A Dark MOFO light installation has been closed after at least seven people suffered seizures over the past week.

The patients were taken to the Royal Hobart Hospital after viewing a light installation titled "ZEE" at the Macquarie Wharf One building.

Billed as "psychedelic architecture", ZEE uses artificial fog, stroboscopes, pulse lights and surround sound in a purpose-built room.

It was part of the Beam in Thine Own Eye program.

Anyone wanting to see the installation had to read several warnings and sign an indemnity form.

Curator Nicole Durling says an inspector from the Health Department was satisfied with the warnings.

"He advised that he has no cause to close us down," she said.

Ms Durling says there have been fewer adverse reactions in Hobart, than at previous exhibitions of the work.

"The artist had advised us that it's usually about a two per-cent response and we are currently running at about one per-cent from the visitors we've had through."

Dark MOFO organisers have voluntarily closed the installation.

Ms Durling says the installation will re-open as soon as possible after discussion with the artist about changes to warning signs.
