Most interesting! The El Cheapo LED thing that I've got did a half-a$$ed job with the Journey $5 and $10, (ie: you could see the blue UV ink), but all it does to the $100 is illuminate the yellow fibres. Not even a trace of the UV ink lights up.
The full-fledged fluorescent tube puts on a marvelous show and fully lights up both red and yellow fibres and the red and yellow ink.
