I have been told by 2 sources, including a fixture manufacturer that their has been a big shortage of transformers. Apparently there are financial and fundamental production issues at one of or the biggest OEM manu of transformers. Transformers are being allocated, certain wattages (900w) have been out of stock since Feb. I am busy forging ahead and frankly was not aware of this until very recently. I do not even know if it is fact and do not want to spread rumors. Have any of you experienced this? (shortage in supply of trans from many of the lighting manu's)?
