Looking at the OP's link, they kind of look like they are using the small night-light sized bulbs. I haven't tried, but I'd guess one of those would fit through the neck.
Nope, it is a pretty small hole through a bottle. I have been actively looking for a bulb and fixture that will work. I have a perfect location for one of these.
Cool lamp. I might have to try this
Nope still haven't heard anything
