Ceramic Christmas trees usually don’t fall under the normal scope of scaled models. It is a scaled tree, so I guess that makes it all right. My mom made this tree for me back in 1981. It used a night light bulb and due to the small size of the tree and the nature of the fixture that held the bulb, roughly 1/3 of the tree was lit. I always wanted to find a better way to light this tree. Over the years, I thought about an LED bulb cluster or shallower fixture. I then thought about pulling all of the plastic “bulbs” and replacing them with small LED’s. I couldn’t find anything that would fit and later realized that there were 75 “bulbs” and at $1-2 an LED, the cost of this project would have gotten out of hand.
Finally, I stumbled upon a fiber optics hobby kit and realized this was my answer. It took me two solid tries to get it right but in the end, it worked out really well.
Since I finished it last winter, a couple of the LED’s have failed. They were advertised as supporting voltage from 3-12v. The LED fixture includes a resistor so I was confident that my 9v power supply would be sufficient. I’m not sure why they failed. To solve the problem, I ordered the brightest LED “bulb” available in the size I needed and added my own resistor. The new LED’s were brighter and have held up very well.
