Did you know?
  • 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.

    What's up with these RGB based LEDs???

    Thanks! But that's a 2010 video. I would recommend checking out this last season's stuff: http://gordonlights.com/Videos/2011.asp Fabian

    Rgb Strings (not Pixel-level Addressable)

    Wow, how do simple questions escape simply being answered? Phil was the only one close to actually answering the original question. Stickybombs: Yes, you can drive RGB pixel strings using LOR controllers. Quite well, in fact, as the LOR DC controller makes a very reasonable, well supported 16 channel PWM controller that works with both LOR and DMX protocols. However, as Phil pointed out there are some load considerations to keep in mind. Related to the LOR DC controller: Each channel maxes out at 4A. So, theoretically you could run the RED pixels on string 1 out to about 200 nodes before maxing out the channel (assumes 20mA draw per each pixel component, 60mA total per LED when WHITE). Since you'd use channel 2 for Green and channel 3 for Blue, that means that the same 200 node string would draw three times that amount, or 12A. Your second string would use channels 4, 5, and 6 (R, G, B ), and for 200 nodes would consume another 12A. Now you have a problem. Each bank on a LOR DC controller is rated at 20A max (Bank A is channels 1-8, bank B is channels 9-16). So if you turned on both 200 node strings to white, you'd be drawing 24A on channel bank A and would overload the controller. The only way to ensure that you don't overload the channel bank is to reduce the number of nodes used per channel. Mapping the channels to the pixel strings as follows: Bank Channel String Color ---- ------- ------ ----- A 1 1 R A 2 1 G A 3 1 B A 4 2 R A 5 2 G A 6 2 B A 7 3 R A 8 3 G B 9 3 B B 10 4 R B 11 4 G B 12 4 B B 13 5 R B 14 5 G B 15 5 B B 16 NOT USED In order to avoid overloading the channel banks (20A max each) in an "ALL NODES WHITE" condition you would have to have no more than 2.5A per channel. Bank A will carry more of a load than bank B (because you're only using 7 of 8 channels on bank B so bank A sets the pixel limit at 125 pixels per string (125 pixels * .02A/pixel color * 8 channels = 20A) That would mean that one LOR DC controller can handle 625 pixels (5 strings of 125 pixels each) AT MAX RATED LOAD. You would also need some pretty beefy power supplies - at 12VDC, 40A is a 480 Watt OUTPUT. Input would obviously be higher, somewhere around 600 Watts. So, for your 9000 pixel example you would need 15 controllers. At $100 per controller, that's about $6.67 per channel, or $20 per string, which isn't too shabby for that kind of capacity and concentration. I hope this helps. Fabian

    Which C9 Is Better And Why!

    LED Retro bulbs have come a long way. I have spent thousands over the years looking for a bulb that would pass the abuse test. Manufacturers from all over the world kept sending me bulbs to test out and the results were never posititive. Oh, some came close, but not close enough. In 2008 a vendor sent me a new C9 retro to run through my "LED KILLER" testing, and I was very impressed. The manufacturer of those bulbs was Minleon. In fact, I was the one that created this video 3 years ago: The examples in the video used Cool White C9 bulbs and Light-O-Rama hardware and software. Additional testing was performed by others with D-Light and Animated Lighting hardware, and some of the still photos are of those testers. The Minleon product is generally a good product, and I do recommend it. Fabian

    Any Easter Displays?

    Though we've never really done any kind of "display" for Easter in the past, this year we decided to use our permanently-installed, GordonLights-designed RGB floods to create a 3 minute loop that rotates through "Easter-themed" colors. The sequence was downloaded into a LOR DC controller, which runs the lights every night with a more "standard" sequence. Believe it or not there were cars stopping across the street to watch the colors change! We didn't expect that! The photo quality isn't that great, sorry, but I think you get the idea. Fabian

    Powering DC controller

    Actually, in every metal-case AT/ATX power supplies I've come across the case itself is tied to ground, which is tied to the black output wires as well. So it should tie to both neutral and ground on the supply side. Fabian

    OK, I admit it. I so miss having a basement... Nice work, BTW! Fabian

    Powering DC controller

    Yes, everything is referenced to ground in an AT/ATX power supply, so in theory you can connect one lead to the +12V and another to the -12 and you'll get 24VDC. HOWEVER, the amperage rating on the -12V rail is generally .8 - 1.0 Amps, WAY less than the +12V rail. Assuming you're driving them to 80% max (mainly to keep the unit from overheating), your new 24 volt power supply is capable of .64 Amps. Really not much of a deal. I haven't looked at the MM circuit board up close, but given how cheap CAT5 tends to be I'm curious how much work it would be to split the circuit into two 12V circuits that could be jumpered back to a series-based 24V-compatible circuit. This way 12V die-hards would simply run 2 CAT5 cables to power the entire board. Just a thought. Fabian

    Powering DC controller

    OK, that's funny. It's also precisely the reason I designed my floods to run off 5V. Most of the PC supplies in my stockpile deliver an impressive amount of amperage on that rail. And everyone that knows me knows I "collect" them, and they'll stop being my friends if they don't pull the supply out of the computer before they throw it out. Heck, I might start giving them away at some point. Wait, I already have... There's lots of ways to skin this cat folks. Some more elegant than others, some more cost effectively than others, some neither of the above. But does that REALLY matter? There is no single "right" answer. Fabian
