Did you know?
  • 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.

Imitation Rgb Lights?

Recommended Posts

I am sure this is posted somewhere but I cant seem to find it. If I am wanting to have 3 different colors out lining the house can I just put a string of white, string of green, and string of red together and control them separately? This is my first year doing a bigger christmas show and I am trying to get the effects I want without spending all my money on lights since I have to buy the controllers this year. Any help is appreciated.

 

Thanks,

Lauren

Lauren, You need to just wind the three strings together to make what is called a super string.  Or :  You can use twist ties or zip ties to bundle them together. Then it is easier to handle and hang.  Hope this helps.

back in 2010 I still had not collected enough C9 LED's to do my roof line in all red, green, and clear.  In order to create the "effect" of r/g/c lights, I use 3 "super strings"  of mini red, green, and clear lights.  Here is a video (poor quality sorry) that you can clearly see the minis I used as a "roof line" @ 0:51 minutes on a close-up zoom.    Wow, forgot what it looked like 2 years ago hehe.

Another thing you can do to get the RGB Strip light look is use high voltage led strip lights. I ran 12 of them this year and everyone called them neon lights.

If you just want full string control not each individual pixel you can look into what they call RGB Dumb strings which will let you do any color but it will only change the whole strings color not each individual light.  I have found this may be cheaper than buying individual strands and it gives you an infinite amount of colors.  The lights on my house and bushes are individual strings of each color but my Mega tree is RGB which has individual control.

can you tell me how many strings of rgb you have on the mega tree  and the set up ,power supply ect  do the strings go up and down or around from bottom up and where did you buy them   thank you Blair

I am posting a long IM I received from FastEddy over at AUSChristmasLight forums, if you have not visited this forum they have an infinite amount of RGB knowledge starting with Eddy, they have put together several videos and powerpoint type slides that have a lot of very useful information.

 

Now the system i personally would look at for that tree is (assuming you already have the LOR version with E1.31)

 

ECG-P12R, will give you upto 12 universes of lighting, so you could use 8 outputs for your tree with 2 strings per output and then have options for adding other intelligent lighting later by having 4 spare outputs/universes. The cost of the ECG-P12R is $170, so when you compare the cost per channel to a built and tested E681/2 then the ECG-P12R is the most cost effective choice.

The reason the ECG-P2 is not my choice is because its more designed for a distributed load, where as the P12R is designed as a more centralized approach for use with things like pixel trees and matrices.

So i would download the ECG-P12R manual if you havent already done so and i would refer to the diagrams on connecting up the strings, you will be connecting 2 strings per output so you wont be fully loading up each output, but instead be using 300 channels from the 510 channels available per output.

If you wanted more efficient use of channels then you could go for the ECG-PIXAD8 which is 8 ouputs 8 universes for $$150, but for $20 more you allow yourself more future options.

 

Ok now the lights

This is something you will have to decide on if you want the square type or the tradition type of pixel for your tree and how you decide you want to make your tree will determine what is the best fit.

I am using 2811 pixels due to their cheaper price a good dimming qualaties, i use 5vdc for pixel strings as that is a far more efficeint use of pixels, but you can make your mind up which way you want to go by looking at this thread

Now the warning the 2811 pixel type is currently not officially supported by the ECG products, but you can use the 1804 pixel code for testing, the 1804 will give some flickering to the lights, but good enough for testing. There is a planned update soon and updating any of the J1sys products is very easy and requires no additional hardware to update. So if you dont want to use the 2811 pixel type then the 2801 pixel type would be the next best choice as this is fully supported

 

So for 16 strings of 2811 the cost = $18 x 16 = $288  (I actually bought 18 strands including shipping it was almost $420.00, but this also included several connectors mentioned below.)

for 16 strings of 2801 the cost =  $20 x 16 = $320

 

Now the power supply

 

5VDC power supply, I use more expensive meanwell power supplies, but the Cheap ones from Ray Wu will do

 

Again the size of the power supply is determined by if you want some extra room for later. Personally i woul just get 2 x 350 watt 5VDC power supplies, the total load of your 16 strings will only be 0.3 watts per LED = 240 watts of total load. The reason why i say 2 x 350 watt Power supplies is because firstly you never want to load up your power supply more than 85% and secondly it is always a good idea to have a backup power supply as i have seen the cheap Chinese ones fail in the past.

 

Now for connecting all this up will depend on what you want to do and use, i use the weatherproof 3 pin and 2 pin plugs from Ray.

 

You will of course need materials to build the tree and a box to house the controller plus other sundaries, but in a nutshell that is what you would need to do your tree and running from LOR E1.31 and using nutcracker.

 

Hope that helps make the picture clearer for you.

 

Now to answer you quantity question:

 

I purchased 18 strands with 50 pixels, then soldered them together (actually soldered the 3 pin plugs on and put them together using those plugs mentioned above) so with 2 strands together it makes for a 100 pixel strand which starts at the bottom goes to the top and loops back down, the Tree is in the shape of a half Mega Tree or like half of a cone.  I as well as FastEddy can vouch for Ray Wu he's very knowledgeable, he will combine shipping if you let him know what all you want to order, and most of the time no one has any problems.  Everyone is going to have a problem sometime (customs, shipping companies, etc.) but most everyone has had good results form Ray.  You just want to order as much as possible to help cut down on shipping costs, they aren't outrageous but they are coming from China so keep that in mind.

The ECG series of controllers have now supported the 2811 pixel for the last 3 months and there have been no issues at all with this combination. The 2811 offers the best value option when choosing pixels.
