Was the program changed so the timer was set to dim to 30%, or was the light dimmed to 30%?
My CM15A was plugged into the wall when i noticed the light was not on. Then when I plugged it into my computer and looked at the settings it was set to dim to 30%, this had to happen by itself, because that lamp is a CF and I don't do any dimming. I always double check my programming before I disconnect for my computer.
Also, my CM15A is fairly new, with fresh batteries. Just the power failure was the only thing I could pin it to.
Thanks for all the help, I'm having fun with this stuff.
