I was talking to a Coralife Representative today and asked him why my new double tube CF Coralife fixtures only had one cord. It seems that UL has a new requirement of one cord per fixture. I told him that I had seen them advertised as two cord fixtures for timing each light. His reply was that, either they had not updated their website, had old ones in stock still or had not looked at the lights they were getting to notice the change. Anyone else noticed this? You may want to check with a site before ordering. Might be effecting other manufacturers as well.
