Vertical T5s

**Hi,

see pic of local council building with many hanging fluoros in foyer:

The hanging tubes appear to be T5s and there is NO enclosure.

An internal metallised strip is visible running end to end.

The low end has a neat fitting, white plastic cover.

Light emanates from all around the tube.

Google turns up nothing like it on offer.

What is it ?
