  • The original Rudolph did not have a red nose. In that day and age, red noses were seen as an indicator of chronic alcoholism and Montgomery Ward didn’t want him to look like a drunkard. To complete the original picture, he was almost named Reginald or Rollo.
  • The Christmas wreath was originally hung as a symbol of Jesus. The holly represents his crown of thorns and the red berries the blood he shed.
  • The three traditional colors of most Christmas decorations are red, green and gold. Red symbolizes the blood of Christ, green symbolized life and rebirth, and gold represents light, royalty and wealth.
  • Tinsel was invented in 1610 in Germany and was once made of real silver.
  • The oldest artificial Christmas trees date back to the late 1800s and were made of green raffia (think grass hula skirts) or dyed goose feathers. Next the Addis Brush Company used their machinery that wove toilet brushes to create pine-like branches for artificial Christmas trees that were less flammable and could hold heavier decorations.
  • ‘Jingle Bells’ – the popular Christmas song was composed by James Pierpont in Massachusetts, America. It was, however, written for thanksgiving and not Christmas.
  • Coca-Cola was the first company that used Santa Claus during the winter season for promotion.
  • Hallmark introduced their first Christmas cards in 1915.
  • The first recorded date of Christmas being celebrated on December 25th was in 336, during the time of the Roman Emperor Constantine. A few years later, Pope Julius I officially declared that the birth of Jesus would be celebrated on that day.
  • Santa Claus's sleigh is led by eight reindeer: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder (variously spelled Donder and Donner), and Blixem (variously spelled Blixen and Blitzen), with Rudolph being a 20th-century inclusion.
  • Outdoor Christmas lights on homes evolved from decorating the traditional Christmas tree and house with candles during the Christmas season. Lighting the tree with small candles dates back to the 17th century and originated in Germany before spreading to Eastern Europe.
  • That big, jolly man in the red suit with a white beard didn’t always look that way. Prior to 1931, Santa was depicted as everything from a tall gaunt man to a spooky-looking elf. He has donned a bishop's robe and a Norse huntsman's animal skin. When Civil War cartoonist Thomas Nast drew Santa Claus for Harper's Weekly in 1862, Santa was a small elflike figure who supported the Union. Nast continued to draw Santa for 30 years, changing the color of his coat from tan to the red he’s known for today.
  • Christmas 2018 countdown has already begun. Will you be ready???
  • Why do we love Christmas? It's all about the traditions. In this chaotic world we can miss the "good old days." Christmas reminds us of that time.

Cutting a string of lights

Recommended Posts

Can I take a 50 light incandescent light string and cut it down to 20 lights?

Would it blow out quicker ?

What kind of lights are these? C7/9, minis?

I am assuming since it is 50 count that they are minis in which case those are usually in a way you cannot just cut them.

The answer lies in MATH. Now lets say that this string of lights are plugged into a 125VAC wall outlet. (work with me here a few volts one way or another is not going to matter, watch and you will see why I say this.) Ok so 125 / by 50 = 2.5V per bulb. What if it is actually 120V? 120 / 50 = 2.4V per bulb. Ok now lets take this to the next level. 125 / 20 = 6.25, right? So, you are going to have to find bulbs that are rated for 6.25 volts or 6.3 volts. Otherwise if you use the old bulbs, you are going to be dropping almost 3 times the normal voltage on those bulbs and they are going pop or flash like an old time flash bulb. Just keep repeating that math is our friend and math is fun. LOL Have fun

THANK YOU!! For the explaination, I actually understood that, Good Job......BUT I'm doing a singing pumpkin........Then what do I do with all the left over lights? do you suggest I find som sort of cover for the lights not used on the string? Any input would be appreciated

One other option, a single 1N4004 diode in series should give the equivalent of 54 volts of rectified AC. This should allow you to use 22 mini lights for full brightness. This way, if a bulb burns out, the shunt should still function correctly. If you really only want 20 bulbs you could wrap a couple layers of electrical around two bulbs and secure them with wire ties.

I really dont know what would happen with the diode so not going to even comment about that fix. The sock-it suggestion has merit and a caution. Mini lights do produce heat. Add a bunch in a sock and there might be a heat issue. I'll say again there might be a heat issue. But I would try it and see what the results are. Otherwise you can buy caps to go over the bulbs. Or some use electrical tape and tape over individual bulbs.

I guess the safe way is to cap the ones not used. ALSO I remember having a really old 35 mini light set .......Does anyone know if 35 incandecent mini light sets are available, that way I would only have to cap 15 instead of 30 which would be left from a 50 light mini set.

Thanx

My wife made a table decoration by putting a string of mini lights in a jar with a bunch of marbles. It looked pretty but quit after a few hours. When I took it apart to try to fix it I found the light string wires were burnt to a crisp. There is definitly a heat issue with mini's in an enclosed space.

Does anyone know if 35 incandecent mini light sets are available...

A quick Google search shows they're still available from several places. They use 3.5 volt bulb so you have to keep them separate from 2.5 volt ones. I try not to buy 3.5 volt strings for that very reason.
