Still use it on occasion, a River Rock (Target house-brand) 2×C light. Quite nice, clean beam (OP reflector), 1-mode with FC switch, but with only an XR-E under the hood. Used/Use it when I got C-sized alkaleaks to burn off.
The RR 1×AA light is a thing of beauty, too. Consistent regulated output ’til it’d run out of juice, then just drop like a rock.
Got a couple of each, “in-use” ones and “spares”. The in-use ones are still going, so…
Don’t even ask me how old they are. Circus City was still in business, used to pick through their and Target’s bargain-bin for DVDs. Looked it up, had to be pre-2008. So probably 2006 or earlier, if I had to guess.
