Ok, I still haven't gotten around to putting my flowerpot base on yet, but here are some pics of my current state. First, here is what the lamp looks like with three bulbs lighted. That is a 100w (comparable) CFL in the middle and two 45w (comparable) CFLs in the ears. I like the uniformity of illumination.
The post is a 3" PVC pipe, prepped with acetone and painted with Fusion metallic texture paint. The globes are a 12" and two 6" acrylic globes. The 12"er is neckless, which I do not recommend unless you are using a commercially made post that accepts it. The XRay view will make clearer why neckless is a problem, so here it is:
See that disc at the base of the globe? It has tapered edges and was meticulously fitted to wedge tightly into the opening in the globe, like a cork in a wine bottle. Then there is the problem of how to attach that disc to the top of a PVC pipe. How about another disc that will center the first on the pipe and help prevent tipping? That works, to an extent, but the head can still tip too much, so how about a little threaded lamp tubing and a second disc further down into the pipe? Yes, that is nice and sturdy!
To get light in the ears I needed arms to hold the sockets in the right location, so I thought goosenecks would be ideal. I bought a couple of microphone goosenecks (available at Marrs for $4 ea) and quickly realized that trying to insert the arms into the globe and then reaching inside to bend the arms was nearly impossible. So I needed some way to pre-bend the arms and still get them inside the globe... which I could do if the arms swiveled:
This image shows the two positions of the arms. With them swiveled to the rear (opaque image) the bulbs will fit through the neck of the large globe. With them swiveled to the side (ghosted) they fit up into the ears. As you can see in the XRay view above, the goosenecks are mounted to thick dowels which extend through the top discs and seat in the lower disc. This way, even with the globe nearly seated (i.e. no way to reach inside) I can still adjust the bulb orientation by manipulating the dowels.
There is a 1-1/2" hole near the base of the post to admit an extension cord. A Fernco coupler (rubber sleeve and pipe clamps) joins the post to a toilet flange, and the flange in turn allows the lamp to be screwed down to a larger base (in my case, a flowerpot).
So, that is why I lay claim to having the
"most complicated Mickey Lamp ever conceived"! I am flirting with making things even more complicated by adding a photo sensor and a site sign. But that is for later. I will post more pics once I get the lamp "potted" and get some poinsettias to fill the top of the pot.
