2 meter shallow cube lighting

[fish.freak]

Hi Guys,
Looking for a lighting options to cover 4 sq meters.
Not planning any sps at the moment and dosen't need complete coverage.
Thinking blue spot sting rays or sea horse but would like enough light to keep some corals.
Any ideas?

the current one is a boyd 3x 150 hiq with t5 actinic.
My other tanks are running zetlight which are ok but they dont last very long <2 years.
wanted ai but no stock here in malaysia also a bit expensive.
