I have an LED light bulb: Philips 60W incandescent equivalent
I've owned it for about a year and have been very happy with it. This morning when I turned it on, it started blinking. Not flickering, but a very deliberate one second on, one second off, one second on, one second off. This continued until I fiddled with the bulb at which point it came on and stayed on.
It has never done this before. I unscrewed the bulb and it rattles. Something in it may be broken, but it still seems to work. I couldn't find anything on the Philips website about this type of behavior. Does anybody know what it means?
