Only thing I had to do was build heads for the tubes. Simple and
cheap. A 2.5" PVC pipe cap and a Perko marine fresnel lens.

Sorry... that's a 2" PVC cap. Perko lenses are available here for about
$5 less than at your local marine supply outlet...

They fit snuggly in the cap after filing off the threads. Make a base
to hold the flash tube out of rigid plastic 2" in dia. Make a ring out
of 2" OD pcv pipe wide enough so that the lens sandwiches the base on
top of the ring. Secure the lens with silicon caulk, a couple set
screws, or a band of electrical tape.
