Welcome to the Zoo Barbara!
Ray is correct. There are several different lamp colors and intensities available in LED's.
My wife also has vision issues and has a different bulb in her reading light than I do in mine.
I suggest you get on the net and do some research before you invest too much in bulbs. They last a long time but the initial investment isn't cheap!
If you are in an RV Park, see if any of your neighbors have upgraded and check theirs out before you spend any money...
