Reservoir Canyon cave

Lights: Ra Clicky 140Cgt, SureFire L1

Received my replacement tails from HDS and took them for their first use inside a cave at the base of the grade. I used the Cgt and L1 and found that it's true what many say, that caves have a strange ability to absorb light. With the Ra and SF both on high, I had a combined output of around 210lm (250 with burst) and it was merely adequate after coming out of the sun. The L1 was clearly more useful, its focused spot lost less light to the dark walls and filled the narrow space well with its spot.
