NiteCore Smart PD D10 for years,
simple, solid, reliable and almost too small- barely larger than the AA cell inside. Illumination intensity ramps from just enough for the cockpit tasks up to handheld spotlight to sweep the trees around a smallish field.
I don't think mine is currently in production, but the "NITECORE EZ AA LED" appears similar.
