Lithonia Lighting CPHB ALO MVOLT SWW9 80CRI DWH Compact Highbay

One part covers both. The CPHB ships MVOLT standard, meaning it accepts any line voltage from 120 to 277 volts, so the same fixture works on 120V single phase in a small shop and 277V in a commercial warehouse panel. No voltage-specific ordering.

Both are the same fixture body with the same Switchable White and 80 CRI package; the difference is the Adjustable Lumen Output band. The ALO13 and ALO16 each give you a set of selectable wattage/lumen steps on the fixture, so you pick the band that brackets your target footcandles, then fine tune at install. Between the two ALO ranges and the switchable color temperature, the family covers 12 configurations across just 2 SKUs, which is why a lot of MRO buyers stock one and cover several mounting heights.

V-hanger brackets and two 36 inch chain lengths come in the box, so a straight chain hang needs nothing extra. The fixture is also suitable for cable hang, a surface-mount bracket, or a hook monopoint, and it is listed for pendant, surface, and suspended mounting. Cable kits and monopoint hooks are not part of the carton.

Ambient range is -40C to 55C, so an unheated warehouse, a loading dock, or a cooler aisle is within spec. It is damp location listed, which covers condensation and humidity but not direct water exposure, so keep it out of wet locations and off open exterior canopies.

Yes. The driver is 0-10V dimming as standard and thermally protected, so it wires straight to a 0-10V wall dimmer, a daylight harvesting panel, or a sensor with a 0-10V output. Pull the two low voltage control conductors to the fixture along with line and neutral.

Not as shipped. An emergency battery pack is available for the CPHB but it is a separate purchase, so if your code path needs the fixture to stay lit on loss of power, that pack has to be ordered alongside it.

It is DLC 5.1 qualified and listed as DLC Premium, which is the tier most utility prescriptive rebate programs require for high bay retrofits. It is also CSA listed. Check the specific measure list with your utility, but the Premium classification is the one that typically unlocks the higher per-fixture incentive.

Yes, that is the SWW9 part of the model. Switchable White lets you select the color temperature at the fixture rather than ordering a fixed CCT, so one stocked part can match 4000K aisles in one building and warmer common areas in another. Color rendering is 80 CRI across the settings.

The CPHB is a rectangular linear-format compact high bay, 22.5 by 11.5 by 2.4 inches, which throws a wider rectangular pattern down an aisle than a round UFO does. That shape suits racking runs, manufacturing bays, and retail sales floors where you want coverage along a line. For a tall open bay with no racking and a square grid layout, a round high bay distribution is usually the easier layout. Mounting height is driven by which ALO output step you select.

There is no relamping; the LEDs are integral. Rated life is 100,000 hours to 70 percent lumen maintenance, so at continuous warehouse operation you are looking at a very long service interval. Plan maintenance around the driver, not the diodes.
