The flashlight has no model number on it anywhere. Model number was probably on the packageing. It is a Heavy duty LED model with two ICR18650 3.7V rechargeable batteries. Never had much reason to use it, but bought it for dependability assuming that an expensive ($45) flashlight from Interstate would work OK. It will not stay on longer than 5 minutes with batteries fully charged. First time I took it back they said the charger apparently did not work and gave me a new one. Next time I tried it fully charged same result. Never got around to taking it back so no warranty. If you want bad quality for high prices, Interstate is the place to go User's recommendation: Don't buy a flashlight from Interstate.
