Why this model
The prismatic diffuser holds UGR below 19, which is the usual requirement for offices and classrooms and often the difference between an approved and a rejected installation.
Keeping the driver inside the housing leaves the ceiling void free for ductwork, which decides whether a retrofit is practical in an occupied building.
Where the ceiling plenum is used as a return air path, slotted and perforated versions remove the need for separate return-air grilles.
The 600 x 600 and 600 x 1200 bodies share the same LED board and diffuser, which simplifies spares and repeat orders.
