Need advice on a bulb

[dflet86]

Hi, I'm not sure if I'm posting in the right area. I don't really know too much about led light bulbs, and I'm wondering if there is a light that would be capable of projecting a beam of about 2.5" in diameter at a distance of around 12-14" and at a power of like 35,000 LUX. I'm not sure if this is even possible. Thanks so much for the time.

you should be able to use some type of optic to get the size and distance you require. An aspheric of appropriate focal length would likely do the trick

for the lux output, off the cuff converting lux to lumen 1 meter ~=39 inchs / 2.5 ~= 11. 35000/11=~3100 lumens

perhaps this one http://www.candlepowerforums.com/vb/showthread.php?t=226934

or my math is really bad
