Installing recessed downlights everywhere. This is one of the most common errors that lighting design professionals see. Builder spec versions of can lights can be very inexpensive, and people often assume that laying them out in a regular grid gets light everywhere. Unfortunately, this is not so. The optics of inexpensive can lights often allow only slightly more than half the lumen output of the lamp to escape. In addition, can lights, unless they are adjustable or wall wash fixtures, typically don't put sufficient light on vertical surfaces, which is where the eye perceives light. With an array of cans, we might waste nearly half our watts and still have a space that feels like a cave because the walls are dark
