A housing has a component storage cavity and an open bottom. A door covers and uncovers the open bottom. The door preferably has a latch that can be released with one hand. A window in the door transmits light from the housing. A partition divides the component storage cavity into a lamp section and a control component section. There is an opening through the partition. A removable control component mounting plate is dimensioned to cover the opening and thus become part of the control component section. A removable lamp reflector lies inside the housing behind the window. The mounting plate and reflector preferably each have a latch that can be released with one hand.
