Metal-Halide lamps give the best colors, next after the Sun, which is needed for one of my hobbies.
Sodium lamps gives superior amount of lumens per watts, they are perfect for lighting up my backyard especially if using at least 600W of singular lamp. I miss the times when cities were lighted by sodium, a blue-light pollution is one of the main reason of why I use to hate cities nowadays.
Also I use a cold-cathode fluorescent lamps in some places, they are almost as good as MHL and if used correctly (no often switch on/switch off) I need to replace them maybe once per 10 years. They are hardly to get nowadays, but I have enough of spare ones for all of my expected lifetime.
Not a gp, but my eyes can’t stand some LEDs. I don’t know the exact physics of it, but sometimes even a reflected/diffused LED light feels like I’m looking into a laser beam. Colors are also very off, like in a ~chroma fog that isn’t there. Other people don’t notice anything strange. I’d appreciate if someone explained why, because I’m a regular trichromat with no obvious vision deviations otherwise.
You made me think about it twice, tbh. I have passed regular vision tests, but never tested for tetrachromacy specifically. I can distinguish 22-35 lines here, depending on how far I sit to ignore jpeg line separating artifacts and how much I unfocus my eyes. https://kfor.com/news/test-how-many-colors-you-see-can-deter... (so silly to choose jpeg for a color test, oh internet). I don’t think I am a tetrochromat.
I failed another one which asks have you seen this color “before”, but honestly I’ll fail it even on 20 different-hue color palette because I have no color memory and my color vocabulary is on a “3-bit male” side.
Also failed “choose 2 identical out of 4” type. They are all 3+1 unless I peer very hard.
