I'm using this light in a studio recording setup, and I have a very dimly lit recording room, with dim coloured lights. I keep it that way for the atmosphere, this light doesn't spoil that atmosphere, and focuses exactly on the music stand itself, I don't use the power adapter that came with it, although that's very handy to have as a backup, and to save batteries sometimes I only use one light, because both flights have a switch, this is a good light and very battery friendly.
