The throw distance is the farthest distance the flashlight can light an object. The cd/lm factor is the candela-to-lumen ratio. It shows how concentrated a light source's output is. A flashlight with a higher CRI can show colors more accurately. This is useful for examining objects, it helps tell colors apart in low-light or nighttime. The CRI of 66 can still be sufficient for many general lighting applications. Color fidelity is not critical in these cases.
