Balko,
This would be way too dim for decent exposure times. Any lamp system you
use will need a pre-heated cathode to keep the lamp at the same brightness
when it turns on or a shutter system so that he lamp stays on all the time.
Go for a used beer sign transformer and a custom-made lamp $40-60 at a neon
sign shop. You will need a shutter under the lens.
