The circuit is likely rated for 15 amps. The building code usually says not to use more than 80% of the available amps, so you have 22 usable amps. (Ontario building code, but representative of most North American building codes.

LED lights use a ridiculously low number of amps. I calculated at one point that each LED light in a set I was looking at used 66 miliamps (0.066 amps) ... which means 12amps divided by 0.066 amps per LED ... or 182 LED lights on a 12 amps circuit.

This really has nothing to do with the question since the question is about the dimmer load, not the circuit load. You can only load the breaker to 80% as you said which is 12amps but the question is about a dimmer switch which can only be loaded to 150w or 1.25A at 120v. OP cannot put 182 LED lights on his dimmer switch.
