1×4 LED Flat Panel 40 W

The Satco 65-573 is a 1×4 LED backlit flat panel delivering 40 W of selectable colour temperature. It fits standard T-grid ceilings and is built for indoor or outdoor use in commercial settings. The fixture offers dimmable operation and a damp-location rating for versatile installation.

Suited for commercial ceilings needing adjustable

Offices, schools, retail, healthcare and hospitality projects benefit from the three selectable colour temperatures. The panel is not for buyers who need a higher CRI than 80+ or a non-dimmable fixed-colour fixture. It also does not suit recessed cans or surface-mount boxes that cannot accept a 1×4 T-grid lay-in.

Colour-selectable 3500 K, 4000 K, 5000 K

The single specification that decides fit is the selectable colour temperature of 3500 K, 4000 K or 5000 K. Installers choose the desired white tone on site without swapping fixtures. The 80+ CRI and 40 W draw remain constant across all three settings.

Questions about this item

How do I install the 1x4 LED flat panel in a T-grid ceiling and what step is often missed?

Lay the 49.02 x 13.39 inch panel into the grid, secure the integrated earthquake clips to the structure above, then connect the driver to the supply wires; the step often missed is tightening those clips so the 2.56 inch deep housing sits flush.

What maintenance will the colour-selectable 3500K 4000K 5000K panel need over its 50 000 hour rated life?

No lamp changes are required; occasional dusting of the lens maintains output, and the integral driver is designed to last the full rated life without service.

What limit appears first when the 40 W panel runs continuously at full output in a damp location?

The driver’s thermal protection will dim the fixture before the LEDs reach their temperature limit, so light output drops first under sustained heavy use.
