We have been retro fitting existing HID fixtures(shoe box,wall pack high bays etc....) using "corn Cobb LED lamps. Voltages from 120-277. Recently we've come across a site that has single 480 lighting where our usual of inventory of lamps aren't rated for 480 volt. We found a GE step down transformer from 480v to 120-300v rated for 375 va. Similar in shape to a conventional T8 ballast but longer 12" length. We've had six running for the past thirty days operating a 250 watt LED lamps(one per fixture,each with their own transformer)
Any thoughts or concerns?
