4 ft LED Volumetric Surface Fixture
This 4 ft LED volumetric surface fixture provides integrated lighting for commercial and residential interiors. It uses an integrated LED array with a curved lens to distribute light evenly across the space. The aluminium housing weighs 12.5 kg and supports both suspended and surface mounting options.
Suits general interior lighting
Buyers needing a dimmable 3500K LED fixture to replace two T8 lamps will find this unit matches that requirement. It is not suited for installations requiring linkable continuous runs or integrated occupancy sensors. Projects demanding higher lumen output or different colour temperatures should evaluate alternative fixtures.
45.2 W maximum fixture wattage
The fixture draws a maximum of 45.2 W while delivering 850 lm at 107.2 lm/W efficacy. This single power figure determines whether the existing circuit and driver can support the load. Verify the wattage against your electrical plan before purchase.
