That happens all the time with lighting. It's a p.i.t.a. actually. There really isn't much of a mark up from a supply house when realized it's out for bid. As far as the vendors are concerned, they don't want to take all that time putting a light package together if it's already been done. Lighting vendors always ask the job name. They have it on file. Most of the time it's a street price, I.O.W., all the supply houses get the same price and they forward that to the contractor. I've had electricians give me the job name and just call the lighting reps for a release of that job. Took me a total of five minutes and they fax it right over to me. I put my small margin on it and forward the whole job over to you. You can get substitutes cross referencing all lighting to a less expensive brand but they need to be approved in a submittal from the engineer.
Hope this helps you a little
