To add a little more to my above post, if you did use the old xfmr's DC for lighting, you would need some DC-DC buck converters to reduce the voltage for any LEDs and possibly some other types of lights. For very close to the price of the DC-DC converter you could probably purchase a wall wart of the proper size instead. You really aren't saving much, if any at all, with the old xfmr. The wall warts on ebay are really quite inexpensive. I imagine Amazon and other places that have them are also pricing them competitively.

Also, as a somewhat important FYI here, make sure that any wall warts you get are regulated power. The unregulated ones put out too much voltage (by several volts) until they are loaded down somewhere near their current rating, where they get much closer to their specified voltage. I believe Menard's had this problem with their early building power supplies that were causing lots of problems with the building lighting. The regulated wall warts put out the correct voltage all the time regardless of load. I believe that Menard's has now switched to the regulated power supplies and all is well with the building lights amd everyone is happy. Someone else could probably explain all this much better, but I think you get the idea here. I am not sure why they even make the unregulated wall warts? Possibly to save a small amount, few cents maybe? I'm sure the more knowledgeable folks here could explain that one, but I really don't know?
