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.
