Low voltage Fluoro lamp??

After many years of great service my Eveready "Sport Gear" hand held Fluoro lamp has died......
I used this regularly as a portable reference lamp for the spectrograph.

Looking around all the "hand inspection lamps" are now LED - no use to me for spectroscopy.....
Has anyone seen a low voltage Fluoro lamp - the best I can find is a 12V 5W unit in a camping website for around $30.
EDIT: Checking the tube - Dr Google test....it appears the tube has gone!
Found one ( F4T5/D ) in the US - $1.....plus $42 delivery!! - still looking

Try Koala Wholesalers in Sydney 02 9552 1212
My company use to buy specialised tubes and lamps from them for various commercial and retail applications
Worth a try
Linear and compact fluorescents are slowly being phased out in Australia since 2011 and are becoming harder to source replacements

Try the lamp from EEPROM eraser.. they contain mercury.
Or, the inner part of mercury lamp (small tube) could be useful.
Or, neon glow lamp (from illuminated pushbuttons)
RS-Components have lots of them:

Ken, it's worth it to plan ahead.
Age replacement mightn't be a major concern, but what about accidental breakage?
