The ones that look white when they are turned
off are the BL (Black Light).

The ones that look purple when they are off
are BB (Black Light Blue).

The GT ones are clear when they are off.  I
think that the GTs are also not made from
normal glass as it blocks too much short UV.

GTs are also far too expensive.  I think I
priced replacement tubes for my eraser and
they where in the $70 area.  Hooray for flash
I say :D

I was told by someone that for PCBs BLs and
BBs are as good as each other.  BBs just
seem easier to find in AUS as straight tubes.
