Yeah, that's a typo. Typical of these kinds of pages.
And the pictures you linked are of the wrong fixture. You linked the 18,000 lumen fixture, which IS 160w.
The 12,000 lumen fixture is 100w.



Thats the bulb wattage not the total input. Theres usage and losses associated with the driver.

The pic above shows almost 160w total input.

When calculating fluorescent, HID, or LED fixture load, you have to factor in the total input current not just the bulb wattage.
The pic is of the wrong fixture.
In LED world, they tell you the full system wattage up front, not just that of the diodes. In fluorescent, HID...yes, you add up the components. In LED, system watts is published, including the driver.
