Strobe light LED schematic??

Hi guys. I am looking for an electronic schematic to build a strobe light with LEDs. It needs to be battery powered , very bright and as compact as possible. One application will be to stick the strobe light inside the clear tube of a Proton pack thrower and use a switch to trigger it. I looked online but have not found anything that meets my criteria. I dont know jack about electronic so I thought someone here might be able to help. Thanks!!

 

There are kits available that you have to build yourself . Simply wsap out the xenon tube connect a super bright LED. Runs off os a 9 nolt battery.
