The ILR LED tube light is designed around LEDs at either end of a cathode tube looking pipe. The pipe is lined with what looks to be fiber optic like threads that assist in spreading the LED light down the length of the tube. One feature that will really sell this product over some standard cathode tube is the beat sensor that has a sensitivity wheel that can be adjusted to sense the vibration from the speakers of your PC. Now there are plenty of cathode tube lights out on the market today with this same feature, but unlike the cathode tube lights, the LED light up faster the cathode so there isn't a delay while playing games. Though most high priced cathodes will be brighter then this LED tube, Antec advertises this tube would be best displayed at the bottom of your monitor to flicker with the vibration of your favorite game.
