See attached. Making sure I'm correct here.
120v source.
97.2W/120V= .81amps

Is the light loss factor the PF? If so I need to multiply 120v x .85?

Thanks.

Here's the spec info. There in integral driver as mentioned on page #2. Why would that matter if they are giving the fixture watts. Thank you.

The light loss factors are not the power factor and will have no impact on the power used by the luminaire. The light loss factors are used to derate the initial lumen output of the light source to account for things like dirt accumulating on the lens, the lower output of the lamp or LED over time, and other similar items.
