Ordered on line and they charged my credit card immediately. No communication for over a week. Sent e-mail asking for status and was told they were checking manufacturer availability. No communication for two weeks. Sent e-mail asking for status. No answer. The lamps arrived needing direct signature. Afterwards received an e-mail saying the lamps were being shipped. The lamps could not be mated to the pin kits because of how an electronic transformer had been attached to the back of the lamp. Wrote the manufacturer and Y Lighting. The manufacturer responded the same day. Y Lighting has never responded! Y Lighting obviously doesn't carry any stock or accept any responsibility. They just act as the middle man for the purchase. They sell high end lights such as Luceplan, Holtkoetter, Leucos, Artemide and many others but they have low end service.
