Loved but disappointed
Updated: I spoke with the co. They were very prompt to answer my questions. The lamp they said is supposed to turn off it it is starting to over heat. Because of all the circuits they don't want it overheating.<br /><br />I absolutely love this lamp.  But really disappointed it won't work after being plugged in (using or not using) after around 6 hours. I had to unplug it for at least 30 min and then it would work again. I'm a nail tech and work full hour days.  Sometimes over 8 hours. :'( I'm returning it, but maybe it was defective? Going to try another one and hope it doesn't do the same thing.
