strips.
Disappointingly the only output is a short flash of the LEDs about every 4 or 5 seconds. Using the remote control I can change the colour of the flash but can't keep the lights on any longer. I guessed it is under-powered.
When I disconnected the cable to the "brick" and, instead, connected it (using an extension) to a wall socket all was well. It works fine.
But I can't re-wire the room to position a wall socket in a suitable position.
I presume my problem is that the lighting circuit isn't delivering enough power to the LEDs. I am pretty ignorant about electrics but I suspect that the power from the lighting circuit could be sufficient for the LEDs, but not through the "power brick" supplied - which is designed to be used with a wall socket.
Do I need a different "brick" of some kind that will take regular UK lighting circuit power and convert it to the 12V DC that the DC plug feeds to the RGB controller box?
If so, can anyone advise me of the spec I'd require and ideally a source?
Grateful!
