I don’t order form Chinese websites or no name from Amazon because the CSA/UL/CE certifications are typically fake and the bulbs may not be safe to use. If they have insufficient electrical isolations for example the bulb may work fine until there is an unintended line surge which causes it to spontaneously combust where legal appliances would not have.
Then your insurance refuses to pay out because you used illegal electrical products.
Out flashlights are a grey area, they are not connected to line voltage and they are low voltage (hence may evade need for certification) but if an insurance company wanted to screw you and knew one of our lithium batteries started a fire they could deny you coverage because its not an item sold from a first world business and the batteries are sold in bulk to be used in packs which should be certified but are diverted to resellers who sell them individually for flashlights (against the wishes of most manufacturers agreements of sale).
