Flux Wall Sconce

We just built a new home and I loaded it with Hubbardton Forge lighting as I had them in our old home and loved them. All of the others are great except this one, and I bought four of them. This one will only use a RARE halogen bulb, which are hard to find and expensive. You can replace the bulbs with LEDs, but...they do not turn off completely in this lamp only. The others I bought are fine. Halogen bulbs will damage the lamp over a short period of time and I am disappointed that I cannot get an LED G9 that works. The others have GU10 and they dim and turn off all the way with LEDs in them. Beautiful lighting like this should not have to use halogen bulbs. So disappointed in this sconce for that reason only.
