  1. Lightorama Computer controlled. All songs programmed by me. About 15000 LED lights. 16 channels. It is a collage of 8 songs. I have 46 songs done that play for the entire show.
  2. DSE, inside the two pods I got with the tester is what looks like a 330 ohm resistor, the little pod makes a fast simple repair where you are only squeezing the pod together to pierce the wire and keep the water and moisture out, I used my two up already, and got a few 330 resistors from radio shack to fix two more, after soldering the resistor in place of the bulb. I used some heat shrink tube to seal it off from the elements, worked like a charm.
  3. Tks hotrod for the sale, and 100 light strand multi, I just ordered 16 for my 10 foot Christmaslightshow.com mega tree for next year, been using incans since I made it four years ago. I needed 100 light strands to work correctly the way I have it arranged and stretched with my separate 6 channels to it. I have always bought the big box store leds since they came out at Lowes several years ago and were $17.00 a box, but they did last and I still have them, they are sealed like yours are. You cannot hardly find anymore sealed leds at the stores where I have been buying them, Target, Home Depot, and Lowes, and after a season or two the leads rust out of most of the leds with the replaceable bulbs or half the strand stops working even after trying to fix it with the LED Keeper Pro. Because of LED prices I was kinda waiting for price drops to buy 16 at one time on a limited budget. This will be my first purchase from a PC vendor and am anxious to confirm the quality that everyone talks about. Also, nice design on the website, easy to navigate.
  4. I would think that too, just like the outer coating of resin, if it contained impurities from substandard manufacturing the heat may have effected the resin surrounding the diode in turn damaging the diode. You cannot see it that well in the video or pic, but the white led resin had a yellowish tint to it like heat had discolored it. You being from Florida and me from Southern Louisiana, we both know what heat and humidity will do to things along with heat indexes. My metal sided, non-insulated building gets really hot during those mid afternoons and can only believe that it can't be good for them. I have seen stuff in my building over the years that has been damaged just from the high heat so I would believe anything is possible. This past summer we had heat indexes for several days at 115 and with these LEDs, wrapped on a piece of PVC pipe holder I made to keep them hanging instead of bunched up, I will bet they got real hot. I had it propped up on a nail right next to the metal sunbaked roof inside the building where everyone knows heat rises so it was the hottest area in the building.
  5. Agreed Orville on the gap left in the line if they are strung out vs wrapped in a display where it's a little harder to tell. I tried replacing blues and whites in one of the strands to no avail. The new led bulb was much brighter than the older ones in the same strand. I had done some more reading where the actual led itself, not necessarily a christmas string led any led, will degrade in brightness up to 50% in a period of time due to factors such as heat and usage, something about the phosphors around the semi conductor suffering from heat and age. The ambient heat also degrades the resin covering of the diode. I store these icicle lights over the season in an outdoor metal shed that gets over 130 degrees with the doors closed during our hot days of summer. I guess that does not help their life either. My other LEDs that are not yet that dim to me, I store in plastic trash cans in an open air shed that does not get near that hot. Although many led manufacturers claim 100,000 hours of life the usable full strength output life is way less some as short as 6000 hours. The advantages are still greater than incans for lower energy consumption and longer full output life, however the cost at purchase is not ideal if you get a short period of use out of them. Icans also suffer from output degration, however they burn out by the time they begin to lose their brightness. Also looks like regardless if the LEDs come from professional or non-professional sources, they will all degrade in light transmission dependent upon certain factors. Impurities in the resin surrounding the diode can have s effect on the life also. I read some of this from this site which explains a lot, pretty technical though: http://www.doubulb.com/led-technology.html I guess to try and get more full output life I might try to store the icicles in a cooler place. Now I know some people will probably post that they store all their LEDs in their 180 degree roof/ attic over the summer with no problems, but I am just trying to find solutions to benefit everyone. This may not even be what caused these strands to lose output, could just be cheap chinese manufacturing with below standard construction, but I'll give it a shot and report back in 2 - 3 years. If it works and I can save, or help someone else save, money, it's worth a shot. By no means am I an led technology engineer, all I can do is relay what I read from researching over the net. I will say that manufacturers claiming 100,000 hours of life may be correct, but they are not telling the whole truth regarding actually being able to use LEDs for that many hours. It does no good to have an led with 40,000 hours on it that has only 10% light output from 100% when it was new.
  6. Your apology is accepted merrymidget, in your reply to me, "and you expected what?", did seem a bit harsh and sarcastic as though I am ignorant for buying big box store leds, even though you did not intend it to be, hopefully. Believe it or not I make barely $40,000.00 a year after being in law enforcement for 28 years. I would love to purchase commercial strings but sadly with my pay I cannot afford to buy the "good" stuff and care for our family needs. I simply try to bring a little joy to my family during the season whichever way I can and one way is to run my little Mr Christmas box with LEDs I can afford. I have been a member here for many years and enjoy Chuck's site very much along with the forums, where, for the most part, everyone is trying to help everyone else out in the spirit of Christmas. I am also trying to save enough money to eventually go with a small channel LOR. I have a 10 foot Mega tree that I want to eventually outfit with some LEDs, but I have to use incandescants on it right now because I cannot afford to buy 32 strands of LEDs, even at "bottom of the barrel" big box store prices. My original post was intended to make a statement and inform others that might not realize that their LEDs could be dimming. I do realize I am buying low end LEDs and am aware that I could have problems which I already have had with the same Target icicles. The steel leads of the bulbs rust away to nothing and cause the string not to light. I have been stealing bulbs from a brand new string just to keep replacing these bad bulbs as they go out, but I also have figured out to remove the bulbs on a new string and put electrical grease in each socket to coat the steel and keep it from rusting. I do realize commercial sealed lights would, or should, not have this problem. I have purchased an LEDKeeper, tks Steve, to help save some old strands and have used it twice already to repair two old LED strings that had a bad bulb, those were some 8 year old sealed Lowes strands that had one bad bulb, so I used both of my small Pods that come with the Keeper. Inside each pod is the 330 ohm resistor to help complete the circuit without stressing the other leds. Orville, thank you very much for filling me in on the blue leds, I currently have 9 strands connected end to end, oh and they are not on the Mr Christmas, they are simply static along my eave. All 9 strands seem dim when a new one is plugged along side. Orville, from your experience, do you think that one blue led in one strand could create the problem with all 9? I will methodically take a new blue exchanging each out, and try one strand plugged in at a time to see if I can get them going. I did take the LED keeper pro and tested one of the whites in the bulb tester, it remained dim, so I am not sure if this could be the culprit, but I will give it a go and see what happens. Tks again. I included a picture of the strand looking directly into the led so everyone could see how dim it was. Btw I never noticed it before but while I was trying to take the picture of the string up close, which was not blinking and simply solid on, the camera eye picks up the led fading in and out about every 2 seconds although the naked eye cannot see it. When I switched to video on my phone, I captured the lights fading in and out about every 10 seconds alternating between themselves. Kinda weird. Merry Christmas to all of you Heres the video and the picture below of the how dim they are http://youtu.be/sGrSKBMHXEo
  7. I have about 100 led strands in my display along incandescents, I have been using LEDs for about 8 years and have come to notice some strands have become dim over time. All of my LEDs are non- commercial from Lowes, Target, Home Depot etc. My first LEDs were from Lowes, their brand, and they are still just as bright as the day I bought them. I have had some white/blue Target LED icicle for about four years and have noticed they have gotten dimmer. Dim enough that u can look straight into the led, especially the white, and it will not blind you. They are no longer crisp. To make sure I was not going blind, I plugged in a new set next to the old one and you can definitely see the difference. I posted this for others with similar issues and have read somewhere that some LEDs do fade or get dimmer over time. It's really a shame at 10 bucks a box that I will have to chunk the old ones and buy a bunch of new ones to get the lighting I want after only four years.

    Led Keeper?

    tks for the replies, looks like I will need to get one, besides the strings I have problems with like the rusting of the connectors on the lights, I think this would work good becuase I have trash canned a few over the years with only half the string working.

    Led Keeper?

    Has anyone tried this to fix led strings? http://www.ledkeeper.com/
  10. If you want them to just flash on and off and have your lights already, I use these on some C9s, they work great, this is what they are but I bought a few two years ago for 2 bucks a piece at either ace or true value http://www.amazon.com/Cooper-Wiring-Devices-C471-10/dp/B000H5Y2ES
  11. Tks for the nfo, I was looking for the multi 100 ct.
  12. Hotrod, similar to AGrisWoldXmas question but please refer to my post to see my dilemma: http://forums.planetchristmas.com/showthread.php/43766-Mega-tree-question-about-Home-Depot-LEDs Do ya'll carry any multi color 100 count strands, because I am trying to replace the incandescents on my mega tree but want the length to be able to go from the bottom of the tree to the top and back down with one strand thereby making two strands on the tree with only one of your strands, the 70 ct would be to short, I am sure. I do like the fact that yours are sealed especially here in Louisiana where anything rusts with our humidity even when it doesnt rain.
  13. Tks, I know had problems with rust issues on my other leds that are replaceable, had to use die electric grease in the sockets to keep them from rusting. As far as opening a box at the store, its online only. I am pretty sure they are half wave, but dont have a problem since MR C just blinks on and off. I am reading checking on some of the vendors right now to see the prices and strand count. tks again for the reply Ted
