When in college we had a huge gray viewing booth that had those bright blue photofloods in it and cooling fans. Four people could sit around it and argue about the color pack for the next print in the darkroom. Many waiting just took stuff outside in the sunlight and did it. I still do that to this day with inkjet prints since all my rooms vary so widely in color temps.
I just pulled out my color temp meter and my room reads about 3,100K. I print in the D55 range when I make my ICC profiles. I probably should go for D50 too.
When I frame and hang, I like to use the picture frame lights over the prints. Some Westinghouse piano lamp fixture for $30 from hardware store that has two frosted T6 bulbs in it. I dip the bulbs in some Martha Stewart blue ("Bluebonnet") Transparent Glass Paint from Michael's Art Supply until they sort of look like the old blue photofloods so they won't be as orange. Put them on a wall dimmer and they really set off the prints. However, even dipped in blue transparent glass paint they are still about 2,700K measured as the tungsten low-wattage T-6 is pretty warm stock.
You could go the LED picture frame lights (Hograth Lighting:

Guess the saying is: "Print it for the final viewing conditions."
