I disagree. It is a ratio of quality to price. People have different opinions about what the acceptable minimum ratio is, and it varies by product, and by time. For example, many people find Costco to hit the right ratio most of the time.

For example, I have been using LEDs and dimmable LEDs from soft white (~2700K) to cool white (~4000K) with no problem, all purchased at Home Depot/Lowes/Costco. Some have failed earlier than anticipated, but nowhere near enough to cancel out the cost savings.
