I have been thinking of getting the 36 inch halfpiper fixture and converting it to run 4 200w SLI/H low pressure sodium lamps, but I currently do not have deep enough pockets for it since I am trying to save up some money for stocking up on some European fluorescent tubes in preparation for their phase out in 2023.
If it hasn't sold in a couple of weeks, I'll consider an offer. Already reduced it to $150.
