LED Holiday Light Experiments (for color)

Alec, there is another solution. Over here in the UK we are starting to get LED light strings where *all* the LED are phosphor based (like the white ones) and they are far more consistent in terms of light output and less strident colours. Probably why it's happening is it makes all the LED colours behave the same electrically (as they are all essentially blue) and that makes manufacturing and circuit design much easier. Essentially I think they are doing what you suggest, just with phosphor not plastic. Until then I've also found that colouring in inexpensive dollar store USB white lights works remarkably well for personalised designs too. Cheers, Charles.

When I was a kid I had great success using "Revell Email" paint on tiny light bulbs to make police lights for a model. Specifically their "transparent" red and blue worked great on 6V incandescent bulbs. Their paint comes in mini paint cans, maybe 1/2 o, it's intended for painting models they also market. Email is a German word for enamel, don't worry you won't have to configure POP or IMAP.

Found some warm white twinkles and multi color ones (with yellow! ) at my local Target. Fancy a drive to the outskirts of Philly?

Have you considered driving LED lights with a candle flicker LED like what is shown here?: <a href="https://www.instructables.com/id/High-Current-Flickering-Pumpkin-LED-Driver/" rel="nofollow noopener" target="_blank">https://www.instructables.com/id/High-Current-Flickering-Pumpkin-LED-Driver/</a> This could be used to emulate the 'shimmering' in twinkling lights.

You were trying REALLY hard to avoid using the word Christmas and Easter. As for LED lighting, the flickering issue is just going to get more widespread as manufacturers forgo adding the rectifier, capacitor and other associated electronics to save a little bit of money to get more people to adopt them. You'll just have to spend the money on higher quality LEDs

These are a couple years old from GE.

Alec, This is the BEST video that you've made so far.

I love it. Great video, Alec, Many (many) years ago, I had a mobile disco and I used to dip my own pygmy bulbs. I used to be able to buy coloured bulb lacquer in metal cans. I even mixed my own colours a purple and another half blue half green.

translucent coloured heat shrink?

TL:DR: Different colors of LED's have different properties, and so twinkling LEDs don't work well with multiple colors. Colored white LEDs would fix this. Apparently, different colors of LED's have different "voltage drops". That means that the voltage to run different colors of LEDs is different, and so twinkling affects red, orange, and yellow LEDs a lot, but barely affects green and blue LEDs. I am no expert though, but I think that's why the blue and green light don't twinkle as much. Of course, using exclusively white (or blue) LEDs with different color filters (or phosphors) would solve this very easily, an additional benefit of using white LEDs like you suggested! <a href="https://www.radio-electronics.com/info/data/semicond/leds-light-emitting-diodes/characteristics.php" rel="nofollow noopener" target="_blank">https://www.radio-electronics.com/info/data/semicond/leds-light-emitting-diodes/characteristics.php</a>

I hear what you did there!

Someone has probably mentioned it but you can get glass paint for making fake stained glass windows. It's a durable transparent paint . Just dip and dry.

And about the "twinkling": I don't like them, but maybe I'm too European for that :-P

Could you take a quick look at this set and see if it appears to be the correct type for the most pleasing form of twinkling? <a href="https://www.homedepot.com/p/Home-Accents-Holiday-150-Light-Miniature-Twinkle-Light-Set-TY150-TWC/205092367" rel="nofollow noopener" target="_blank">https://www.homedepot.com/p/Home-Accents-Holiday-150-Light-Miniature-Twinkle-Light-Set-TY150-TWC/205092367</a>

“These sets are still going for $4.99 where you save big money.” Love that you threw in the Menards ad reference! Made me go and watch old Menards commercials with Ray.

watch Mat's new Mission Impossible video if you haven't seen it, just mind blowing!

weird that you should release this today, because I had just re-watched your fairy light video earlier today, to know what to shop for, and I NOTICED you saying that you would make the follow up, and I was thinking "hey, he never made the follow-up!" - lol

There MUST be some reason they aren't doing exactly what you say. Are colored leds somehow cheaper? Try using "stained glass" paint for tinting lights!
