Now this is interesting - the output/runtime performance pattern is remarkably similar to the Fenix LD10.While it is true that max output on regular alkaline/NiMH is not as high as the LD10, the runtime curves look the same. And on Med, the output level and runtime is virtually identical (with a slight advantage to the E03, likely due to the R5 output bin).Where the E03 differs is on how it handles 14500. On Med, the E03 is actually identical to the Fenix LD10 on all modes (i.e. direct drive). But on Hi, the E03 is even brighter than the Fenix (!), and on Lo has a reduced output level.
When I was looking into buying a AA light I was reading some reviews and this caught my eye from the Candlepower forums:QuoteNow this is interesting - the output/runtime performance pattern is remarkably similar to the Fenix LD10.While it is true that max output on regular alkaline/NiMH is not as high as the LD10, the runtime curves look the same.
