Pwnage, student John Duffy, designed a custom Photon Cannon back in 2013 and we redesigned it this year to make it smaller and lighter.

Here's what when into it...
CREE_XPEBWT-L1-0000-00C51 Xlamp XP-E2 High Power LED Star, Cool White = $3.49
TDK_CC6-1205SF-E Converter DC/DC 6W Sngle 12V to 5V 1.2A = $15.96
Resistors to dial in voltage and therefore brightness.
Army Surplus Len?
Custom Aluminum Housing
Powered by a spike relay

More work than a purchased flashlight, but the projection is a diamond (diode shaped) that is extremely crisp edged. John designed the aluminum housing to be slotted so we can slide the lens forward and backwards to set the focus at the nominal working distance.
