Not the desired lighting effect but at least I received the color I have ordered. Not sure if it is working yet.
I have ordered the blue lamp, received a green lamp with little imperfections (missing green). Had to pay for the item because shipping back would have been even more expensive. Annoying because I don't want it and I haven't ordered it. Seller made a mistake and I have to pay for it. Sorry, I DON'T appreciate this business conduct.
