Abstract
A ballast housing has a bottom wall, a sidewall extending in a first direction from the bottom wall, and a first compartment that is defined between the bottom wall and the sidewall, with a first access opening remote from the bottom wall. The housing further includes an interior wall extending from its bottom wall in the first direction and is located completely within the first compartment, and a second compartment that is defined by the interior wall and is isolated from the first compartment by the interior wall. The second compartment includes a second access opening adjacent the bottom wall. A first component can be disposed in the first compartment and a second component can be disposed in the second compartment with the second compartment isolating the second component from the first component in the first compartment.
