Advice on home wall display lighting (track or recessed?)
I have a 16 foot wide wall that I'd like to light for a professional-looking display of photographs in my home. I read somewhere not to use track lighting "can" fixtures because they're too directional, and to consider flood lights aimed at a 30 degree angle to the wall. Can anyone recommend any particular track or (preferably) recessed fixtures that they're happy with, and provide pictures of the installation, if possible? I assume 50 watt flood lights but am unsure how many I should install for this size wall. I would guess the lights would be 3 or 4 feet from the wall in order for the cone of light to be at about a 30 degree angle.
Thanks for any advice or ideas! I've been googling around the internet for a few hours and haven't really gotten anywhere.
