I bought blue lightbulbs for my house and it was mostly a bad idea except for how I can go to bed with the lights on and wake up and instantly see without my eyes hurting from bright light so I have an edge on intruders, plus I sometimes sleep in odd places besides the bed so they won't expect me, but anyway, I found a thrift store that actually sells lightbulbs, who knew people donated those to charity, I am going to buy those cheap bulbs and go back to normal light, someday. A side effect of blue lightbulbs is that they last like a decade or something so it'll be a while.
