It should work, OK, Gary.
The only problem is that the tubes are designed for max. efficiency at a
higher (in air) temperature, so efficiency may be lower. The improved
optical coupling might partially offset that, tho.
PS. Be aware that you need a lot more insulation than for 120Vac. The
starting kick is usually many hundreds of volts.

Instead of giving money to found colleges to promote
learning, why don't they pass a constitutional amendment

good as the Prohibition one did, why, in five years we would
have the smartest race of people on earth. -- Will Rogers
