Not a big fan of lights at nighttime, but I also rather have HPS instead of LED. Come to find out incandescent light bulbs are illegal to sell in Belgium. Luckily I found a nice lady who owned an electric store, who traded some incandescent light bulbs for some of my homemade soap 😎

I want to reduce the amount of blue light and light stress in my home, so I went to the local hardware store to ask if they still had some incandescent light bulbs. The owner told me they don't sell them anymore (like most stores) but I asked if they maybe had some laying around in the back of the warehouse or something. Long story short: she gave me 10 second hand incandescent light bulbs for free 😁

At night it should be 2,700 Kelvin. Warm white. Here in my city, they used to have landscape architects design the street and park lights. About 3 years ago we got a globalist mayor and city council. And they purposely changed it all to 7,000 Kelvin. Bluish daylight color. I think it is to depress the population. The color has nothing to do with brightness (lumina) but everything with mood. image
There's a huge market opportunity for non state licenced companies producing what people want and need. This is something you will only get on the free (black) market because states made it illegal. Prepare for your illegality. Monero will come in handy for both the merchant and the buyer.

Because it’s not just about color temperature, which is a superficial metric. It involves light spectrum, flicker rate, so forth. LED’s in the conventional sense offer isolated blue light, which is very damaging to a circadian system that evolved for full spectrum sunlight during the day and darkness at night. This gives you one example of the harms involved with the eyes
I have 2700 LEDs at my house. I wear blue light blocking glasses at night. Thank you for sharing the article, I'll see if I need to replace my lights. LEDs are gentle on the electricity bill, but I don't want to get sick.
In Europe, Philips in the '50's introduced Natrium lights for streets and highways. This orange 'single spectrum' light has 2 big advantages: (1) low electricity usage and (2) the human eye does not get night blinded , because the orange light only triggers the cones in the eyes , but not the rods. That's why image BMW had 'orange only' display in their cars for decades. (This knowledge has been lost on newer generation of car engineers ).
Sodium vapor replaced mercury vapor in the 70s through thr 90s because they cost half as much in electricity. They had a whiter light, but emitted a strong green hue which was more visible to the human eye. This had a different overall color effect than the orange sodium vapor bulbs. They also emit some UVC, depending on the glass composition, which was carcinogenic and degraded many plants and plastics.
It's like all the warmth, love and humanity left for the sake of cold efficiency
