Of course most of us prefer a bluer light for our tanks to make the coral 'pop', so Xenon might be a little to white.

I recall working on these in my former life as a technician. You could light up your tank from a mile away! All you need is a 28 Volt DC power supply that can pump out 55 to 62 amps, so somewhere in the neighbourhood of 1600 watts. Check your local army/navy/air force surplus store, perhaps you can score a second hand unit for cheap! Or contact Spectrolab directly, maybe we can do a group buy!

The corals will bleach before you even turn that thing on!
