I currently have a series of LV halogen set-up and would like to replace these. I don't necessarily want to just swap in a new LED bulb, I'd ideally like to replace each fixture element but I don't see anything on this site that would allow me to purchase the elements? These are installed in recessed louvered step lighting boxes. If I can buy elements, please point me toward the correct product? I'm also planning to purchase a variety of well lights and deck lights in addition to these T5wedge elements, Thanks!
