BobsView, LEDs do have a fantastic lifespan, which should far outlast this sort of products typical lifespan. I think there are two issues here. First, these particular LEDs tend to be so cheaply made (die, leads, and wirebonding), and poorly tested, that they have much-higher-than-usual failure rates for this sort of product. Second, I suspect that the vendor probably does some final testing or color binning on the strand itself. If not, then I suspect they still prefer sockets to allow for a single strand to be populated with different colors as customer demand merits. Keep in kind that labor in these countries can be ridiculously cheap. As a for instance, a friend who was in China at the time relayed to me how the first major fiber optic deployment from Beijing to Shanghai was trenched entirely by hand (shovel). The use of trenching equipment was more expensive than manual labor.
i too agree puttng up lights such an imporant thing that it can make many couple's fight on simple issue. But the lights available especially the low cost ones are so bad in quality, you cant think of usng next year and another source of e-waste.
I agree! The smell of fresh balsam fir @ CHRISTmas time is VERY magnetic to the season! We don't have that many resources for good live trees here in FLA. The artificial plastic ones have taken over dominance unfortunately.
I am of the age when we recycled an awful lot of daily items, so when I see comments about "green", it makes me LAUGH like heck! We recycled diapers, beverage bottles, milk bottles, and all sorts of items. But, the past 40+ years has put consumers into this "throw-away" mindset, and now we're bombarded w/ the opposite message. Like it or not, but one of the stimuli for this mode of living was due to a lawsuit. It seems that someone bought a quart bottle of beer (remember those quart bottles??? ... I SURE do!), and there was a used matchbook still inside which survived the washing/sterilization process. That person sued, and that was the end of returnable beverage bottles.
I can tell you one thing..... IF there was MORE recycling at the home level by re-use, the landfills in this country & elsewhere would NOT be so overwhelming in size, nor would they be so expensive to maintain from a government point of view.
As we approach this "special" holiday (Holy Day) .......... BLESSED CHRISTmas to all & HAPPY, HEALTHY NEW YEAR, too!
Curie_US, I liked your green comment! It is funny to me that we take live trees, kill them, set them up in our home and then add small distributed heating elements to them all around. As a kid I never thought of this as being odd or wrong, now I am considering moving to a live potted tree with low power lighting and then planting it in the spring.
All that said;
I do really enjoy the balsam fir smell in the house and agree that the lights are a real pain the 2nd or 3rd year of use, which is when they start to fail. It took 3 hours this season to fix all the lights and at the end, I had 3 bad strings and 3 working! I wonder how hard it would be to fabricate a LED string (all parrallel) by hand? Does anyone have a suggestion for a cheap but robust connector that could be used for this effort? Merry Christmas..
Glen, there are a number of posts and blogs about various flicker free designs and how to make flickering lights not flicker. The common wisdom is that the cheapest lights use a single diode for half wave rectification. Apparently a full bridge is how most "hackers" fix theirs, and how some companies solve the flicker. I have seen reports that some use capcitance instead. One post I saw someone make a "dongle" out of old plugs to go inline that had a full bridge. The problem I see with this is that you now are running the LEDs twice as hard. Current limiting resistors in the strands are likely to overheat and the life may be affected of the LEDs themselves. While LEDs tend to be very high life, those in these light strings seem to be very low quality and very prone to failure. So... I decided not to tempt fate and just go for a strand that was flicker free from the start.
