I just mentioned in another thread that I sold my survivorLED when I bought my D-Mini. I really like my D-mini, but I MISS my survovorled. The D-mini is brighter, smaller and Cree!. That being said, it runs 30 minutes on its rcr123a and then leaves me in the dark.
The SurvivorLED is about bulletproof, has the best switch of any light I have ever had. (feels the most solid and reliable) Will run for 3 hours and dim at the end so I know the end is coming. And is made to be used inside a burning building.
They are Different lights...and one really cannot replace the other. If I could only have 2 lights...One would be one of my Crees (I am not sure which one) the other one would be the SurvivorLED.
