I forgot to mention that I bought Mom one of these things for Xmas, and the directions in hers (mine didn't have this) mentioned that when the light appears less bright than usual you should run it at full power for a couple of hours.

(Their English, however, could do with some brushing-up; as I was assembling the thing Mom was reading the directions, and she was thoroughly confused since the passage was written "...if the lamp should never seem to lose brightness...") --Blair "Quoth the raven, 'Not for more!'"
