Bubble Lights

(Broadband version)

Bubble Lights have been around for quite a while now, about 60 years or so and they are quite simple.
A light bulb in the base illuminates the bubble tube and also heats a liquid inside usually methylene chloride, causing it to boil.
As the liguid boils, gas bubbles rise until reaching the cooler region at the top then condensing back again into a liquid.
There were a few variations in design, for example, some bubble tubes included a glass slug while others had oil in the tubes.
The biggest problem with bubble lights is that it is very difficult to replace the light bulb inside when it eventually burns out,
because most of them are cemented together. The bubble tubes may be reused as long as they are undamaged.
In fact, there are bubble tubes for sale on eBay that are over 50 years old and still in perfect condition!

Here are some Bubble Light decorations from my collection.

This is my Bubble light rebuilding procedure. Now you don't have to throw away burned out bubble lights!

 

Bubble Light Tree

Here is a NOMA 18 light 26 inch Bubble light tree model 503-G, circa late 1940s. I got it for $3.00 at a yard sale in spring of 2002.It's proof that the best stuff is right in your backyard. The previous owner replaced the bubble lights with C-6 bulbs as they burned out, so I had to replace them with reproduction Bubble Lights from Lions Den Antiques. Note: no longer in business!

Going forward to the mid 1970s is this Bubble light candelabra, Cat no 379. It's from A.C.L.A, the successor to Paramount.

Here's an exploded view of one of the merry midget bubble lights.

As you can see G.E. continued to use the bi pin base on their bubble lights.

Mini Bubble Light set.

Going forward again, to the present is this miniature 10 light bubble light set by Sterling.
The bubble tubes are much narrower because the 12 Volt miniature bulbs used give off less heat.
For example, 110 volt C-7 bulbs are 5 to 7 watts, 15 volt C-6 bulbs are 3 watts and the 12 Volt miniature bulbs used here are about 1 watt. Also note the different design on this set as the bulbs are placed horizontally.
