Some people report success, others have had premature bulb failure problems, runtime is usually pretty bad.. I don't consider it a viable solution for making an incan rechargeable.
I think most people put a 17670 in there with a strion bulb to go rechargeable.
If you find yourself getting into rechargeable li-ion cells, it would be better to stick with the 3.7V standard li-ion cells, this will eliminate the need for multiple charger types to deal with different types of li-ion cells down the road since most flashlights that are designed for li-ion cells are designed around 3.7V cells.
Please stick to quality stuff. AW protected cells and a Pila IBC are the standard recommendation.
