Yeah they’re nice lights. I’d have to work out a way to suspend them though.
The legs are somewhat extendible - retailer (or Arcadia) should be able to answer how much they might actually extend
I'm fan of the goose necks for their adjustability & "swing" - for moonlight (which is white not blue ) I adjust a Kessil to barely on & swing so it's mostly behind(or off side) the tank, tank is then mostly in shadow with just a small area lit by the (moon)light stream
Fish swim in & out of shadow & it's my favourite way to view the tank
