I personally think the "circadian" effects are overstated, but I remember being in a dimly lit sushi restaurant a couple years ago, and the cash register had a single blue LED on it. It was so bright that it illuminated the waiter, a piercing blue/white that was completely out of place in the room. Bright LEDs have no place anywhere where lights are dim, especially on electronics. Someone found this problem irritating enough that they started selling stickers specifically for the use of covering the damn things. https://www.amazon.com/LightDims-Black-Out-Electronics-Appliances/dp/B009WSN8PK https://www.amazon.com/LightDims-Black-Out-Electronics-Appli...
