  • 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.

  • 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.

LED's and custom wire length?

Recommended Posts

OK, fellow decorators. I have a question that I can't seem to wrap my head around. I searched for the answer as well... maybe im overlooking the answer. Im building some large "stick frame" stlye houses.


Im thinking about doing LED's to facilitate posible expansion in the future. Ive decided after careful reading to order the wire and LED's from a vendor, to mostly save headaches associated with rust, etc.

Heres the problem: I want to do custom length's of wire. How do I do this? I know that some manufactures claim that you can attach like 80 sets in a row etc, but what about shorter length's? Are LED's self regulating? It can't be that simple? The specific items Im interested in are:



Simple math dictates that I could run up to 437 bulbs. Not including wire resistance, and other factors.

Let me give a better example of an exact length. One particular "house" will need right at 140 ft of wire to go around 2 times. (Gives me 6 inch spacing). So 140*.016amps=2.24 amps. Got that part...

But lets say I only need 15 or 20 feet? I feel like Im missing something here? Wouldn't the bulbs fry if I pluged in to few?

Any and all help will be greatly appreciated.

As far as I know, you can't cut regular LED strings. You can cut LED ropelight between a certain spacing (just like regular rope light). And you can make custom length C7 and C9 stringers, using LED retro replacement bulbs.

With the link for the bulbs & wire you show, you could make a set as short as one

bulb and it would be fine...each bulb operates compleatly independant of the others.

I agree with xmasLightGuy.

Remember, these are C9 retro as in retrofit bulbs. And just like a C9 bulb, each LED retro bulb is actually 120VAC. If you come across any C7 LED retro bulbs, they too are 120VAC. Now, not all retro bulbs will dim and if you try to dim a non-dimable retro. Well can you say toast?

Yes, the ones you posted from Action lighting you can put on a string as short as one... As already mentioned. But the new ones, unless they are sprcifically marked that they CAN'T be dimmed, can be just fine. This goes for Action lighting only, not sure how many others are selling the dimable retrofit bulbs. Looks like they have sold out of most of their selection this year though...
