To respectfully add to Size 15's post;
The numbers from Flashlight reviews can be roughly interpreted such that if:
-the overall and throw numbers are the same or close, the beam may be flood like with likely no central hotspot
-the throw (throw="hotspot") number is in the order of 1.5x the overall number, the beam may be rather narrow
-from personal observation if the throw numbers is about 1.3x the overall, the beam has average throw with useable spill. This typically represents the average light.
IF the beam is completely narrow, laser-like, the overall and throw MAY be very close, so, the beamshots (if present) and descriptions are truly part of interpreting the numbers.
Keep in mind your intended use vs. what the numbers indicate.
Keep also in mind that manufacturers may change the lamp, LED, and/or the reflector/optics making the overall and throw different.
For example, Surefire recently changed the KL-1 on the E1L and E2L to have some spill. Therefore the numbers would change.
Enjoy.
