All I'm saying is that Xenon bulbs are not made for aquariums and probably never will be as there is no demand. Would you use a street or industrial MH bulb for your aquarium?
No point reinventing the wheel, they already make 70W halides for aquariums and I just don't see the need for anything smaller. So unless xenon bulbs can be proven more efficient than halides in terms of PAR what's the point in pursuing them? Maybe for fun, sure. Nothing wrong with that but don't make false/unproven claims misleading people into a bad purchase.
