full beam width angle or half[edit]

"2Ø1/2 Half intensity angle (deg)"

This is a very confusing subject, that needs explanation. It needs typical graph curves. LED etc beam width seems to be usually speced at full beam width, side-to-side, down to half of peak (central) power. But sometimes it is given as +/-, which seems to maybe be the angle from the central axis to one side? Please help!-69.87.203.97 13:15, 20 May 2007 (UTC)[reply]
