If you’re looking to put together a first-class home theater, you’re going to need to consider every detail. Sure, the sound is great, the picture is oh-so-sharp, the blacks are black, the whites are white. But after spending umpteen thousand dollars on all that magnificent stuff, there’s not a penny left over for a bit of glamour in the lighting department. But wait. For a humble sum (about $38), you can install Lutron Maestro IR, a remote-controlled dimmer that can add a surprising degree of theatricality to your movie-watching digs without digging too deeply into your pocketbook.
