Be carefull with buying led bulbs from China. Not every bulb that´s cheap is good for you and you home sweet home. I bought a bunch of this bulb´s to test them on Ebay. The seller gave the spec´s for 240V. This Bulb´s are not survive overcurrent that happen´s if you push the light switch. If you push the switch a few micro seconds the current and the voltage is higher than normal. The making current can be destroyed the bulb´s and they are not protected, a normal bulb get a short and the filament die´s. This LED will keep on running an starting to flicker and a sweet stench will follow.
It´s possible that you get a short in your electrical installation.
