I probably should have posted here sooner...
Here's where we are:
I have an approx 14x20 living room (open at one end under a drop header into a family room, in case that matters).
The 20' wall will be a photo gallery - an evenly spaced row of identically framed photographs at a consistent height (2' off the ceiling). We consulted with many lighting "experts" and "designers," experimenting with various bulb patterns, discounting tracks because we just don't like them, we determined that the best thing for those photos would be a row of 7 PAR20 (AllPro /HALO) cans evenly spaced along that wall, about 16'" off the wall (to the center of the can). We originally wanted gimbaled trims, but ended up deciding on small eyeballs. We will angle these towards the wall to get the coverage that we want.
50W Flood 25 Halogens were originally recommended, largely for color temperature and light dispersion. We have since been steered towards LEDs to save power and heat. I have had a hard time locating LED PAR20s with more than 300 lumens, > 4000K color temperature. I do not think that dimmable is a requirement for this, but that would be a nice bonus.
Any thoughts on bulb (or trim) selection for the photos? While I'm curious about other ideas for how we *could * have designed these lights, that's of secondary interest since the cans are up and the sheetrock is installed. (I said I probably should have come here sooner).
(Almost forgot: We have 6 6" recessed cans installed for "general lighting" in the LR as well. I know some will not like this, but we're not huge lamp fans and a fixture didn't seem right for the room. With the sheetrock up and the cans all in, I don't feel that this creates a "swiss cheese" look.)
Thanks for any suggestions!
