No, the overall brightness of the projector is measured in ANSI lumens by the manufacturer, 1700 for the HD20 according to Optoma. Since they don't know what size and gain screen you are using, the manufacturer does not post fL.
Foot-lamberts takes the screen into account as well and measures the total light that is being reflected back toward the audience. Of the two, foot-Lamberts is the better method to use for setting up your home theater. That number depends on your screen size, screen gain, the rated ANSI lumens, zoom placement, and throw ratio. You should be able to see the fL estimate while using the calculator.
Full light control is a huge
benefit in this hobby (contrast - blacks, no ambient light washing your picture), especially for home-theater, and since you have it, you should be fine.
