    I recently installed my Sony 60” LED TV on the wall and I am looking at putting LED (Warm White) around the set. I was looking for a USB version so I can plug it into the TV and let it power it when on and when the TV is off the LED Light is off.....

    Is this possible and where do I start?

    USB ports can only deliver 500mA at 5V. White LED strips use blue LED's with a yellow phosphour coating. Most 12V strips (White and RGB) have 3 LED's in series, and since each blue LED won't 'wake-up' until it sees around 2.5V, then you'll need at least 7.5V to get going.:(

    You may be able to get a USB 5V to 12V convertor, but it won't deliver more than 200mA, which is not a lot for a 4.5m strip that you'll need for a 60 incher, even on dim.:(

    Buy a 5m warm white LED strip (30/m), RGB LED controller, 12V 3A power supply. Connect the strip red lead (positive) to the controller V+ wire (usually white or black), and the strip black lead (negative) to any of the controller RGB output wires. Then just select that colour on the RC and use the brighness adjust for dimming. Simples.
