Review on Enhance your Home Theater - Luminoodle by Power Practical: USB Powered TV LED Light Strip for Ambient Lighting - True White - Ideal for (24"-29” TV) by Kristen Moore

Of course I don't use it during the day. However, when it gets dark, I turn off the light in my room and then turn on the offset lighting. It definitely reduces ALL eye strain. I have a Himalayan salt lamp on my desk but one with the light off is not enough and I still have eye fatigue. This is a must if you want to turn off the lights at night while working/playing on the PC. I bought a medium (24-29" TV) for my 24" LCD and it was the perfect size. works great for a year but am waiting for the medium to be back in stock as I just recently bought a new 24 inch LCD monitor. To do this, you will need a male-to-female Type-A USB extension cable that connects the bias lighting and your computer. Using a USB hub is not enough to meet the power requirements. So don't ignore the backlight if that's the limitation of a USB hub.
