1- You can highlight your garage’s facade with outdoor wall sconces. If you choose only one wall sconce, install it on the side that gets the most traffic. Installing a wall sconce on either side of your garage door will make the lighting more homogeneous. Sconces should be between one-fifth and one-sixth the height of your garage door and be installed about 66 inches from the ground. Sconces that shine upward should be installed when a large space is available above them (above a door that doesn’t have an eave or balcony). Light fixtures that shine downward are appropriate for use in more confined environments. If you don’t have enough space on either side of your garage door, then install a sconce above it.
2- Garages with eaves can be fitted with a few recessed fixtures. Here are the recommended installation distances according to recessed fitting type:
MR-16: One to every 4 to 6 feet
PAR-20: One to every 3 to 4 feet
GU-10: One to every 2 to 3 feet
LED: One to every 3 to 5 feet
