Try resetting the bulb. You can reset the Element Touch by holding down the button on the side of the bulb for 20+ seconds.
If successful, the bulb will blink five times followed by begin pulsating (gradually dimming up and down between 0% and 100% brightness) for three minutes. If it does not pulsate, try holding down the button for 20+ seconds again.
Additionally, make sure the bulb is not being used on a dimmer switch; this would include wall dimmers, ceiling fan fixtures or 3-way lamps. Like most LED bulbs, the Element Touch is incompatible with dimmers.
