Apparatus, systems and methods of 80/90 CFM ventilation exhaust fans for bathrooms with telescoping side extension brackets and side by side electric driven motor and blower wheel, and being used with or without lights. The exhaust fans can include a single main housing, that allows for a blower housing to support the motor and a blower wheel in a side by side arrangement. The exhaust fans can further include an outside wiring box that is externally located to the main housing. The wiring box can have support male plugs and female receptacles for supplying an electrical power supply to the electric motor and light. The side extension brackets can include telescoping members that allow the exhaust fans to be easily attached to structural members inside of a ceiling so that the exhaust fan has a vent cover attached to the ceiling. Inside of the exhaust fans can be light box with closed sides and bottom which prevents incoming air from passing directly onto the lights. Instead incoming air is drawn to pass around the outside of the light box so that the light box functions as a heat sink reducing the heat generated from the light.

The exhaust fan of claim 4, further comprising: a second elongated side telescoping bracket directly mounted along an opposite side wall of the housing, the second elongated side telescoping bracket being shorter than the first elongated side telescoping bracket. 6. The ventilating exhaust fan of claim 1, further comprising: a removable grill with a light covering the open bottom of the main housing, the removable grill only being used to draw air into the main housing of the ventilating exhaust fan. 7. The ventilating exhaust fan of claim 6, further comprising: a removable light shade that is separately detachable and attachable to the removable grill and light. 8. The ventilating exhaust fan of claim 6, further comprising: a light box having closed sides and closed bottom with the light being mountable inside of the light box, wherein air being drawn into the main housing by the blower passes around sides of the light box allowing for reducing heat generated from the light. 9. The ventilating exhaust fan of claim 1, further comprising: a wiring box attached to an exterior side of the housing, wherein the wiring box includes a male plug and a female receptacle inside of the box for supplying an external power supply to the electrical motor. 10. A ventilating exhaust fan of claim 7, further comprising: an elongated member which adjusts height of the shade relative to the housing. 11. A ventilating exhaust fan, comprising: a single main housing having closed side walls, closed top and open bottom, and an exhaust outlet extending out from one of the sidewalls of the single main housing;a blower wheel housing having a support base with a flat surface, and a sideway extending exhaust outlet coupled to the exhaust outlet extending out from the one of the sidewalls of the single main housing, the flat surface on the support base adjacent to the closed top inside of the single main housing;a blower wheel mounted in a vertical orientation inside of the blower wheel housing;an electrical motor for rotating the blower wheel that is side by side with each other inside of the blower wheel housing, the motor with the blower wheel housing forms an assembled blower which is mounted by a vertically oriented plate inside of the main housing, the vertically oriented plate consisting of a rounded top with a vertical tab extending therefrom, and a flat straight base and straight sides extending from the flat straight base, with one of the flat straight sides being bent into a trapezoidal section with a non-parallel angled side relative to the vertically oriented plate, first and second side flanges extending perpendicular from the flat straight base of the vertically oriented plate, the first side flange extending perpendicular from a bottom of the bent trapezoidal section, the second side flange being oriented perpendicular to the first side flange, the flat straight base of the vertically oriented plate being directed attached to the closed top inside of the single main housing by both of the first and the second side extending perpendicular flanges, the vertically oriented plate being spaced from one of the closed side walls of the main housing, the vertically oriented plate having additional flanges extending perpendicular from a side wall of the vertically oriented plate above the base of the vertically oriented plate which directly attaches the vertically oriented plate to opposite facing perpendicular extending members on an interior surface of the one of the closed side walls of the main housing, the additional side flanges being spaced between the top and the base of the vertically oriented plate, the vertical plate having a circular opening with four tabs equally spaced apart from one another extending into the plate opening for attaching to four complementary tabs on the motor, the assembled blower is mounted inside of the main housing so that the vertically oriented blower wheel allows for a smaller main housing and improved airflow over horizontally oriented blower wheels and with less parts;a light supported by a support member attached to the single main housing;a grill cover having vents and a light shade for covering the single main housing, wherein incoming air into the single main housing passes to the blower wheel without contacting the light;a wiring box attached to an exterior surface of the single main housing for supporting external wire connections for both the motor and the light; andside extension brackets on the single main housing for mounting the single main housing to support structures within a ceiling. 12.
