View Full Version : sockets for cast concrete Japanese lanterns
04-22-2009, 09:38 PM
I am looking for a source for sockets to mount in cast concrete lanterns. There was an example of these lanterns in the home made fixture thread.
I just need a source for the sockets and a recomendation on the type of lamp.

I've used SCB sockets and lamps for this, but these days I prefer a wedge base Xelogen. I get the sockets from my distributor. (Any decent LV lighting distributor should carry a variety of sockets.)
I've also used a section of cylindrical acrylic tubing, going over the outside with some coarse sandpaper to give a frosted or diffuse effect in a few of the types shown below.
Tachigata, or pedestal lantern
Ikekomi-gata, or buried lantern
Oki-gata or small lantern
Yukimi-gata or snow-viewing lantern

If you want a really cool effect in these lanterns get a module for flickering effect with your bulb so it looks like a candle.

Thanks for the info.
What I am looking for is a socket that will take a wedge base, or SCB10X lamp.
how do you mount the acrylic tube in most apps.

The ones I've used have a removable top piece and the height of that interior lamp space is greater than the square or hexagonal section where the lamp (or candle) sits.
With the ones I've done, I used 5" diameter tubing. There's a rule of thumb of how many Watts per inch distance from the acrylic... don't remember what it is right now because I used 12 W 93 SCBs or 7.5 W wedge base, so they don't get overpoweringly bright or hot.
I've had success with drilling four holes an inch from the top of the cylinder, 90 degrees apart, and running stainless steel wire to make a grid to center hang the lamp from. The acrylic cylinder is to keep leaves and rain water out, as well as diffuse the light. The "frosted" effect also helps hide the lamp and cable, but you have to play with it a little to make it least conspicuous. I leave enough wire coiled below to pull the whole assembly out for cleaning or relamping.

I ran out of time for editing... size the tubing to fit the space. A snug fit is good. I haven't had to use any adhesives.
Also, coarse sandpaper worked better for me than medium or fine, and I sanded the acrylic tube on both the inside and out for the greatest effect.

We did one in a zen garden that was large enough to accept a cast niche light inside with a 10w SCB lamp. I removed the reflector from the niche light and then took a small mirror and put it in the bottom of the lantern to reflect the light back up into the top so there was no shadows from the shroud.
This was much larger than your typical lantern tho. I have been wanting to go back to photograph the job but the owners are very very private people. Watched me the whole time I was at the house.

Here is a project I did a couple years ago. I used a flicker flame devise and for the sockets just your basic c-7 christmas lights sockets. For the lamps I am using 12v 15W candelabra flame light bulbs. The incandescent lamps have lasted a long time - they haven't burned out any quicker than the halogen lamps. They have been reliable probably because they are very lowly volted.
