On a 15 amp breaker can you put 10 plugs and 12 led lights on one circuit. The 12 led lights are replacing 2 existing ceiling lights the plugs have been there for years. This is in 2 bedrooms in basement.

you can as long as you will not draw more than 12 amps. As a rule each plug will draw 1 amp so if you have 10 plugs that will leave you with 2 amps left. Keep in mind if these plugs are new they should be on a arc fault breaker.

This is what I call pushing your luck.....

You would be right on or actually exceeding the limit...., and that's also depending on how much power your LED's draw as well. DON"T DO IT.....

So basically, as soon as someone plugs in a Flat Hair Iron and a Hair Dryer......something will spark somewhere...! ;(

Please don't cheap out and do it properly and get an Electrician in there to do it right and enjoy "THE REAL POWER" for many years to come.....

Your Welcome.....

To be compliant with the code, you can not do this.

We call it the 12 device rule and it essentially required you to limit the circuit to 12 power consuming devices. The only time this can be worked around is if the circuit is lighting only and you have to take the maximum wattage of each fixture to calculate the load. Now with LEDs it is a much smaller load then a traditional fixture, but the process is still the same.

You cannot use this approach with receptacles on the circuit because you do not know what will be plugged into the receptacle, so although it is probably fair to say that 12 LED fixtures use less watts then the two fixtures in total, but unfortunately that is not how it work.
