Lithonia Lighting CSS L48 ALO3 MVOLT SWW3 80CRI

One part covers both. The CSS L48 is an MVOLT fixture rated 120-277V, so the same strip works on 120V branch circuits in an office and 277V in a warehouse or retail space. No separate voltage-specific SKU to order, which is why it standardizes well across a mixed-voltage building.

Both are field selectable on this 4 ft CSS strip. Lumen output switches between 3000, 4000 and 5000 lumens, and color temperature adjusts across 3500K neutral white through 5000K daylight, all at 80 CRI. That means one stocked part covers a closet at low output and a retail floor at full output, and you can match color to fixtures already in the space instead of ordering a specific K value.

Yes, the CSS L48 is 0-10V dimmable, so it ties into standard 0-10V wall dimmers and control panels used in commercial buildings. It is not a line-voltage phase dimming fixture, so a residential TRIAC dimmer is the wrong control for it.

Continuous rows are supported and the row aligner bracket comes with the fixture, so you can butt 4 ft sections end to end without sourcing a separate kit. Mounting is surface or suspended, so it goes straight to deck or ceiling, or hangs on chain or aircraft cable where you need the light closer to the work plane.

Cold starting is covered, minimum starting temperature is -40F (-40C). The limit is on the warm end: maximum ambient operating temperature is 95F (35C), and it is listed for damp locations only, not wet. So an unheated garage or cold vestibule is fine; a hot unventilated attic or an exposed exterior location is not.

No. This version ships without emergency battery back-up. If the drawing calls for egress lighting or a code-required emergency circuit in that space, you need a fixture with an integral EM battery pack or a separate emergency unit; this strip will not carry that load on its own.

Dimensions are 48 in. length x 2.22 in. height x 2.62 in. width, so it is a slim channel that fits tight above racking, in closets, or in low-clearance corridors where a wraparound or high-bay will not go. The channel and cover are code-gauge cold-rolled steel, not plastic.

It draws 43.4W and delivers over 4000 lumens at 125 lumens per watt, sized to replace a 4 ft linear fluorescent strip. For load calculations on a retrofit, that is the number to run against your existing ballast wattage per fixture.

It is CSA certified to both US and Canadian safety standards and meets the CSA DLC standard, and it is listed suitable for damp locations. That covers spec work on either side of the border without swapping part numbers.
