Stuck with a 8 inch flourescent tube for this one.
in reality just a cannibalized torch enclosed in a reflector box
that I lined with self adhesive foil.
Helps to spread the light about and stops
it bleeding to where it shouldn't.
The clear part in the kit was replaced with some 15thou
clear styrene which had some 600grit wet and dry treatment to the inside,
so it acted as a diffuser for the tube light.
The battery count was four AA pen cells for the tube and one 9v for the LED's.
