It definitely dropped down quick, gotta have another cell ready, but it definitely wouldnt leave you in the dark.
With my rechargeable batteries I found that the step down is very rapid - maybe a minute of light left when the step down starts - sometimes two and three lumen levels at a time. That is why I had Dan make me some holsters to hold extra rechargeable batteries. They have come in very handy.
