Bought these to put in kids glove box. Piece of crap lights. Id not do it again.
The ones I have appear very similar and may be identical. Check on Amazon if they expect to be used with a 14650 3.7v Lithoum ion battery. When so paired, they are very bright and useful. But get warm (why there is a heatsink).
If you do try the 14650 batteries, they may burn out faster. But with occasional use, mine have lasted 5+ years.
If dropped or damaged Li Ion batteries can ignite so avoid glove box storage. That is the reason TSA does not allow them in checked baggage.
