The results are big different from my thoughts.
All 12v led strip light performed the same under different voltages, although they used different designs, IC, and LED chips.
All the 12v LED  Light Strips samples flicked slowly under 24v, and they can work well after being reconnected to 12V.
All the samples flicked quickly with a few LED Chips dead under 110v, but none of them exploded under 110v(This is totally out of my thoughts).
All the samples exploded immediately after being connected to 220~230V

LED light strips are designed with flexibility in mind, which includes the ability to be cut at designated intervals marked on the strip. In some types, you can cut every 5 pcs of LED, in some types, you can cut every single pc of LED. 

A quick answer: No, some LED tape lights have less qty of LED chips, but they can be more bright. The brightness of LED tape lights, also known as flexible LED strip lights, is a primary consideration for consumers during the purchase process. However, there is a prevalent misconception that the brightness of these lights

Amazon’s marketplace has been exploited by sellers falsely advertising LED solar lights, tarnishing its reputation and causing consumer losses. I urge Amazon, drawing from my quality inspection experience, to combat this through strategies like prioritizing honest sellers, focusing on critical product parameters, acknowledging the limits of quality certificates, and conducting spot checks. It’s time for Amazon to enhance quality control to protect consumers and maintain market integrity.
