answer:No, because I ate my vegetables when I was a kid and don’t have a “Daylight only” restriction on my drivers license. Seriously though, like many people, my home lighting is 40W-equivalent for multi-bulb fixtures or small areas with 60W units in areas where a single bulb has to illuminate a fairly large area. Multi-bulb fixtures generally take lower wattage bulbs than single-bulb fixtures because multiple bulbs are brighter than a single bulb; three 40W bulbs in a chandelier easily put out the light of a single 75W bulb. Most lights are either 40W or 60W or equivalent because there truly is little demand for 75W or higher bulbs these days, at least not for interior lighting. They do make them, but they aren’t terribly popular (and thus harder to find; few places carry stuff that doesn’t sell well) because the lower wattage bulbs are plenty bright enough for most people. TL:DR – it’s lack of demand.
