When Sony announced the PS4 wouldn’t ship with the PlayStation camera peripheral, gamers weren’t too fussed. It meant we got a cheaper console and confirmed that the PS4’s camera wasn’t a mandatory device like the Kinect is on the Xbox One.Losing the camera as a standard, included device did render the light bar on the DualShock 4 pretty much useless, however. And now we’ve learned that you can’t actually turn the light bar off when using the gamepad.That in itself is not going to upset the majority of PS4 owners, but it does pose a couple of problems. The first is battery life. With the light bar always active even when you aren’t using it, the battery in the DualShock 4 is going to drain that much faster. Sony must have accounted for that when deciding what battery to include in the controller, so it shouldn’t cause an issue.My other concern is with the actual light being emitted by the controller.When I hooked up the PS Move to my PS3 the light produced by the ball caused a reflection issue, as highlighted in my review. Sit in front of most LCD TVs using a PS Move and you are going to see the light reflected in the screen. It can be very distracting, but there’s very little you can do about it. Depending on how bright that blue light is emitted by the light bar on the DualShock 4, it could cause exactly the same problem.A lot depends on how your TV is positioned in relation to where you sit, and unlike the Move, you can hold the controller at an angle so as to stop the reflection happening. Even so, it would be nice if Sony added an option to the PS4 settings to disable the light when not in use. Another thing to consider is that if the light bar never gets used, Sony will probably remove it from the controller completely as part of a future hardware revision.
