If you're installing LED lights that consume 150 watts each at 110 volts, each light draws approximately 1.36 amperes. Using an 18 AWG wire with a 10-ampere capacity, you could theoretically connect up to geometry dash seven lights (since 7 × 1.36 A ≈ 9.52 A) on a single 18 AWG wire. However, it's prudent to allow for a safety margin and consider the specific conditions of your installation.
