I've got 4 or 5 of that same light. I think I generally run Duracells
and have not had much problem. If it is ever dropped replace the
batteries, I've had two do this and it only seems to take weeks -
regardless of how many hrs on the set. One rolled off a milk crate
and hit the concrete floor tail first, a few weeks later it didn't
work and I couldn't get the tail cap off.

Come to think of it the one in the motor home rolled off the table the
last trip - I should take some new batteries over and put them in it.
