It may not be of much use to anyone with a recent iMac or MacBook, but folks with a Mac that doesn't have a built-in ambient light sensor will soon be able to get their fix courtesy of Nuovation's new Iris + Reflex combo. That includes the Iris USB light sensor, which is small enough to not obstruct any nearby ports, and works in conjunction with the company's Reflex software to dial down your display's brightness to suit your surroundings. In fact, it even bests Apple's standard offering when it comes to advanced settings, although we're still trying to figure out why you'd want to have two of the sensors connected. Still no actual pictures of the sensor, unfortunately, but you'll apparently be able to pick it up this summer for between $20 and $30.
