Technology Connections explains why narrowband LED holiday lights look harsh compared to incandescent bulbs and experiments with filtering white LEDs to improve them.

Just like these lights! HA! Yeah, so here’s the thing--I owed you this video. And honestly, the results were great! I have some more work to do (assuming no one listens to my plea toward the end) but now I know that what I want is at least vaguely possible.

The closing music was "We Wish You a Merry Christmas (Instrumental Jazz)" by E's Jammy Jams. You can get it for free--right now!--from the YouTube Audio Library. And here's a secret--my normal outtro song? It's from there, too. Just search "Floaters" and you'll find it. Don't tell anyone. You can support this channel on Patreon! It has been amazing what Patreon has done for this channel, but also for me (your dorky host) personally.

On “Ask HN: What are the best programmable holiday lights?”

This is a tangent, but I feel like we can't talk about LED christmas lights without linking to this video by tech connections: link to this video the tl;dw is that most color LED lights work by emitting a single frequency of light. Compared to classic christmas lights, which are incandescent filaments filtered through dyed glass, the LED lights look a bit... radioactive. My personal pet peeve are white LED lights. If you're not careful to buy the ones labeled "warm" they look cold, and imo, not very festive and inviting. Of course, this is all a matter of taste, but once I became privy to the difference, I could no longer ignore it. I guess I'm just a millennial nostalgic for the lights of my youth.

On “Why we're blind to the color blue”

Technology Connections did some videos on "Making Holiday Lights Less Garish", where instead of using narrowband colored LEDs he filtered white ones: link to this video

On “It was almost impossible to make the blue LED [video]”

The blue is nicer if you do that. Technology Connections has made 3 videos over the last 5 years mostly centering around how he hates the blue led lights used in holiday lights. I think I've only seen the 2 yr old one, but now that I have I can't unsee it. The blue is just too blue. If you see a set that is all blue instead of multi-color it's unbearable. It's just too blue. White light in blue plastic is where it's at. link to this video link link
