Earlier quoted context omitted.
Unfortunately, electronics design does not operate outside the bounds of economics. Given a target retail price of ~$1.25/unit -- many of these bulbs are the best design possible. The existence of poor quality products does not indicate malice -- many buyers demand low end products. Cost/quality/performance is an engineering tradeoff without a "correct" answer. The answer is up to the opinion of the customer.
I think that argument only holds when the customer is informed about those specific tradeoffs. The customer will choose the cheap bulbs because they can't be sure the expensive ones are better quality. They often aren't. Buyers want cheap bulbs, they don't want crap bulbs. If that means $1.25/unit is impossible, so be it.
And sometimes the better quality isn't worth the price. I bought a "Coochear" brushcutter on Amazon for a whopping $125 when my more expensive Husqvarna died due to a spun main bearing. At $125, I didn't care if it lasted longer than the time it would take me to remove the saplings that I needed to. The thing goes through 2" trees like they weren't even there. Yeah, it vibrates a lot more than it should and runs really rich, but it works a lot better than I expected for that price.
I know that I could have gotten another Husq that would work great but I really don't want to spend $600 for something that only gets used a couple times a year.
