I have bedroom fans with central light and used to use 2 small round globes which are no longer made. The fitting face opposite ways and they have to be small to fit under the white glass cover.
I had been to 3 different electrical warehouses and no-one could help me. I measured the length and width of the 2 blown globes and had to find one to fit that. The stick globe had dimensions in listing at Lightning Outlet and I bought them and now have light in my bedroom again
