I bought a Artika Panadora LED Chandelier two years ago, now one bulb is flicking and need to be replaced. I have no manual on hand, even Artika site don't have the manual offer. It is a pendant light, total 29W with 21 bulbs. Is there some one know this Chandelier, can tell me what type/model of LED bulb it needs, and how to replace it? Really hope someone will know. Thank you.
