Welcome to CPF......
But not so fast
it really depends on what you mean by "flood" -
I'll assume you mean wide-coverage -
if so, please take a look at this thread - with plenty of discussion -
Light Coverage - spill-diameter Pics
some of the measurements -
All lights with front bezel 12" away from wall
Light/ Diameter/ Angle/ Lens equiv on 35mm camera
Ray-O-Vac Lantern/ 43"/ 122deg/ 12mm (extremeWide - almost fisheye)
Streamlight Scorpion/ 36"/ 113deg/ 14mm (extremeWide)
SureFire 9P/ 26"/ 95deg/ 20mm (ultraWide)
Ultra-G/ 22"/ 85deg/ 24mm (very wide)
Dorcy 1AAA/ 21"/ 82deg/ 25mm (very wide)
ArcAAA/ 15"/ 64deg/ 35mm (semi-wide to normal)
So the fabulous classic ArcAAA (mine is circa 2003) was not as wide as the $6 Dorcy 1AAA, which in turn was almost as wide as the original CMG Ultra-G (don't know if the Gerber version has the same coverage....)
