Ah, an ARC LS is a pocket floodlight - the beam is slightly braoder than the surefire - not quite as much throw as the E2, but then again, I have a low dome. If you look at LED lights like the Surefire L4 - they are pocket spotlights

Then again, they cost more than the E2 <img src="images/graemlins/smile.gif" alt="" />
