I wanted to do the no blue lights thing but incandescent light bulbs which one can place on a lampshade and which basically act as candlelight are forbidden in Brazil (for being inefficient). You can still buy the yellow fluorescent ones (or the LED ones) but they are absurdly expensive here for some reason (probably tax-related). Economically they still are more efficient if you keep them for 5years+ but it's just ridiculous that you can't get the incandescent ones which used to cost pennies.
