Do you need an electrician to install a flood light?
Depending on where you want to install your floodlights, you may be better off hiring an electrician to do the work. However, if you’d like to hang lights over your garage door and don’t mind running conduit lines inside your garage, installing floodlights can be a manageable DIY project.
How much does a floodlight cost to run?
Cost to run appliance = energy in kWh x 21 cents. The outdoor floodlight thus costs $0.25 each day to run, or $7.56 to operate each month.
Do outside lights need to be on their own circuit?
Section 210.8(f) of the NEC states that all outdoor outlets must be GFCI protected, so does this mean that each set of outdoor lights needs to be on a separate circuit? The answer is… no!
Do exterior lights need a box?
Electrical code requires that all junctions be accessible in a box, so you definitely need one here. You have two choices (that I know of at least): cut a large hole in your siding and mount a retrofit light box into the wall cavity.
