I love the 87CRI 5000K lamps; those and 3500K lamps are my favorite. I like cool white but it's kinda plain since most fluorescent lamps are of the cool white variety. Not a huge fan of /WW or /D though. They're a little extreme, though the /WWX ones are a little better since they don't have that pink vomit-like color to them. The /DX lamps I've seen have all been dim and flicker, not a fan at all. /D is a little too blue for me but I wouldn't mind using it in a room with a blue theme to it like a poolhouse or something, but we don't have a swimming pool and if we did it would be above ground and outside lol (can't have an inground pool on my yard because of the septic tank's leaching field. here's what it is. Basically is filters the waste water and lets it out into the ground through pipes surrounded by a rock area. That diagram is a little false with the tree over it though, as you can't have trees or bushes over the leaching field because the roots will get into the leachfield and really mess it up.
I know what a leechfield is...although mine is just a pipe draining to the beach in front of my house (After the septic tank). It was leeching though at one point after the neighbor ran a 20 ton excavator over it umpteen times with units of lumber...and fixing it they dug up the water line to the house and the phone line!
