Same! I saw that characteristic lighting in the preview thumbnail and got so excited.
Alec out there fighting the good fight for us.
while I disagree with his hatred of blue and green LED christmas lights being too much (I actually love them), I do love hearing about his process to find the christmas lights of his dreams.
I look forward to these videos every year 😁
I bought these lights, they're sitting on the kitchen table waiting to be opened and put on a tree! I'm so excited!
I feel like this video touched some larger philosophical points about technological progress. It's to work and create with restraints. If there are no limitations you end up with an unfocused mess.
I've seen that cropping up in a lot of videos lately from tech adjacent creators. Cathode Ray Dude veered off in his video about an HP laptop that had a feature that overwrote the Windows boot splash screen with a calendar view using the "Ring -2" management system into this kind of beautiful screed about basically why society is unraveling.

I literally wait every year for this video.
I would be happy if I ever care about anything 1/10th as much as this guy cares about Christmas lights.
Did he ignore flicker problems again like last year? Because flicker ruins lights for a lot of us
I actually ran my outside lights on rectified DC power last year because the flicker kills me
Say more about this. I also don't like flicker
Short answer, cut an extension cord in the middle and solder in a FULL BRIDGE RECTIFIER.
This gives you DC power. Now your lights will not flicker. They are also like 50% brighter.
But wait! The catch is that a lot of the strings are reversed in the middle so only half of it works on dc. You then have to cut the lights in the middle, swap the wires, and reconnect them.
Its a lot of farting around but looks nice.
I dunno. I just bought the Sylvannia led traditional white lights. Flicker free. Finally.
That's what's so stupid about the whole problem - the solution is known and easy but it costs a tiny bit more to make so lots of manufacturers don't do it. It just needs to run off DC instead of AC. Simple.
I wonder if you could use four of the LEDs themselves to form a full bridge rectifier?
Would still need a capacitor or something or it would flicker at 120Hz (in the US) but that's not much more cost I would hope.
Also those 4 would flicker more than the rest of the string.
