Hi all
High intensity LED's get their "brightness" by confining their lumen 
output into a very narrow cone. This is why you always see them in an 
array, not singlarly.
The end of the LED is a lens that does just this. To get a worthwhile 
side spread, you will need to mount the LED's of the array on a 
spherical or curved surface, so the outer LED's are actually angled off 

Oh, as an aside, before anyone gets excited about some of the "blue 
bulb" info in the link below, check this out
