You can pick the cheapest within a range, but not the cheapest overall.
E.g. I get relatively good bulbs by requiring CRI > 90. Or just requiring no flicker, as a feature. When the producer has more than one parameter to optimize, they seem to come up with more well-rounded designs. To say nothing of the useful features I mentioned.
Yes, I likely pay 2-4 times more for these bulbs. But they perform, and they stay for years of intense use. The cheapest overall bulbs are designed for other purposes.
