  • There is evidence to show that violet does actually weakly activates red cones too. This is because the violet light starts creeping up to double the frequency of the lower end of the red sensitivity, and so it can actually successfully activate it very weakly. There are other factors that can lessen or even fully negate that effect though, it’s all kind of fuzzy.

    This isn’t strictly true. Even with the same beam pattern, LEDs will inherently have more glare. This is due to a combination of the physics of how LEDs project light in a more directed beam than more uniform halogens, and because they produce a cooler light that our brains interpret as brighter even at the same intensity as a warmer light. But yeah, the height issue has been a problem for a long time, even before LEDs were in use, LEDs have simply exasperated the problem there. And while mismounting them will lead to issues, upgrades are still a relatively small portion of headlights compared to factory ones.

    Ah, but we can go even further beyond in pedantry. This distinction is only exclusive when we’re talking about a living thing. When talking about the substances themselves, one is a subcategory of the other. A venomous snake is not poisonous, but a venomous venom is a poisonous poison.
